1/31. Radiological and histological findings in spinal intramedullary angiolipoma.We report an intramedullary angiolipoma with spinal cord compression studied by MRI, angiography and CT. Angiolipomas of the spine are rare benign tumours containing vascular and mature adipose elements. They are epidural in more than 90 % of the cases; only three cases of intramedullary angiolipoma are described. The clinical picture is nonspecific, but MRI and CT suggest the diagnosis.- - - - - - - - - - ranking = 1keywords = spinal (Clic here for more details about this article) |
2/31. Spinal angiolipoma: case report and review of literature.Spinal extradural angiolipomas are distinct, benign, and rare lesions composed of mature lipocytes admixed with abnormal blood vessels. They account for 0.14% of all spinal axis tumors. The case described here was a 72-year-old patient presenting with a history of paraparesis, hypoesthesia under the T2 level, hyperreflexia, and urinary overflow incontinence that appeared within 7 days after the administration of a coronary vasodilator drug regimen. The spinal magnetic resonance scan showed a lipomatous mass with signal void lesions, suggesting a vascular component of the tumor. The patient improved rapidly after surgical resection of the epidural tumor and decompression of the cord. According to the present literature, the duration of neurological symptoms ranges from 1 to 180 months (mean 28 months). But this patient's neurological deterioration took place 4 days before hospitalization. We believe that this can be explained by the increased tumor blood volume caused by vasodilator drugs, which in turn exerted a pulsatile compressive effect on the cord.- - - - - - - - - - ranking = 0.4keywords = spinal (Clic here for more details about this article) |
3/31. Revisited: spinal angiolipoma--three additional cases.Angiolipomas are benign tumours which usually arise from subcutaneous tissue, particularly in the forearm, but they do occur rarely in the spinal canal. To the best of our knowledge 60 cases of histologically confirmed spinal angiolipoma have been reported in the medical literature. They show a female predominance (1.6:1), and the mean age at presentation is 43 years. They usually arise in the thoracic spine, most cases presenting with slowly progressive signs and symptoms of cord compression. Rarely, massive acute haemorrhage into the tumour may herald its presence. Surgical resection or decompression are the most satisfactory methods of treatment in most patients. We describe three further cases of spinal angiolipoma, and discuss their aetiology, pathogenesis, clinico-pathological features and surgical management.- - - - - - - - - - ranking = 1.954848823076keywords = spinal canal, spinal, canal (Clic here for more details about this article) |
4/31. Spinal angiolipomas: report of a case and review of the cases published since the discovery of the tumour in 1890.Angiolipomas of the spinal canal are extremely uncommon benign neoplasms composed of mature lipomatous and angiomatous elements. A case of thoracic spinal extradural angiolipoma producing progressive spinal cord compression in a 54-year old housewife is presented and 74 previously reported cases in the world literature over a period spanning nearly one century from 1890 to the present are analysed. The 75 total cases (46 females and 29 males) ranged in age from 6 to 73 years (mean 42.7, SD 15.9; median 43). The angiolipomas were located in the extradural compartment in 72 patients and intradural compartment in 3; 14 of the extradural lesions infiltrated the surrounding bone (infiltrating subgroup). Computed tomography (CT) and magnetic resonance imaging (MRI) revealed the fat-density lesions in all the cases that we studied. The findings indicate that spinal angiolipomas predominantly affect women. Their preponderance in peri- or postmenopausal women, and their fluctuating clinical course during the pregnancy support a role of hormonal influence on the development of the lesion. They often involve the thoracic region, and produce symptoms and signs of spinal compression and, in some cases, bone involvement. MRI is the investigation of choice for the diagnosis of these lesions. Non-infiltrating angiolipomas can usually be removed easily through a laminectomy, but infiltrating angiolipoma can be only partially resected. However, outcome is not worse in the infiltrating than in the non-infiltrating lesions and appears to be relatively independent of the completeness of the surgical removal. Subtotal resection usually provides substantial symptomatic relief, because these lesions are slow growing and do not undergo malignant transformation. The results of this review show that angiolipomas of the spinal canal have a good prognosis after surgical removal, even if infiltrating.- - - - - - - - - - ranking = 2.309697646152keywords = spinal canal, spinal, canal (Clic here for more details about this article) |
