TY - JOUR. T1 - Congestive Heart Failure Due to Giant Cutaneous Cavernous Hemangioma. AU - Howell, David M.. AU - Gumbiner, Carl H.. AU - Martin, Gladys E.O.. PY - 1984/9. Y1 - 1984/9. N2 - A female infant is presented with isolated giant cutaneous cavernous hemangioma with secondary severe congestive heart failure. Studies to identify other major arteriovenous malformations were negative. An attempt to treat the patient with a corticosteroid was not successful in reducing the size of the hemangioma. She required an aggressive anticongestive medical regimen for 2 years. Though not previously described, high output congestive heart failure can occur secondary to isolated cutaneous hemangioma. Aggressive medical management may alleviate the need for the increased risk of surgical or other therapeutic approaches in this often self-limited condition..

|p| Hemangiomas are benign tumors originating in the vascular tissues of skin, mucosa, muscles, glands, and bones. Although these tumors are common lesions of the head and neck, they rarely occur in the nasal cavity and paranasal sinuses. Cavernous haemangioma of the lateral wall of the nasopharynx has not previously been reported. We examined the clinical, radiological and therapeutic management of cavernous haemangioma of nasopharynx starting from a clinical case of a 26-year-old woman with a history of recurrent and conspicuous epistaxis and leftsided nasal associated severe obstruction. Nasopharynx examination, by flexible endoscopy, showed a cystic mass borne by the left side wall of the nasopharynx, in contact with the soft palate, covered by intact and regular mucosa. Contrast-enhanced computed tomography (CT) scan, confirmed these findings and showed contextual lamellar calcifications and inhomogeneous enhancement. The nasal endoscopic approach (FESS), under general anesthesia, allowed removal

Herein, we described the clinical, pathological, and imaging features of five patients with HSH. Interestingly, the ADCmean values had a different pattern between HSH and malignant liver metastases; however, the ADCmean values were similar in the degenerate and non-degenerate areas of HSH. To the best of our knowledge, the current study is the first report to mention the differences of ADCmean values between the degenerate and non-degenerate areas in HSH.. Cavernous hemangioma is the most common hepatic vascular tumor in adults [9], while HSH is an extremely rare liver tumor [1]. HSH has various degenerative changes such as extensive fibrosis with subsequent hyalinization, marked narrowing or obliteration of the vascular spaces, and hemorrhage or sclerosis [10]. Makhlouf and Ishak compared the findings of HSH and cavernous hemangioma in terms of pathology. Compared with cavernous hemangioma, HSH contained abundance of collagenous tissue and elastic fibers around and between small sclerotic ...

BACKGROUND/AIMS Sclerosed hemangiomas of the liver are rare. To date, their histopathology, immunohistochemistry, and the role of mast cells (MC) in their histogenesis have not been systematically studied. PATIENTS/METHODS Clinical, histopathologic and immunohistochemical features of 20 sclerosed hemangiomas were compared with those of 18 sclerosing cavernous hemangiomas. The number of MC was quantified and compared in all cases, using a tryptase immunostain. RESULTS Compared to patients with sclerosed hemangiomas, those with sclerosing hemangiomas were younger (mean age, 63 versus 71 years); had larger tumors (mean 6 +/- 4.73 versus 3 +/- 2.2 cm); presented with a mass more frequently, and epigastric pain less frequently. Sclerosing hemangiomas, but not sclerosed hemangiomas, were more frequent in males than in females. Sclerosing hemangiomas occurred much more frequently in the right lobe than sclerosed hemangiomas. Sclerosing hemangiomas had less fibrosis, hyalinization, and elastic fibers than

Cavernous hemangioma is the most common benign orbital tumor found in adults. Hemangiomas are usually present at birth, although they may appear within a few months after birth, often beginning at a site that has appeared slightly dusky or differently colored than the surrounding tissue. Most of these tumefactions are exceedingly unilateral. Although cavernous hemangiomas are histologically benign, they can encroach on intraorbital or adjacent structures and can be considered anatomically or positionally malignant. Visual acuity or field compromise, diplopia, and extraocular muscle or pupillary dysfunction can result from compression of intraorbital contents by the angioma. Hemangiomas may be present anywhere on the body. However, they are most disturbing to parents when they are on the infants face or head. Hemangiomas of the eyelid may interfere with the development of normal vision and must be treated in the first few months of life. Large cavernous hemangiomas may develop secondary ...

