1/9. Cavernous angioma of the internal acoustic meatus--case report.A 39-year-old female presented with an intrameatal cavernous angioma manifesting as hearing loss and tinnitus in the right ear which progressed over 8 months. Magnetic resonance (MR) images revealed an intrameatal lesion as ultra-high intensity, nearly as bright as cerebrospinal fluid, on the T2-weighted images, and isointensity on the T1-weighted images. Computed tomography (CT) showed the mass accompanied by stippled patterns of calcification. The patient underwent surgery under a diagnosis of calcified acoustic neurinoma. Histological studies were compatible with cavernous angioma. Intrameatal cavernous angioma is a rare disease which requires differential diagnosis from the more common neurinoma or meningioma in this location. Intrameatal lesion with ultra-high intensity on T2-weighted MR imaging and stippled patterns of calcification on CT is more likely to be cavernous angioma than acoustic neurinoma. These neuroimaging features are important information in deciding the treatment strategy.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
2/9. Diffuse hepatic hemangiomatosis in an adult.Diffuse hepatic hemangiomatosis without extrahepatic lesions is extremely rare in adults. A case of diffuse hepatic hemangiomatosis involving right lobe in a 50-year-old woman was presented. The hemangiomatosis was demonstrated by ultrasonography, computerized tomography (CT) and magnetic resonance image (MRI), and was confirmed histopathologically. Although diffuse hepatic hemangiomatosis is a rare disease in adults, its diagnosis should be considered in patients with diffuse tumor growth in one or both hepatic lobes and distinguished from malignant tumors. The present case is the first documented case of diffuse hepatic hemangiomatosis in an adult in korea.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
3/9. Cavernous hemangioma of the rib.A 59-year-old man with an enlarged left chest wall mass that had been followed up for 3 years underwent surgical resection. The mass was pathologically diagnosed as cavernous hemangioma of the rib. This is the fourth case of this rare disease to be reported. However, it suggests that hemangioma of the rib should be considered in the differential diagnosis of rib tumors, especially in asymptomatic patients.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
4/9. Diffuse cavernous hemangioma of the rectum: an atypical cause of rectal bleeding.OBJECTIVE: cavernous hemangioma of the rectosigmoid colon is a rare disease, with no more than 200 cases reported in the literature. The rectosigmoid is the most common site of this disease in the gastrointestinal tract. CASE REPORT: we report the case of a 31-year-old male with recurrent episodes of rectal bleeding, who was finally diagnosed of diffuse cavernous hemangioma of the rectum. The tumor, of 12 x 10 x 9 cm in size, occupied the rectum to the margin of the anal sphincter. A surgical procedure was ruled out because of the inability to carry out a safe anastomosis while preserving anal sphincters. DISCUSSION: rectal hemangiomas are less frequent vascular malformations. The clinical presentation of a cavernous hemangioma of the rectum is usually acute, recurrent or chronic rectal bleeding. Other symptoms stem from the possible compression or invasion of adjacent structures, such as lumbar or perianal pain, metrorrhage, hematuria, etc. This diagnosis is commonly made in younger patients. colonoscopy is without doubt the diagnostic technique of choice, and it allows to establish the localization, morphology, and total extension of the lesion; its characteristic image is a red-purplish nodule with great vascular congestion. According to the opinion of most authors, biopsy is not advisable during colonoscopy, since imaging techniques are sufficient for an accurate diagnosis, and the risk of bleeding while manipulating this lesion is not negligible. Computed tomography and particularly magnetic resonance imaging, given their high precision to delimit the lesion and its relations to adjacent structures, are imaging studies that are mandatory before surgical treatment. Other techniques such as selective angiography, barium enema, gastrointestinal transit, and upper-tract endoscopy may be supplementary and help locate more lesions along the gastrointestinal tract. Failure to recognize the exact diagnosis and extent of diffuse cavernous hemangioma may lead to failed surgical treatment and severe complications. Complete surgical excision of the lesion with a sphincter-saving procedure is the primary mode of treatment: conservative proctectomy with coloanal anastomosis.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
5/9. Cavernous hemangioma of the skull presenting with subdural hematoma. Case report.Cavernous hemangioma of the calvaria is a very rare disease, and patients usually present with headaches or a visible skull deformity. Few reports of patients presenting with intradiploic or epidural hemorrhages are found in the literature. No case of an intradural hemorrhage from a cavernous hemangioma of the skull has been reported to date. The authors present the case of a 50-year-old man in whom a symptomatic subdural hematoma (SDH) resulting from a cavernous hemangioma of the calvaria had hemorrhaged and eroded through the inner table of the skull and dura mater. The patient underwent surgery for evacuation of the SDH and resection of the calvarial lesion. Postoperatively, the patient experienced immediate relief of his symptoms and had no clinical or radiological recurrence. Calvarial cavernous hemangiomas should be considered in the differential diagnosis of nontraumatic SDHs. Additionally, skull lesions that present with intracranial hemorrhages must be identified and resected at the time of hematoma evacuation to prevent recurrences.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
6/9. Successful removal of a slowly growing mediastinal cavernous haemangioma after vascular embolization.Mediastinal haemangioma is a rare disease. We report a 23-year-old male patient with a posterior mediastinal cavernous haemangioma. The CXR revealed a progressively enlarging mediastinal mass which on chest CT and angiography appeared to be a well-enhanced hypervascular tumour. Angiographic gel foam embolization of the feeding vessels was undertaken prior to the surgical removal of the mass. The mass lesion following surgical removal was shown to be a cavernous haemangioma on histological examination.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
7/9. third ventricle cavernous angioma: report of two cases.Cavernous angioma arising in the third ventricle is an extremely rare disease. We have reviewed five cases previously reported, as well as our own two cases, and discuss the clinical characteristics of and surgical approach to cavernous angioma at this site. The bifrontal craniotomy and interhemispheric translamina terminalis approach minimize the damage to the brain and allow for an approach to the third ventricle in a wide operative field with minimal compression of the brain itself. We have found this approach to be suitable for surgery on angiomas of the anterior half of the third ventricle.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
8/9. hemangioma of the small bowel. Case report.Cavernous hemangioma is a very rare disease if located in the ileum, but not an uncommon lesion if it occurs in the large bowel. The Authors report a case of small bowel cavernous hemangioma, and consider clinical, diagnostic and therapeutic aspects for an exact evaluation of the lesion.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
9/9. Gastrointestinal bleeding and paraparesis in blue rubber bleb nevus syndrome.Blue rubber bleb nevus syndrome (BRBNS), which consists of cutaneous and visceral hemangiomas, is a rare disease. Complications such as gastrointestinal (GI) bleeding, anemia and coagulopathy have been documented. We report a patient with BRBNS who presented with acute paraparesis in addition to GI bleeding and coagulopathy.- - - - - - - - - - ranking = 1keywords = rare disease (Clic here for more details about this article) |
