Cysts of one of the parts of the mediastinum: the superior part, containing the trachea, esophagus, thoracic duct and thymus organs; the inferior middle part, containing the pericardium; the inferior anterior part containing some lymph nodes; and the inferior posterior part, containing the thoracic duct and esophagus.
Neoplasms composed of tissue of the mesothelium, the layer of flat cells, derived from the mesoderm, which lines the body cavity of the embryo. In the adult it forms the simple squamous epithelium which covers all true serous membranes (peritoneum, pericardium, pleura). The concept does not refer to neoplasms located in these organs. (From Dorland, 27th ed)
Any fluid-filled closed cavity or sac that is lined by an EPITHELIUM. Cysts can be of normal, abnormal, non-neoplastic, or neoplastic tissues.

The upper part of the trunk between the NECK and the ABDOMEN. It contains the chief organs of the circulatory and respiratory systems. (From Stedman, 25th ed)
A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.
The visualization of deep structures of the body by recording the reflections or echoes of ultrasonic pulses directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1.6 to 10 megahertz.
A type of non-ionizing radiation in which energy is transmitted through solid, liquid, or gas as compression waves. Sound (acoustic or sonic) radiation with frequencies above the audible range is classified as ultrasonic. Sound radiation below the audible range is classified as infrasonic.
Changes in the observed frequency of waves (as sound, light, or radio waves) due to the relative motion of source and observer. The effect was named for the 19th century Austrian physicist Johann Christian Doppler.

Cervical thymic cyst in the elderly: a case report. (1/99)

Cervical thymic cyst is uncommon and usually occurs in the first and second decades. Cervical thymic cyst after the third decade is so rare that it is very difficult to diagnose in spite of its typical location. We present a rare case of cervical thymic cyst in the lower left - anterior of the neck in a 50-year-old woman. It showed well-defined, anechoic cyst on ultrasonography and non-enhancing low attenuation mass on CT. A typical anatomic relationship was noted between the mass and carotid sheath.  (+info)

First-trimester prenatal diagnosis of a thoracic cystic lesion associated with fetal skin edema. (2/99)

An unusual case of chest cyst diagnosed at the end of the first trimester in a dizygotic twin pregnancy and managed conservatively is reported. Between 11 and 14 weeks of gestation, ultrasound revealed a relatively large echopoor lung cyst occupying the left side of the chest, displacing the mediastinum and the heart. This was associated with increased nuchal translucency thickness and generalized skin edema. Subsequent sonograms showed complete resolution of the cyst together with the skin edema. The fetuses were delivered at term and had an uncomplicated postnatal outcome. This case emphasizes the role of reduced venous return as a cause of early fetal hydrops. Diagnosis and follow-up of a congenital lung cyst from the end of the first trimester should enable early intervention to be made.  (+info)

Surgical pathology of cystic lesions of the mediastinum. (3/99)

BACKGROUND: Mediastinal cysts are uncommonly encountered in a pathologist's experience. AIMS: To study the incidence, location, clinical presentation and histologic subtypes of cysts in the mediastinum. MATERIALS AND METHODS: Cystic lesions of the mediastinum, surgically excised over a period of 22 years were studied after retrieval of relevant clinical data and slides. RESULTS: Thirty-nine mediastinal cysts were encountered in the study period. Most of the patients (81.5 %) were symptomatic. Histologically, foregut cysts (19 cases, 50 %) were the most common followed by teratomatous cysts (ten cases, 26.3 %) and thymic cysts (four cases, 10.5 %). Bronchogenic cysts represented 63 % of the fore-gut cysts. Unusual lesions in the form of cystic mediastinal tuberculous lymphadenitis and cystic schwannoma were seen in three patients. CONCLUSIONS: Despite varied location and histology, clinical presentation of mediastinal cysts are similar. Surgical intervention is the preferred line of management.  (+info)

Cervical thymic cyst: report of a case and review of the literature. (4/99)

