1/38. Haemangioma of bone with radiographic appearances simulating a giant cell tumour.A case is described of haemangioma of the proximal end of the humerus which simulated a giant cell tumour on radiography. An attempt at biopsy, carried out elsewhere, had failed because of severe haemorrhage from the tumour during operation. It was treated by en bloc resection and endoprosthesis with a good result after one year.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
2/38. A case of intra-abdominal multiple lymphangiomas in an adult in whom the immunological evaluation supported the diagnosis.A 60-year-old patient with intra-abdominal lymphangiomatosis is described. He presented with anaemia due to enteric haemorrhage, hypoproteinaemia with heavy hypogammaglobulinaemia and T-cell lymphopenia. Duodenal biopsy showed lymphangiectasia while a small bowel study revealed several filling defects in the terminal ileum. On exploratory laparotomy, numerous inoperable lymphangio-haemangiomata were found, involving the small and large intestine, appendix, mesenterium, gallbladder and main biliary tract. The importance of T-cell lymphopenia and hypogammaglobulinaemia in the diagnosis of intra-abdominal lymphangiomatosis with lymphangiectasia is stressed.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
3/38. Cavernous haemangioma of the retina and optic disc. A report of three cases and a review of the literature.We report characteristics of three cases of cavernous haemangioma of the retina, bringing to 37 the number now reported in the available literature. This rare, benign, congenital malformation is non-progressive, usually unilateral, somewhat more frequent in women, and rarely a source of intraocular haemorrhage. The fluorescein angiographic features include a normal arterial and venous supply, extraordinarily slowed venous drainage, no arterio-venous shunting, no disturbances of vascular permeability, and no secondary retinal exudation. Almost always, isolated clusters of vascular globules with plasma/erythrocyte sedimentation surround the main body of the malformation. These findings differentiate the anomaly from other retinal vascular diseases. Therapeutic intervention is seldom necessary.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
4/38. Blue rubber bleb nevus syndrome and gastrointestinal haemorrhage: which treatment?PURPOSE: To describe a paediatric case of "Blue rubber Bleb nevus syndrome" (BRBNS) or Bean's syndrome, a rare systemic disorder characterised by cutaneous and gastrointestinal vascular malformations that often lead to overt life-threatening gastrointestinal bleeding or occult blood loss with severe anaemia and iron deficiency. CASE REPORT: A 6-year-old girl with multiple characteristic cutaneous vascular lesions was admitted for a massive rectal bleeding. A few months previously she was endoscopically treated for gastric angiomas which developed into melaena. Preoperative investigations revealed the recurrence of gastric lesions. At laparotomy, more than 25 angiomas of the GI tract were found. Multiple intestinal resections were carried out. RESULTS: No intraoperative or postoperative problems occurred and the girl is completely healthy without further bleeding after a follow-up period of three years. CONCLUSIONS: BRBNS belongs to the group of vascular venous malformations. Most of the time it occurs sporadically, but it can be inherited as an autosomal dominant trait. Recent analysis identified a locus on chromosome 9 responsible for venous malformations. BRBNS patients present typical skin lesions, with some lesions having a rubber-like nipple appearance; the number of skin and GI lesions and the severity of anaemia are correlated. Treatment is dependent on the extent of gut involvement and the severity of the clinical picture. In the absence of massive bleeding, a conservative treatment will be sufficient; otherwise resections are mandatory, but additional lesions may subsequently develop. Management with electrocautery or laser photocoagulation are usually not effective even if some reports recommend them. Pharmacological treatment is useless. prognosis of BRBNS is unknown.- - - - - - - - - - ranking = 8.1123005518725keywords = gastrointestinal haemorrhage, haemorrhage (Clic here for more details about this article) |