5/31. Dorsal thoracic cord compression from a spinal angiolipoma: case report and brief comment.Angiolipomas are benign tumors usually found in the forearms of young adults. To the best of our knowledge only 63 cases of spinal angiolipomas have been reported in the literature up until 1999 (medline 1966-1999). We report a case of a spinal angiolipoma causing dorsal cord compression in a 44-year-old woman presenting with subacute lower limb paresthesias, in the absence of sensory or motor findings, which mimicked multiple sclerosis by history. Operative intervention was curative.- - - - - - - - - - ranking = 1.2keywords = spinal (Clic here for more details about this article) |

7/31. Angiolipomas of the central nervous system.Angiolipomas are neoplasms composed of mature adipocytes admixed with abnormal vascular elements. They are most commonly found in the subcutaneous tissue of the trunk and extremities, but other sites have been reported. The craniospinal axis is an uncommon but significant site. An extensive review of the literature is conducted. We summarize 94 cases of angiolipomas in the central nervous system (CNS) in 92 patients, including five in our own series, to highlight the most prominent features of these tumors. The increasing number of cases of CNS angiolipoma in the era of magnetic resonance imaging raises the question of the rarity of these lesions.- - - - - - - - - - ranking = 0.2keywords = spinal (Clic here for more details about this article) |
8/31. Spinal angiolipoma.BACKGROUND: Spinal epidural angiolipoma is a rare cause of spinal cord compression. We present a case and review the clinical presentation, radiological appearance, pathological aspects and treatment of this distinct clinico-pathological entity. methods: A case of a 46-year-old woman with a five-month history of progressive myelopathy affecting her lower extremities is presented. CT and MRI revealed a large epidural fat-containing mass compressing the spinal cord dorsally at the T7-T8 level. A laminectomy was performed with gross total resection of the lesion. RESULTS: The patient's neurologic symptoms improved postoperatively. A two-year follow-up period has revealed no signs of tumor recurrence and no neurological deficit. CONCLUSION: The diagnosis of spinal angiolipoma should be considered in the differential diagnosis of spinal cord compression. magnetic resonance imaging is the investigation of choice. The surgical objective is complete excision but, for anterior lesions involving bone, an overly aggressive approach should be tempered by an awareness of the overall indolent natural history of so-called "infiltrating" spinal angiolipomas that are only partially excised.- - - - - - - - - - ranking = 1keywords = spinal (Clic here for more details about this article) |
9/31. Thoracoscopic techniques in the management of benign mediastinal dumbbell tumors.Mediastinal dumbbell tumors can be resected with a variety of open surgical approaches. Recently, thoracoscopic techniques have been suggested for the treatment of benign neurogenic lesions. Over a 5-year period, three patients with a benign mediastinal dumbbell tumor were treated via a combined microneurosurgical and thoracoscopic approach. The neurosurgical phase consisted of a posterior laminectomy to free the tumor from the spinal cord, followed by an intervertebral foraminotomy. Thoracoscopic resection of the lesion was then performed in the same setting. The operative times were 240, 260, and 280 min, and there were no operative complications. The postoperative stays were 6, 7, and 7 days; the postoperative period was uneventful in all three patients. Pathologic examination revealed a benign schwannoma in two cases and an angiolipoma in one case. One patient reported the onset of paraesthesia in the left hypocondrium on the distribution area of the transected T10 and T11 intercostal nerves; slight paraesthesia still remains 15 months from surgery. We conclude that the combined posterior neurosurgical and thoracoscopic approach is a safe and effective method for the removal of benign mediastinal dumbbell tumors, whether neurogenic or nonneurogenic in origin.- - - - - - - - - - ranking = 0.2keywords = spinal (Clic here for more details about this article) |
