Electromagnetic navigational bronchoscopy with dye marking for identification of small peripheral lung nodules during minimally invasive surgical resection
Benign metastasising leiomyoma (BML) is characterised by extrauterine smooth muscle tumours in women after surgical treatment for uterine leiomyoma. Usually manifested as solitary or multiple focal lesions in various organs, it imposes a scrutinous diagnostic work-up to exclude a malignant disease and requires confirmation in microscopic examination of the extrauterine focus.. The authors present a case of a 56-year-old woman with BML manifesting as bilateral multiple pulmonary nodules, with a tentative diagnosis of a disseminated malignant disease of mesenchymal origin.. The patient underwent multiple diagnostic tests, which excluded malignancy. The definite diagnosis was established after the microscopic reevaluation of an excised pulmonary nodule. The patient is monitored with chest magnetic resonance. BML should be considered in the differential diagnosis of multiple pulmonary nodules in asymptomatic women. Patients with BML require long-term monitoring, therefore the selected imaging method ...
A number of small lung lesions characterized by small round masses of 2- to 3-mm in diameter. They are usually detected by chest CT scans (COMPUTED TOMOGRAPHY, X-RAY). Such nodules can be associated with metastases of malignancies inside or outside the lung, benign granulomas, or other lesions ...

This 70 year-old gentleman presented to our facility May 23, 2011 with a history of bladder cancer in 2005. Surgical removal of tumors was the only form of management the patient received for this diagnosis. More recently, the patient had CT scans dated February 25 and March 26, 2011 which revealed extensive mediastinal adenopathy, a hypermetabolic mass in the anterior segment of the right upper lobe, and multiple pulmonary nodules. Also present on the March 26 scan was moderately intense tracer uptake involving the medial margin of the left ninth rib. A CT core guided biopsy performed 4/21/2011 concluded a diagnosis of "poorly differentiated carcinoma" which was determined to be, "consistent with primary carcinoma of the lung." The patient had smoked throughout his life, and while he had reduced his intake, he did not quit despite encouragement to.. Read more ,,. ...

A gynaecological examination was performed and multiple uterine leiomyomas were found. A clinical-functional-radiological follow-up was planned. No further treatment was prescribed and the residual nodules have not increased in size during the 18 months of follow-up. The patient remains well and without pulmonary symptoms.. The aetiology of multiple pulmonary nodules is quite complex, with metastatic disease being the most common cause. Other possibilities include sarcoidosis or an inflammatory process, such as fungus, tuberculosis, nocardiosis or septic emboli. However, in asymptomatic patients, further considerations include the presence of rheumatoid nodules, amyloidosis and arteriovenous malformations. The possibility of even less common lesions, including hamartomas and smooth muscle tumours such as leiomyomas, also exists [1]. BML is a rare disorder with ∼100 cases reported in the literature. It affects females who have previously undergone hysterectomies or myomectomies due to ...
Pulmonary nodules or lung nodules are small round or oval shaped growth in the lung. It is also called spot on lung or coin lesion. Most nodules are small 1 to 1.2 inches in diameter. Larger nodules are called lung mass.. Nodule could be malignant (cancer) versus benign (noncancerous). Over 90% small pulmonary nodule are benign. Benign nodule could be ascar from prior infection, granulomas, infection and other conditions. Malignant nodules include primary lung cancer, lymphoma, carcinoid, sarcoma and metastatic nodules- tumors that have spread to lung from cancer in another body part.. Most nodules are asymptomatic and usually found on CXR or CT chest done for some other reasons. Larger lung mass can cause chest pain, cough, hemoptysis. Benign small nodules are commonly seen on CT chest. Usual test done during workup includes chest X-ray, CTchest, and PET scan. If thenodule is large or growing on serial CT chest, abiopsy is recommended or complete removal by thoracoscopic surgery. A biopsy can ...
Solitary pulmonary nodule (SPN) is a diagnostic challenge for both radiologists and physicians. There have been numerous common and uncommon causes of SPN. We report a30-year-old Indian man with pulmonary thromboembolism, where the pulmonary thrombus was seen as a SPN on the chest radiograph. To the best of our knowledge, this observation has not been published in the literature..