5/38. life-threatening haemorrhage as a complication of a congenital haemangioma.life-threatening complications of congenital haemangiomas are rare. A case of haemorrhage in a neonate is reported here. A neonate presented a congenital haemangioma of the limb complicated by a massive life-threatening haemorrhage. Colour ultrasonography showed a hypervascularized, highly haemodynamically active mass with a large, superficial drainage vein just under the ulceration. Surgical resection was performed with satisfactory postoperative outcome and no evidence of recurrence. CONCLUSION: Early surgical removal can be a good therapeutic option for complicated congenital haemangiomas.- - - - - - - - - - ranking = 6keywords = haemorrhage (Clic here for more details about this article) |
6/38. Papillary endothelial hyperplasia within synovial haemangioma of the flexor tendon sheath of the wrist.A 60-year-old housewife presented with a painful and slowly enlarging swelling in the left wrist for 3 months. Plain X-ray showed mild soft tissue swelling and ultrasonography tenosynovitis of the flexor tendons. Exploration revealed a vascular growth involving the synovium of the flexor tendon sheath of the left little finger. Synovectomy and excision of the entire growth led to the diagnosis of synovial haemangioma with areas of recent haemorrhage and florid papillary endothelial hyperplasia. The recent haemorrhage corresponded to the sudden increase in size, while the papillary endothelial hyperplasia accounted for the persistence and gradual enlargement of the lesion. The patient made an uneventful recovery and remained well more than 2 1/2 years after the operation.- - - - - - - - - - ranking = 2keywords = haemorrhage (Clic here for more details about this article) |
7/38. Central haemangioma: variance in radiographic appearance.Central haemangioma, a "great mimicker" which, fortunately, is a relatively rare condition, may pose a lethal risk for the patient. The diagnosis may become apparent only during biopsy or tooth extraction, which poses a risk of lethal exsanguination; therefore a correct diagnosis is desirable before any biopsy is undertaken. The clinician may not anticipate the severe haemorrhage because of vague clinical history, physical findings and ambiguous radiographic characteristics of the lesion. We report a case of central haemangioma of the mandible whose clinical and radiographic features were equivocal. In addition, an attempt is made to discuss all possible radiographic presentations of central haemangioma and consider differential diagnosis. This case is significant for the reason that it had diverse radiographic appearances in various areas of the lesion in different projections.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
8/38. Blue rubber bleb naevus syndrome associated with cortical blindness.An 83-year-old woman was admitted for investigation of sudden loss of vision. Extensive plum-purple papules and nodules involved her skin and lips but not mucosae. A cutaneous biopsy demonstrated irregular vascular cavernous channels in the dermis and subcutis; deeper vessels displayed smooth muscle. Blue rubber bleb naevus syndrome was diagnosed. This patient had no gastrointestinal symptoms, no family history of blue rubber bleb naevus syndrome, and only developed cutaneous signs after 60 years of age. magnetic resonance imaging of the brain found multiple cerebral and cerebellar cavernomas with two larger foci of haemorrhage in both occipital lobes, with the largest in the right occipital lobe being associated with calcification. These most likely represent bleeding in relation to cavernomas believed to be the cause of decreased vision, predominantly in the left eye.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
9/38. vascular malformations of the tongue: MRI findings on three cases.vascular malformations are common lesions accounting for approximately 7% of all benign tumours, the majority of which develop in the head and neck region. Generally, vascular malformations such as lymphangiomas, haemangiomas, and arteriovenous communications in the head and the neck represent only an aesthetic problem. However, when localized in the tongue, these lesions can create clinical problems consisting, in the majority of cases, in spontaneous haemorrhage from the mouth. Although uncommon, progressive asymmetric growth of the tongue (macroglossia) can be also observed. Three consecutive cases of vascular malformations of the tongue have been studied with magnetic resonance imaging (MRI). Neither contrast medium administration nor angio-MR technique was used. In our experience, MR appears to be the ideal technique to define the site, extension and origin of vascular malformations, due to its ability to depict the typical signal flow voids in the lesions and to differentiate slow-flow lesions from high-flow ones.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