Congenital thymic cysts are uncommon and often misdiagnosed as either branchial cleft or cystic hygromas. This paper presents the case of a male child, who presented with a soft, fluctuating mass in the left side of his neck. Surgical excision revealed an ectopic thymic cyst. The histopathologic features of thymic cysts are diagnostic. Ectopic thymic tissue may be an infrequent finding, but it should be included in the differential diagnosis of neck masses, especially in children.  (+info)

Thymoma and multiple thymic cysts in a dog with acquired myasthenia gravis. (5/99)

An anterior mediastinal cystic lesion in an 11-year-old mongrel dog was examined. The dog showed dysbasia and vomiting due to megaoesophagus, and anterior mediastinal round mass lesion, approximately 35 mm in diameter, was found by X ray. Based on clinical examinations, the dog was diagnosed as acquired myasthenia gravis and was successfully controlled by anticholinesterase treatment for approximately 4 months. The dog died of thermic stroke and was necropsied. Grossly, fatty tissues with cysts containing yellowish fluid and white nodules were found in the anterior mediastinal area. Histopathologically, multiple cysts, neoplastic tissues, and atrophic thymus were found within the examined tissues. The cysts were lined by thin wall consisting of ciliated long cuboidal and non-ciliated round cells and were filled with eosinophilic colloidal fluid. Some extended cysts contained neoplastic foci within their lumen and walls. The neoplastic tissues consisted of mixed population of large epithelial cells with abundant clear cytoplasm and large oval nuclei, and lymphocytes. Immunohistochemically, proliferating epithelial cells were intensely positive for keratin and cytokeratin, and more than half number of infiltrating lymphocytes were intensely positive for CD3 suggesting T cells. All these findings indicate the neoplastic lesion is thymoma and multiple cysts are considered as thymic or brachial cleft cysts.  (+info)

MR findings in pericardial hydatid cyst. (6/99)

Pericardial hydatid cyst is rare. We present a 32-year-old man with a pericardial hydatid cyst. Chest x-ray film showed a spherical mass located left mediastinum. A pericardial cyst with low signal intensity was noted on T1 weighted magnetic resonance (MR) images. The cyst had high signal intensity, but signal intensity of folded parasitic membranes in the cyst were seen lower intensity on T2 weighted MR images. Based on these MR findings, pericardial hydatid cyst was diagnosed. The patient underwent surgical removal of the cyst. Histologic study of the cyst confirmed hydatid cyst diagnosis.  (+info)

Pathological analysis of congenital cervical cysts in children: 20 years of experience at Chang Gung Memorial Hospital. (7/99)

BACKGROUND: Congenital cervical cysts are frequently encountered in pediatric populations, and constitute one of the most intriguing areas of pediatric pathology. This report analyzes cervical cysts in Taiwanese children diagnosed at Chang Gung Memorial Hospital (CGMH) over the past 20 years. The pathologic and clinical findings are reviewed. METHODS: Files on 331 patients under the age of 18 years, with a diagnosis of congenital cervical cyst at CGMH from January 1, 1983 to June 30, 2002, were retrieved from the Department of Pathology. There were 204 boys and 127 girls. We reviewed the histology of all cases and correlated it with clinical information in the medical records. RESULTS: Thyroglossal duct cysts, the most common congenital neck cyst, accounted for 54.68% of all cases, followed by cystic hygromas (25.08%), branchial cleft cysts (16.31%), bronchogenic cysts (0.91%), and thymic cysts (0.30%). Nine cases (2.72%) remained unclassified. CONCLUSIONS: This is the largest series regarding pediatric cervical cysts in the literature to date. Thyroglossal duct cysts were the most common congenital cervical cyst encountered. Our experience indicates that each type of cyst has its unique location in the neck and is highly associated with its embryonic origin. Complete and precise clinical information is a prerequisite in order for pathologists to make accurate diagnoses of congenital cervical cysts.  (+info)

Rhabdomyomatous multilocular thymic cyst. (8/99)

