1/127. Cavernous angioma of the conus medullaris as a cause of paraplegia.Cavernous angiomas of the conus medullaris are unusual lesions, representing about 3% of all intramedullary cavernomas. Most are asymptomatic. magnetic resonance imaging (MRI) is the best diagnostic tool for the detection. We report a case of a 74-year-old man who initially developed low back pain and numbness of the right leg and subsequently paraplegia, asia impairment scale 'c'. MRI revealed a cavernous angioma of the conus medullaris with perilesional oedema and signs of acute bleeding. Clinical improvement was associated with changes in the MRI.- - - - - - - - - - ranking = 1keywords = angioma (Clic here for more details about this article) |
2/127. Conus medullaris hematomyelia associated with an intradural-extramedullary cavernous angioma.A unique case of a 50-year-old woman with a conus medullaris hematomyelia associated with a low thoracic intradural-extramedullary cavernous angioma localized 2 cm above is reported. The patient had a 2-month history of progressive paraparesis, hypoesthesia of legs, and bowel and bladder disturbances. The symptoms worsened acutely during the last days before admission. A thoraco-lumbar MRI showed a space-occupying lesion at T10-T11 (vertebral interspace associated with a hematomyelia localized about 2 cm below. A T10-L1 laminectomy was performed and complete removal of both lesions was obtained with microsurgical technique. A non-traumatic hematomyelia should always prompt the suspicion of a spinal AVM or, more rarely, of a cavernous angioma. The possible anatomical and clinical correlations of this unusual association are discussed.- - - - - - - - - - ranking = 1keywords = angioma (Clic here for more details about this article) |
3/127. Posterior mediastinal capillary hemangioma with extradural extension resembling neuroblastoma.We present two patients with posterior mediastinal capillary hemangiomas that were paraspinal and had intraspinal extension. Computed tomography demonstrated the strikingly hypervascular nature of these tumors, distinguishing them from neuroblastoma.- - - - - - - - - - ranking = 123.79100298376keywords = hemangioma, angioma (Clic here for more details about this article) |
4/127. Acute spinal cord compression due to intraspinal bleeding from a vertebral hemangioma: two case-reports.Vertebral hemangiomas can cause acute spinal cord compression either after a minor trauma or during the last 3 months of pregnancy. Failure to recognize the lesion can lead to potentially serious treatment delays. An emergency MRI scan usually establishes the diagnosis of vertebral hemangioma responsible for spinal cord compression requiring laminectomy. We report two cases showing that posterior fixation should be considered: in our experience it prevents vertebral collapse during the interval preceding secondary vertebroplasty, which, if performed, provides highly significant pain relief.- - - - - - - - - - ranking = 148.54920358051keywords = hemangioma, angioma (Clic here for more details about this article) |
5/127. Radiologic and surgical aspects of pure spinal epidural cavernous angiomas. Report on 5 cases and review of the literature.BACKGROUND: Cavernous angiomas (CAs) that are localized completely in the spinal epidural space are uncommon vascular malformations. Although they have increasingly been reported in the literature in recent years, diagnostic and surgical features are not clearly defined. methods: We report five patients with pure spinal epidural cavernous angiomas (PSECAs) and review the literature, focusing on their radiologic and surgical characteristics. We also compare these tumors with other extra-axial CAs as well as with their intra-axial counterparts. RESULTS: PSECAs, like all other extra-axial CAs, differ from intra-axial ones on MRI: the hemorrhagic variant is less frequent, hemosiderin rim is rare, the signal is different, and contrast enhancement is the rule. They are very similar to spinal meningiomas but they differ in their growth pattern and morphology, since they infiltrate intervertebral foramina and have an oval shape. In PSECA, intraoperative bleeding is rarely profuse, in contrast to other extra-axial CAs, especially those of the cavernous sinus. CONCLUSIONS: On MRI, PSECAs and other extra-axial CAs constitute a homogeneous group since they enhance significantly. At operation, since there is rarely enough bleeding to limit removal, radical excision of PSECAs can be achieved with good results.- - - - - - - - - - ranking = 1keywords = angioma (Clic here for more details about this article) |