A solitary pulmonary nodule (SPN) or coin lesion is a mass in the lung smaller than 3 centimeters in diameter. It can be an incidental finding found in up to 0.2% of chest X-rays and around 1% of CT scans. The nodule most commonly represents a benign tumor such as a granuloma or hamartoma, but in around 20% of cases it represents a malignant cancer, especially in older adults and smokers. Conversely, 10 to 20% of patients with lung cancer are diagnosed in this way. If the patient has a history of smoking or the nodule is growing the possibility of cancer may need to be excluded through further radiological studies and interventions, possibly including surgical resection. The prognosis depends on the underlying condition. Nodular density is used to distinguished larger lung tumors, smaller infiltrates or masses with other accompanying characteristics. An often used formal radiological definition is the following: a single lesion in the lung completely surrounded by lung parenchyma (functional ...
Picture the scene: a lung cancer multidisciplinary team (MDT) meeting, somewhere in the UK, January 2015. CT images from a patient with suspected colorectal cancer, whom no one present has ever met, are discussed at the request of the colorectal team. An abnormality is present in the right lower lobe of lung. A week earlier, following two clicks and a drag from the colorectal radiologists mouse, a 5 mm incidental pulmonary nodule was identified and is now destined to take its unwitting host on an unpredictable journey, which may span years. Imperfectly remembered advice from multiple professional society guidelines, some a decade old, will be proffered and contested in repeated meetings. How should the nodule be measured, how often, by whom? What is the risk that it is malignant? Is now (ever?) the right time for a biopsy? This scenario, which is likely familiar to many readers, has often served to relegate nodule follow-up to a tedious chore shared widely to ease the burden.. Help is at hand. ...

Background: The discovery of a solitary pulmonary nodule (SPN) on a chest imaging exam is of major clinical concern. However, the incidence rates of SPNs in a general population have not been estimated. The objective of this study was to provide incidence estimates of SPNs in a general population in 5 northeastern regions of France. Methods: This population-based study was undertaken in 5 regions of northeastern France in May 2002-March 2003 and May 2004-June 2005. SPNs were identified by chest CT reports collected from all radiology centres in the study area by trained readers using a standardised procedure. All reports for patients at least 18 years old, without a previous history of cancer and showing an SPN between 1 and 3 cm, were included. Results: A total of 11,705 and 20,075 chest CT reports were collected for the 2002-2003 and 2004-2005 periods, respectively. Among them, 154 and 297 reports showing a SPN were included, respectively for each period. The age-standardised incidence rate (IR)

PURPOSE: The evaluation of pulmonary nodules constitutes a large part of PET-CT studies. In this study, we aimed to evaluate the different interpretation criteria in F-fluorodeoxyglucose PET attenuation-corrected and non-attenuation-corrected studies as individual predictors of malignancy in order to propose a useful combination of criteria that can be used in daily practice to classify nodules appropriately. PATIENTS AND METHODS: We performed a historical prospective survey of all consecutive patients referred to our service for the initial assessment of pulmonary nodules and sought the final characterization of these nodules either from tissue sampling or from radiological and clinical follow-up ...
Background: There is a wide range of tools used in diagnosis of pulmonary nodules localized beyond the range of standard bronchfiberoscope, but is still difficult to choose best method to obtain tissue samples.. Aims and objectives: The aim of our study was to asses safety and utility of methods currently used in Department of Pulmonology in Katowice, Poland, and on the basis of obtained results to prepare diagnostic protocol to be tested in prospective study.. Methods: 93 consecutive patients records (56 females and 37 makes) were analyzed. Included patients had at least one pulmonary nodule exceeding 10 mm in diameter, which on the basis of CT scan was not assessable by standard bronchofiberoscope.. Results: 64 transthoracic biopsies were performed: 40 CT-guided cytological [22 (55%) diagnostic], 20 ultrasound guided cytological [10 (50%) diagnostic] and 4 ultrasound guided histological [all diagnostic] respectively. Pleural fluid was examined 8 times but only one pleurocentesis was ...

RESULTS: MAD2 was found both in SCLC and NSCLC. Interestingly, there was a significant difference found between SCLC and NSCLC using qt-PCR (P,0.05). The area under the ROC curve of MAD2 expression was 0.799, with medium diagnostic value. MAD2 expression was related to age, lymphatic metastasis, and survival time, but not with sex. The positivity for MSA and ACA by IIF assay were 37.20% and 34.00%, respectively, in the SCLC group, which were higher than in the NSCLC and pulmonary nodule groups (P,0.05). The kappa values of MSA and ACA with MAD2 expression were 0.73 and 0.65, respectively, with moderate consistency. Combining MAD2 with MSA and ACA enhanced the sensitivity and specificity for diagnosing SCLC ...
An automated method for analyzing a nodule and a computer storage medium storing computer instructions by which the method can be implemented when the instructions are loaded into a computer to program the computer. The method includes obtaining a digital image including the nodule; segmenting the nodule to obtain an outline of the nodule, including generating a difference image from chest image, identifying image intensity contour lines representative of respective image intensities in a region of interest including the nodule, and obtaining an outline of the nodule based on the image intensity contours; extracting features of the nodule based on the outline; applying features including the extracted features to at least one image classifier; and determining a likelihood of malignancy of the nodule based on the output of the at least one classifier. In one embodiment, extracted features are applied to a linear discriminant analyzer and/or an artificial neural network analyzer, the outputs of
A multidisciplinary writing committee comprising four pulmonologists, two thoracic surgeons, and one radiologist developed or revised recommendations, rated the quality of evidence, and graded the strength of the recommendations by using a standardized approach. The writing committee reviewed all recommendations and reached consensus by iterative discussion and debate. The manuscript was extensively revised, although some sections of text (including much of the section on solid nodules measuring ≤8 mm in diameter) were considered to be current and, therefore, retained from the previous version.. Panel Composition and Responsibilities. A call for applications to serve on the 3rd edition of the American College of Chest Physicians (ACCP) Lung Cancer Guidelines (LC III) panel was put forth to the ACCP membership, to past panelists, and to other organizations that have previously endorsed earlier editions of these guidelines or appointed representatives to serve on those panels.