The thymus is the seat of a diverse array of pathologic conditions given its embryologic roots. Multilocular thymic cysts, although well described, are uncommon, and one associated with rhabdomyomatous elements has not been described previously. A 15-year-old boy complained of sudden-onset chest pain of a month's duration, but was otherwise well. Chest radiographs localized the mass to the anterior mediastinum, arising from the thymus. A computed tomography scan demonstrated the lesion to be a multilocular fluid-containing cyst. A large, 15-cm cyst contiguous with the thymus was removed. Histologic evaluation confirmed a multilocular cyst lined mainly by mucinous epithelium with focal areas of ciliated and squamous lining. A prominent finding was skeletal muscle elements in the form of spider cells, strap-like cells, and foci reminiscent of fetal-type muscle with cross-striations. At the periphery of the cyst, thymic tissue with branching ducts and Hassall corpuscles were noted. No evidence of skin and/or its appendage structures, cartilage, or other differentiated tissue was seen despite generous sampling of the specimen. The muscle elements, most likely, were derived from thymic myoid cells, while the multilocular cyst arose from remnants of the thymomedullary system.  (+info)

66 year old African American female with incidental finding on an electron beam CT examination. Patient had a remote history of breast cancer 18 years ago with a left mastectomy.
Pericardial cysts occur at the rate of 1 person per 100,000 [1]. They result from failure of fusion of one of the mesenchymal lacunae that form the pericardial sac. Seventy five percent have no associated symptoms, and are usually found incidentally during routine chest x-ray or echocardiography. Seventy percent are located at the right costophrenic angle, 22% on the left and the remaining in the posterior or anterior superior mediastinum [2]. It is unknown if the size or position of the cyst corresponds to higher rates of complications. Pericardial cysts are usually asymptomatic, and are usually found incidentally on routine chest x-rays. Episodes of chest pain, tachycardia, persistent cough, cardiac arrhythmias and lower respiratory tract infection have been described. The symptoms can result from the pressure of the cyst on the adjacent organs [3]. Other reported complications include right ventricular outflow obstruction, inflammation and infection, pulmonary stenosis, partial erosion into ...

TY - JOUR. T1 - Non-cardiac thoracic ultrasound in 75 feline and canine patients. AU - Reichle, Jean K.. AU - Wisner, Erik R. PY - 2000/3. Y1 - 2000/3. N2 - The purpose of this study was to describe the ultrasonographic appearance of non-cardiac diseases of the small animal thorax. Ultrasound images from a total of 75 animals (26 cats and 49 dogs) were compared to cytologic, histopathologic, and necropsy findings. Clinical diagnoses included neoplasia of the mediastinum, pleura, or lungs (43); idiopathic mediastinal cyst (3); diaphragmatic or peritoneo-pericardial hernia (4); lung lobe torsion (1); pulmonary eosinophilic infiltrates (1); and idiopathic, chylous, congestive heart failure, or lymphangiectasia associated pleural effusion (14). In the remaining 9 patients, a definitive diagnosis was not obtained. Ultrasound-guided fine needle aspirate was performed in 56 patients; 1 of these also had an ultrasound-guided tissue core biopsy. Of the fine needle aspirates, 51 (91%) were diagnostic. ...
TY - JOUR. T1 - Intraoperative Ultrasound-Guided Excision of Cardiophrenic Lymph Nodes in an Advanced Ovarian Cancer Patient. AU - Moro, Francesca. AU - Uccella, Stefano. AU - Testa, Antonia Carla. AU - Scambia, Giovanni. AU - Fagotti, Anna. PY - 2018/11/1. Y1 - 2018/11/1. N2 - Objective Ovarian cancer is commonly diagnosed at an advanced stage. Complete macroscopic eradication of the disease is associated with improved prognosis. In this setting, the surgical resection of enlarged cardiophrenic lymph nodes (CPLNs) can help to achieve cytoreduction to no gross residual disease. During surgery, CPLN removal is usually performed either via video-assisted thoracic surgery or through a large transdiaphragmatic or subxiphoid incision. In the present case, we propose the use of an intraoperative transdiaphragmatic ultrasound to confirm preoperative imaging and to obtain a precise localization of the suspicious CPLNs. Methods A 50-year-old woman without peritoneal carcinomatosis was diagnosed with ...
A 39-year-old woman was referred with a 3-month history of pleuritic chest discomfort, shortness of breath on exertion, and occasional palpitation and presyncope. Physical examination showed no abnormalities. ECG revealed sinus rhythm. Posteroanterior chest x-ray (Figure 1A) showed a large, rounded, right paracardiac mass. Transthoracic echocardiography showed a cystic mass as large as the heart at the right cardiophrenic angle (Figure 2), interposed between the diaphragm (and the liver), right atrium, and lung. The left ventricular size and function were normal, though some right atrial compression was noted. Contrast computerized tomography scan (Figure 1B) revealed a homogenous right pericardial mass, 10.0×8.0 cm in size, with a density greater than that of the usual simple cyst (Figure 2A), along with a thin capsule suggestive of a pericardial cyst. The patient underwent removal of the cyst, which was attached to the pericardium over a small area (diameter=1.5 cm). She made an uneventful ...