OBJECTIVE To report the occurrence of an orbital schwannoma probably arising from the optic nerve sheath. PATIENT AND METHOD Clinical case report. RESULTS A 65-year-old patient presented with a painless, progressive right proptosis over five years. Magnetic resonance imaging revealed an intraconal mass, radiographically consistent with a cavernous hemangioma. Surgical resection was performed and pathology disclosed a schwannoma affecting the optic nerve. The optic nerve, which does not contain Schwann cells, is exceptionally rarely affected by Schwannomas, which may arise from a few sympathetic nerve fibers or from a few ectopic cells, not normally present within the optic nerve. CONCLUSION The radiologic appearance of the very rare optic nerve Schwannoma may be confused with a cavernous hemangioma, a more common tumor in this location.
These images are from a 26 year old woman, with a 10 year history of headache and a recent onset of progressive right arm and leg weakness, who underwent radiosurgery. SPECT images were made with Technetium labeled red blood cells. On the MR, several angiomas are seen, e.g., in the left pons and right cerebellum, as regions of mixed MR signal, suggesting that the lesions are a complex mix of tissue elements such as blood clot and scarred brain, surrounded by a halo of a crystallized old blood product, hemosiderin. These lesions fail to fill with labeled red cells, indicating that they are not open to circulating blood. Note the cerebral vessels filling with Tc-labeled red cells. In slice 9, look for the internal carotid arteries and the sigmoid and straight sinuses, comparing the MR flow voids to the Tc-labeled red cells.. ...
In the past, the investigators often treated giant cavernous hemangiomas of the liver by hepatectomy.Recently RFA and laparoscopic hepatectomy are also available and could be applied to cure this disease.But we cant get a clear answer about their effectiveness and safety.

BACKGROUND Cerebral cavernous angiomas (CAs) with a symptomatic hemorrhage (CASH) have a high risk of recurrent hemorrhage and serious morbidity.METHODS Eighteen plasma molecules with mechanistic roles in CA pathobiology were investigated in 114 patients and 12 healthy subjects. The diagnostic biomarker of a CASH in the prior year was derived as that minimizing the Akaike information criterion and validated using machine learning, and was compared with the prognostic CASH biomarker predicting bleeding in the subsequent year. Biomarkers were longitudinally followed in a subset of cases. The biomarkers were queried in the lesional neurovascular unit (NVU) transcriptome and in plasma miRNAs from CASH and non-CASH patients.RESULTS The diagnostic CASH biomarker included a weighted combination of soluble CD14 (sCD14), VEGF, C-reactive protein (CRP), and IL-10 distinguishing CASH patients with 76% sensitivity and 80% specificity (P = 0.0003). The prognostic CASH biomarker (sCD14, VEGF, IL-1β, and ...

Cavernous hemangioma, also called cavernous angioma, cavernoma, or cerebral cavernous malformation (CCM) (when referring to presence in the brain) is a type of blood vessel malformation or hemangioma, where a collection of dilated blood vessels form a benign tumor. Because of this malformation, blood flow through the cavities, or caverns, is slow. Additionally, the cells that form the vessels do not form the necessary junctions with surrounding cells. Also, the structural support from the smooth muscle is hindered, causing leakage into the surrounding tissue. It is the leakage of blood, known as a hemorrhage from these vessels that causes a variety of symptoms known to be associated with this disease.Wikipedia Familial CCM is inherited in an autosomal dominant manner, generally based on heterozygous mutations in the KRIT1, CCM2, or PDCD10 genes (defining the CCM1, CCM2 and CCM3 phenotypes, respectively).GeneReviews In the US, a nonprofit involved in supporting cavernous angioma research and ...
Atopic myelitis, a type of myelitis which appears in patients with elevated serum levels of immunoglobulin E (IgE), occurs more commonly in the cervical spinal cord, but this mechanism has not yet been elucidated. Herein, we experienced a case of atopic myelitis developed during the growth of cervical cavernous angioma caused by bleeding. A 37-year-old woman suffered from hand swelling caused by a house cat licking. At the same time when cavernous angioma had grown, she experienced a numbness in her four extremities, and multifocal peritumoral hyperintense spinal cord signals were seen. The diagnosis of atopic myelitis was made because we observed significantly elevated levels of specific IgE antibody to cat dander. Symptoms disappeared immediately after steroid pulse therapy. We subsequently resected a cavernous angioma, and eosinophil invasion was found inside it. This is the first case report of atopic myelitis which developed in association with spinal cord vascular lesions. A local ...
Asha has Kasabach-Merritt syndrome with a large cavernous hemangioma of her left thigh since she was born.. In March 1976, she fell and sustained a pathological fracture of the left femur. She sustained a second fracture in October 1976 after having a fall. During this interim period, she was prescribed with a knee ankle foot orthosis. The fracture healed reasonably well again.. In 1977, she had an arteriogram performed which revealed the presence of a large hemangioma extending from the perineum right down to the left knee joint. In October 1978, she sustained a third fracture which associated with narrowing of the femur. This fracture did not heal despite immobilization, intramedullary nailing and bone graft. She was left with significant leg length discrepancy of approximately 14 cm. As a result of these complications, her left knee became ankylosed and she had difficulty with ambulation. During this period, she was fitted with above knee extension prosthesis, with quadralateral socket, ...
Cavernous hepatic hemangiomas are benign liver tumors and present as incidental findings on sonographic examinations, but little is known concerning their natural course. Therefore, we performed a clinical and imaging follow-up of 64 cases of cavernous hepatic hemangioma in 50 patients during an average 18.8 month period. One case presented a symptom of slightly right upper quadrant pain and two cases showed thrombocytopenia. In one of the thrombocytopenia cases, cavernous hepatic hemangioma was resected because of Kasabach-Merrit syndrome. No case increased in size during follow-up, but one case decreased and disappeared. These results suggested that prolonged clinical and imaging follow-up of cavernous hepatic hemangiomas may be needed ...