BACKGROUND: The new technique chest tomosynthesis refers to the principle of collecting low-dose projections of the chest at different angles and using these projections to reconstruct section images of the chest at a radiation dose comparable to that of chest radiography. PURPOSE: To investigate if, for experienced thoracic radiologists, the detectability of pulmonary nodules obtained after only a short initial learning period of chest tomosynthesis improves with additional clinical experience of the new technique. MATERIAL AND METHODS: Two readings of the same clinical chest tomosynthesis cases, the first performed after 6 months of clinical experience and the second after an additional period of 1 year, were conducted. Three senior thoracic radiologists, with more than 20 years of experience of chest radiography, acted as observers, with the task of detecting pulmonary nodules in a jackknife free-response receiver operating characteristics (JAFROC1) study. The image material consisted of 42 ...

The patient was referred to the clinic for further evaluation eight days after surgery, with a view to undertaking possible post-operative adjuvant treatment. Following admission to hospital, a computed tomography (CT) scan of the neck and thorax was performed for staging and treatment planning purposes. The study revealed a heterogeneous and diffuse, contrast-enhancing soft tissue opacity in the subcutis of the left ventral neck, compatible with scar healing tissue. The left thyroid gland was not present. The measurements of the regional lymph nodes were within normal limits. A 2-mm nodule of soft tissue opacity was observed at the ventral aspect of the left cranial lung lobe. The rest of the thoracic study revealed no marked abnormalities. Owing to the very small size of the unique pulmonary nodule, no sample could be taken for analysis and its differential diagnosis included both benign (inflammation or granuloma) or malignant (primary or secondary) processes.. Following the CT scan it was ...

Early and automatic detection of pulmonary nodules from CT lung screening is the prerequisite for precise management of lung cancer. However, a large number of false positives appear in order to increase the sensitivity, especially for detecting micro-nodules (diameter | 3 mm), which increases the radiologists workload and causes unnecessary anxiety for the patients. To decrease the false positive rate, we propose to use CNN models to discriminate between pulmonary micro-nodules and non-nodules from CT image patches. A total of 13,179 micro-nodules and 21,315 non-nodules marked by radiologists are extracted with three different patch sizes (16 × 16, 32 × 32 and 64 × 64) from LIDC/IDRI database and used in the experiments. Three CNN models with different depths (1, 2 or 4 convolutional layers) are designed; their performances are evaluated by the fivefold cross-validation in term of the accuracy, area under the curve (AUC), F-score and sensitivity. The network parameters are also optimized. It is

Very sorry for the necessity that drew you here. This link is compiled by the Am Cancer Soc and its pretty comprehensive. Print it out. There is room to write the answers if you print it out. If possible, have someone come with you to take notes. If you miss something or dont quite understand what they say, ask them to repeat it in plain English. If you think of it after the appt, dont worry. Call the office back with the question. The drs. nurse will call back with the info. If you have to have lung cancer, this is the slowest growing cancer which is fairly good news. There are fewer options for treatment at this time but with the advent of the newer targeted therapies in clinical trial, chances are very good that they will have several options in use before you need it. If they recommend lobectomies or wedges or both, you may never need further intervention. This may be overwhelming at first, but, it is survivable. Please let us know what the drs say.

RPOSE: In this study, an automated scheme for detecting pulmonary nodules using a novel hybrid PET/CT approach is proposed, which is designed to detect pulmonary nodules by combining data from both sets of images.METHODS: Solitary nodules were detected on CT by a cylindrical filter that we developed previously, and in the PET imaging, high-uptake regions were detected automatically using thresholding based on standardized uptake values along with false-positive reduction by means of the anatomical information obtained from the CT images. Initial candidate nodules were identified by combining the results. False positives among the initial candidates were eliminated by a rule-based classifier and three support vector machines on the basis of the characteristic features obtained from CT and PET images.RESULTS: We validated the proposed method using 100 cases of PET/CT images that were obtained during a cancer-screening program. The detection performance was assessed by free-response receiver ...