A 66 year old woman presented in extremis with symptoms and clinical and radiological signs of simultaneous obstruction of superior vena cava and middle lobe of right lung secondary to compression by a massive benign anterior mediastinal cyst. Excision of the cyst at median sternotomy resulted in complete resolution of all symptoms. This report is unusual on account of a) the concomitant presence of superior vena cava and middle lobe syndromes caused by a benign cyst because of its sheer size producing obstruction of these structures and b) the complete resolution of all symptoms and signs after removal of the cyst. Benign anterior mediastinal cysts are unknown to cause either of the two syndromes. To our knowledge, it is the first report of a benign anterior mediastinal cyst causing either superior vena cava syndrome or middle lobe syndrome or both simultaneously. Etiologies of both superior vena cava and middle lobe syndromes are discussed in detail.
MTC is a distinctive thymic lesion that morphologically and pathogenetically differs from congenital thymic cyst. The latter is more common and derived from the third pharyngeal pouch. It is unilocular, thin-walled, and lacks inflammatory processes [3]. In contrast, MTC is always multilocular, and accompanied by inflammation. Its wall is thick and fibrous, with accompanying hemorrhage, reactive lymphoid hyperplasia and it contains usually turbid fluid, as in this case. MTC is believed to be the result of hyperplastic and cystic changes of thymic epithelium in response to an underlying inflammatory process of known or unknown cause [1, 3]. Thus, MTC has been documented in adult and pediatric patients with mediastinal tumors such as teratoma, lymphoma and thymic carcinoma [4, 5] and exceptionally in association with Langerhans cell histiocytosis of the thymus [2]. Additionally, MTC can be encountered in close association with underlying inflammation of thymic parenchyma and was thus described in ...
Bronchogenic mediastinal cysts (BMC) are a rare pathology, accounting for 18% of all primitive mediastinal tumors and represent the most frequent cystic lesions in this anatomic region [1-3].. They represent congenital malformations arising from an abnormal division of the tracheobronchial tree. In relation to the time of separation from the main tracheobronchial tree, the cysts may localize into the lung parenchyma or in the mediastinum, with percentages of 33% and 66%, respectively [4-6].. They are usually unilocular, rarely multilocular. Their wall is represented by a ciliated columnar epithelium lining, cartilage structure and occasionally may contain a mucinoid filling. BMC are usually asymptomatic, and often casually diagnosed. When present, symptoms are usually related to the area of occurrence and include chest pain, cough, dyspnoea, dysphagia, or emoptysis [7, 8].. Complications may occur, including infection, emoptysis, trachea or superior vena cava compression, intracystic ...