6/127. brown-sequard syndrome after management of vertebral hemangioma with intralesional alcohol. A case report.STUDY DESIGN: This report describes brown-sequard syndrome after intralesional injection of absolute alcohol into vertebral hemangioma. OBJECTIVE: To discuss whether the described technique is safe in the management of vertebral hemangiomas. SUMMARY OF BACKGROUND DATA: The management of vertebral hemangiomas remains controversial. There have been reports of successful management using intralesional absolute alcohol. methods: The clinical and radiologic features of the reported complication are detailed. RESULTS: Intralesional injection of absolute alcohol caused brown-sequard syndrome. CONCLUSION: This case shows that intralesional alcohol injection cannot be considered a safe technique for management of vertebral hemangiomas with spinal cord compression.- - - - - - - - - - ranking = 198.06560477401keywords = hemangioma, angioma (Clic here for more details about this article) |
7/127. Vascular lesions of the lumbar epidural space: magnetic resonance imaging features of epidural cavernous hemangioma and epidural hematoma.The authors report the magnetic resonance imaging diagnostic features in two cases with respectively lumbar epidural hematoma and cavernous hemangioma of the lumbar epidural space. Enhanced MRI T1-weighted scans show a hyperintense signal rim surrounding the vascular lesion. Non-enhanced T2-weighted scnas showed hyperintense signal.- - - - - - - - - - ranking = 123.79100298376keywords = hemangioma, angioma (Clic here for more details about this article) |
8/127. 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 = 0.16666666666667keywords = angioma (Clic here for more details about this article) |
9/127. Extraosseous extension of vertebral hemangioma, a rare cause of spinal cord compression.STUDY DESIGN: Case report. OBJECTIVE: To illustrate a rare cause of thoracic spinal cord compression, its diagnosis, and its management. SUMMARY OF BACKGROUND DATA: Asymptomatic vertebral hemangiomas are common, but extraosseous extension causing spinal cord compression with neurologic symptoms is rare, and few cases appear in the English-language literature. METHOD: A previously asymptomatic 63-year-old man sought medical attention for acute back pain and thoracic myelopathy of 6 week's duration. magnetic resonance imaging confirmed the presence of a mass in the T10 vertebral body with paravertebral and intracanalicular extension contributing to cord compression. decompression and reconstructive surgery were performed and radiotherapy administered after surgery. Preoperative angiography was not performed because of the patient's rapidly progressive neurologic deterioration and the consideration that the differential diagnosis of vertebral hemangioma was less likely. RESULTS: The diagnosis of benign capillary hemangioma was made histologically. Neurologic recovery was complete except for minor residual sensory changes in the legs. At follow-up 10 months after surgery the patient had returned to his usual active life and motor mower repairing business. CONCLUSION: Extraosseous extension of vertebral hemangiomas is a rare cause of thoracic spinal cord compression. As such, the available data are derived from reports based on series involving only a small number of cases, rather than on results of randomized controlled trials. Those causing progressive neurologic symptoms should be surgically decompressed, with the specific procedure determined by the extent and site of the lesion. Preoperative angiography is recommended, but embolization is not always necessary or even possible. Postoperative radiotherapy is recommended when tumor removal is subtotal.- - - - - - - - - - ranking = 198.06560477401keywords = hemangioma, angioma (Clic here for more details about this article) |
10/127. Multiple spinal "miliary" hemangioblastomas in von Hippel-Lindau (vHL) disease without cerebellar involvement. A case report and review of the literature.We report on a 57-year-old male presenting with radicular pain in the nerve roots of L5 and S1 on the right side and dysuria. magnetic resonance imaging (MRI) of the lumbar spine showed multiple (up to 20) small, intradural enhancing nodules attached to the cauda equina down to the sacrum, the largest 1 cm in diameter at the level Th12/L1 compressing the conus. Additionally, small nodules in the cervico-thoracal region adjacent to the cord, but no cerebellar or cerebral abnormalities, were detected in a consecutive MRI of the remaining neuroaxis. The histology of a resected lesion at Th12/L1 revealed hemangioblastoma of the reticular type. Together with a history of left eye enucleation performed 17 years ago for angiomatosis of the retina and the immunohistochemical detection of von Hippel-Lindau (vHL) protein within the removed spinal hemangioblastoma, a diagnosis of vHL disease was established. family history and screening for visceral manifestations of vHL disease were negative. In contrast to cerebellar or solitary spinal hemangioblastomas, multiple spinal hemangioblastomas without cerebellar involvement in vHL represent unusual manifestations. Unlike the case for solitary lesions in non-syndromic patients, a surgical cure does not seem feasible in this case. The role of treatment modalities is discussed.- - - - - - - - - - ranking = 0.16666666666667keywords = angioma (Clic here for more details about this article) |