Portal vein thrombosis (PVT) is classified into acute and chronic types. Acute portal vein thrombosis presents within 60 days with symptoms like abdominal pain or distention, diarrhea, nausea, vomiting, anorexia and fever with absence of portal carvernoma and portal hypertension. Chronic PVT is mostly asymptomatic and associated with portal cavernoma and/or complications of portal hypertension. PVT is also classified into complete and partial types, and each is subclassified based on the presence or absence of portal cavernoma. Patients with complete PVT have higher frequency of cavernous transformation than those with partial PVT. The common causes of PVT include cirrhosis, neoplasm, myeloproliferative disorders, inflammatory disorders like pancreatitis and thrombophilias. PVT is a relatively common complication of liver cirrhosis. With the stoppage of the portal venous blood flow, there is a compensatory mechanism of venous rescue due to rapid development of collaterals to bypass the ...
About Hemangioma of Infancy. Hemangioma of infancy,caused by a proliferation of endothelial cells (which line blood vessels), is the most common tumor of infancy. Hemangioma of infancy ranges in color from red to purple, and are soft and compressible. Lesions are usually solitary, favoring the head and neck. Girls are affected more often than boys. Hemangioma of infancy is not present at birth but appears postnatally.. Hemangioma of infancy goes through three stages: proliferation, involution, and involuted. The proliferation stage usually occurs during the first year of life, during which the hemangioma can enlarge rapidly. The hemangioma then gradually involutes over the two to six years, and is usually completely involuted by the fifth year. Ulceration may occur in the course of regression. Hemangioma of infancy usually resolves without scarring, but atrophy, depigmentation and scarring sometimes occur.. Variations of hemangioma of infancy include deep hemangioma, multiple hemangiomas of ...

A hemangioma is a noncancerous clumping of blood vessels found on the skin or internal organs, most commonly the liver. Hemangiomas are often present at birth or develop in the first few months of life. Skin hemangiomas are quite common, mostly found on the face and neck. Liver hemangiomas rarely cause symptoms. Cavernous hemangiomas most commonly form on the brain or spinal cord and have a different outcome than the other types of hemangiomas. The cause of the clumping of the blood vessels is not well understood.. Skin hemangiomas form on the surface of the skin or in the fatty layer just underneath. It may at first appear as a flat birth mark, but will become a raised red rubbery or spongy lump over the first year. Most will stop growing at this point and after some time will begin to go away. Most skin hemangiomas disappear by age 10, though a faint discoloration may remain. Hemangiomas may affect the vision if they are on the eyelid. Liver hemangiomas can form within the organ or on its ...
Central Nervous System Venous Angioma: A vascular anomaly characterized by a radial or wedge-shaped arrangement of dilated VEINS draining into a larger vein in the brain, spinal cord, or the meninges. Veins in a venous angioma are surrounded by normal nervous tissue, unlike a CENTRAL NERVOUS SYSTEM CAVERNOUS HEMANGIOMA that lacks intervening nervous tissue. Drainage of venous angioma is fully integrated with the bodys venous system, therefore, in most cases there is no clinical signs and rare bleeding.

At that time I was a student at the University of California. After the bleed, I remember going to a lecture and seeing on my peripheral gaze a light flickering (I had experienced strange ocular disturbances prior to my bleed.) Following the talk, I went and examined the light. The flickering was caused by a faulty fluorescent tube. There is a moral to this story I thought.. The bleed from my cavernoma left me with four symptoms.. • Holmes tremor affecting my right side. • Dysarthria - ...