Figure 3: CECT chest showing a large well circumscribed cystic lesion in left lower hemi-thorax, abutting lateral aspect of pericardial cavity.. Question. What is the diagnosis?. Answer. All imaging studies suggested a large congenital benign pericardial cyst arising from the left cardiac border.. In view of this large pericardial cyst causing local compressive symptoms, cardio-vascular surgical opinion was taken and they suggested for surgical excision of the cyst. Surgical procedure was uneventful with postero-lateral thoracotomy in the 6th intercostal space and complete excision of the cyst measuring 9 cm × 7 cm × 5 cm, containing clear straw-coloured fluid inside. Biochemical analysis of the fluid favoured transudative nature according to Lights criteria (cystic fluid protein was 2.8 g/dL, Lactate dehydrogenase (LDH) was 110 U/L; whereas serum protein was 6.4 g/dL and serum LDH was 190 U/L). Cell count of the fluid was 180/cu.mm with 90% lymphocyte and 10% neutrophil. Histopathological ...
Foregut duplication cysts are developmental anomalies of the bronchopulmonary foregut and are common cystic lesions of the mediastinum. We describe a case of mediastinal foregut duplication cyst with in vivo H-1 MR spectroscopy on a 1.5T magnet showing a large metabolite peak at 2.02 ppm, attributable to N-acetylated compounds, in addition to a smaller peak at 1.33 ppm, considered to represent lipids. In vitro NMR spectroscopy (7.05T) of cyst fluid confirmed the presence of these peaks. In addition; a broad multiplet centered at 3.7 ppm, possibly from various protons of the hexose ring system, was also noted. Chemical analysis of the cyst fluid demonstrated the presence of N-acetylhexosamines, proteins, and lipids: Again, in vitro spectra of pure samples of N-acetylglucosamine and N-acetylgalactosamine were obtained for comparison, which better resolved the N-acetyl peak and the peaks at 3.7 ppm. The mucus secreted by respiratory epithelium and the mucous glands of the foregut cysts contains ...
The thoracic duct cysts located in the supraclavicular region are very rare masses, the etiology of which is not completely known. This article presents the clinical follow-up of a 35-year-old male patient diagnosed with throracic duct cyst situated in the left supraclavicular region and the patients condition is discussed in line with literature. The patient admitted to our clinic with a complaint of a mass in the left supraclavicular region that had appeared six months ago and that had been increasingly growing. A cyst excision under general anesthesia was performed to the patient who was pre-diagnosed with thoracic duct cyst following the radiological evaluation and the needle aspiration biopsy. There were no complications or a recurrence during the six months of postoperative follow-up. ...

The mediastinum is the anatomic region medial to the pleural sacs between the sternum, vertebral column, rib 1, and the diaphragm. The mediastinum is further divided into inferior and superior parts by a horizontal plane passing through the sternal angle to the T4-T5 intervertebral disc (Figure 5-1A). The inferior mediastinum is classically subdivided into anterior, middle, and posterior parts. Therefore, the four subregions of the mediastinum are as follows: ...
At operation dermoid cysts of the mediastinum are frequently found to be densely adherent to surrounding structures and often apparently invading them. This tendency is often attributed to infection, though positive cultures from the cyst contents have seldom been obtained. An alternative explanation may be that these characteristics are due to proteolytic enzymes produced in the cyst. A case is reported that would appear to support the latter hypothesis.

Abstract: Bronchogenic cysts are rare congenital lesions of the bronchial tree which are mostly asymptomatic. Rarely when the size is large it can compress on the adjacent structures in the mediastinum. We report a rare case of 10 month old baby presented with recurrent lower respiratory tract infection, was suspected to have a pericardial cyst on echocardiography. On further imaging it was confirmed to be a large bronchogenic cyst from the carina compressing on the left atrium and the left bronchus causing congenital lobar emphysema of the left lung. In view of compression of the adjacent structures patient was sent for surgery. Though congenital bronchogenic cysts involving pericardium and intracardiac tissues have been reported but mediastinal bronchogenic cysts compressing on left bronchus causing congenital lobar emphysema have rarely been reported. Key words: Bronchogenic cyst, Congenital lobar emphysema.. ...
Bronchogenic cysts are rare congenital anomalies that arise in early gestation as a result of abnormal budding of the developing respiratory system.1 Abnormal bronchi or bronchioles may form large saccular structures that may later form cystic lesions. Bronchogenic cysts predominantly occur in males and are often solitary and rarely multiple. Typically, bronchogenic cysts have ciliated epithelium with cartilage, smooth muscles, and mucus-producing bronchial glands similar to the bronchial walls. Bronchogenic cysts do not have alveolar structures because the abnormal budding occurs before the formation of the alveoli. Their location varies and depends on the embryonic stage of development at which the abnormality happens. Intrathoracic bronchogenic cysts have 2 radiographic classifications based on location: mediastinal and intrapulmonary. Mediastinal bronchogenic cysts account for approximately 20% of all primary mediastinal masses.2 Mediastinal bronchogenic cysts appear as smooth, rounded, ...
Intracardiac cysts are an uncommon occurrence, and intramyocardial cysts are rarer still. Various types of intracardiac cysts have been reported in literature, the most common being parasitic, such as hydatid cysts.1 Other rare cysts include bronchogenic cysts, blood cysts, intracardiac epithelial cysts (occurring in isolation or as part of a congenital polycystic tumor of the atrioventricular node or of a teratoma), and pericardial and epicardial mesothelial cysts. However, no reference to an intramyocardial mesothelial cyst was found in recent literature.. Herein, we describe what we believe to be the first reported case of an intramyocardial mesothelial cyst mimicking a benign cardiac tumor.. Mesothelial cysts are usually congenital, lined by a single layer of mesothelial cells, and they contain clear water-like fluid. Pericardial mesothelial cysts have been described to be more commonly unilocular, as opposed to multilocular.. On echocardiography, cysts are anechoic to hypoechoic. On CT ...

Intrathoracic mesothelial cysts almost always arise in the mediastinum, and extramediastinal mesothelial cysts are extremely rare. Here we describe a case of mesothelial cyst derived from the chest wall pleura growing after thoracic surgery. A 63-year-old Japanese woman was referred to our department. She had undergone total hysterectomy for cervical carcinoma and two lung wedge resections for metastatic lung cancer on the upper and lower lobes of her right lung and lower lobe of her left lung. After the thoracic surgery, an intrathoracic chest wall mass was found, which grew gradually. Computed tomography demonstrated a 2.0 × 1.8 cm low-density mass without contrast effect. Magnetic resonance imaging demonstrated a low-intensity mass in T1-weighted imaging and a high-intensity mass in T2-weighted imaging. Thoracoscopic excision of the mass was performed. The cystic mass was thought to be derived from her chest wall and was pathologically diagnosed as mesothelial cyst. Five years after the surgery, she

Definitive histology of the specimen was infiltrating colloid adenocarcinoma with immunophenotype of enteric adenocarcinoma arising from a benign cystic mucoid lesion compatible with bronchogenic cyst. Immunohistochemical staining was positive for cytokinin 20 and CDX 2, and negative for cytokinin 20 and TTF1. Mediastinal lymph nodes were not affected.. The final diagnosis was enteric adenocarcinoma arising from a bronchogenic cyst. No additional lesions were found on colonoscopy and further abdominal exams.

A bronchogenic cyst is congenital malformation of the foregut which was generally encountered within the mediastinum and detected in pediatric patients with symptoms of infection or compression on vital structures. They are rarely detected in adult population as a neck mass. We have recently experienced one case of bronchogenic cyst as a parathyroid mass in a 50-year-old female. It was incidentally detected by routine neck ultrasonography and interpreted as a parathyroid cyst with hemorrhage preoperatively, but confirmed as a bronchogenic cyst at pathologic examination. We report this case with review of literatures ...
