1/17. 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 = 1keywords = vessel (Clic here for more details about this article) |
2/17. Cervical myelopathy due to compression by bilateral vertebral arteries--case report.A 69-year-old man presented with progressive cervical myelopathy due to vascular compression of the upper cervical spinal cord. Vertebral angiography and magnetic resonance imaging revealed that the elongated bilateral vertebral arteries (VAs) had compressed the spinal cord at the C-2 level. The spinal cord was surgically decompressed laterally by retracting the VAs with Gore-Tex tape and anchoring them to the dura. The patient's symptoms improved postoperatively. decompression and anchoring of the causative vessels is recommended due to the large size of the VAs.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/17. Spinal reconstruction for symptomatic thoracic haemangioma using a titanium cage.Most vertebral haemangiomas are asymptomatic. A case of spinal reconstruction for symptomatic extraosseous thoracic haemangioma using a titanium cage is reported. Radiographs of the T11 vertebra demonstrated characteristic vertical striations. magnetic resonance imaging and computed tomography showed spinal cord compression by extraosseous tumour extension. Several tumour feeding vessels were shown by angiography. Through a transpedicular biopsy, a histological diagnosis of cavernous haemangioma was made. Embolisation of feeding vessels was performed using coils before surgery. laminectomy and subtotal vertebrectomy were performed by a single posterior approach. Rigid stabilisation of the spine was achieved with pedicle screw systems and a cage filled with an autogenous bone graft. Five months postoperatively, stabilisation of the spine was established without loosening of the cage or pedicle screws. Clinical symptoms were improved.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
4/17. A spinal haematoma occurring in the subarachnoid as well as in the subdural space in a patient treated with anticoagulants.A 75-year-old man on anticoagulant therapy suddenly experienced an excruciating back pain and subsequently developed a paraplegia. At operation a subarachnoid and a subdural haematoma were found, extending between the levels of the vertebrae T3 and L2. This extremely rare combination of haematomas may have been caused either by rupture of a small vessel in the arachnoid membrane or by rupture of the arachnoid membrane itself, secondary to a massive haemorrhage in the subarachnoid space.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/17. Myelopathy due to spinal epidural abscess without cord compression: a diagnostic pitfall.Spinal epidural abscess (SEA) is a neurological emergency that requires urgent diagnosis and treatment. We report 2 patients with SEA, in whom, on neuropathological examination, the neurological signs were found to be caused by spinal cord ischemia due to thrombosis of leptomeningeal vessels and compression of spinal arteries, respectively, while evidence of spinal cord compression was absent. Clinicians and neuropathologists should be aware of the variable mechanisms underlying the neurological involvement in SEA. Absence of spinal cord compression by the abscess may hamper early diagnosis and treatment.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/17. Thoracic intradural extramedullary capillary hemangioma.We report a case of a thoracic intradural extramedullary capillary hemangioma. The MR imaging appearance was nonspecific for this lesion, and it could not be distinguished from more common spinal intradural extramedullary lesions. The presence of subtly enlarged abnormal vessels on contrast MR images should, however, lead one to consider a vascular mass and order preoperative spinal arteriography.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/17. Acute spinal cord compression caused by vertebral hemangioma.BACKGROUND CONTEXT: The reported incidence of vertebral hemangioma within the spinal column is common. Most often these benign vascular tumors are incidental radiographic findings and do not cause neurological sequelae. Rarely, vertebral hemangiomas will cause compressive neurological symptoms, such as radiculopathy, myelopathy and paralysis. In these cases the clinical presentation is usually the subacute or delayed onset of progressive neurological symptoms. This report demonstrates a symptomatic vertebral hemangioma presenting with rapid onset neurologic sequelae. PURPOSE: To discuss diagnostic and management issues presented by symptomatic vertebral hemangioma. STUDY DESIGN: Case report and review of literature. PATIENT SAMPLE: Sixty-one-year-old white woman with low back pain and rapidly progressive myelopathic symptoms. methods: A case of vertebral hemangioma with neurological sequelae is presented followed by a discussion of the literature concerning diagnostic and therapeutic options in the management of this pathologic entity. RESULTS: The results of our review reveal that the incidence of vertebral hemangioma causing compressive neurological symptoms is rare despite the overall prevalence of vertebral hemangioma. Vertebral hemangioma may present with rapid onset myelopathic symptoms and may mimic those symptoms caused by a malignancy. Radiographic imaging modalities are extremely useful and display characteristic findings in the diagnostic evaluation of these tumors. Angiographic embolization of feeding vessels has been effective in minimizing operative blood loss, and surgical decompression and stabilization is frequently indicated. Postsurgical radiotherapy has also been demonstrated to serve as a limited adjunct to surgery by reducing tumor recurrence in the event of less than complete tumor resection. CONCLUSIONS: Because of the rapid presentation of myelopathic symptoms in this case, preoperative angiographic embolization was not performed, and the patient underwent emergent decompressive surgery. In this case emergent operative decompression and stabilization was effective in reversing the patient's myelopathic symptoms, while maintaining long-term stability of the spinal column. Postoperative radiation was not administered because of the extent of tumor resection. Surgical intervention has produced long-term cure of this patient's myelopathy and T10 vertebral hemangioma.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/17. Lumbar hemorrhagic synovial cysts: diagnosis, pathogenesis, and treatment. Report of 3 cases.BACKGROUND: To define the etiologic, clinical, histological, and surgical features of lumbar hemorrhagic synovial cysts (LHSCs). Three personal cases are reported together with a review of the pertinent literature. methods: We identified 3 cases of LHSC treated in our departments and 20 cases culled from the literature. RESULTS: A total of 23 cases of LHSC were selected. All the patients underwent surgical treatment because of untreatable radicular pain and/or neurological deficits. The amount of bleeding, either massive or minor but repeated, influenced the timing of surgery. In our cases, the histological examinations showed an inflammatory reaction within the cyst and the consequent formation of neoangiogenic vessels. CONCLUSIONS: Hemorrhagic synovial cyst of the spine is rare and its most common localization is lumbar. Bleeding within the cyst leads to an increase of its volume, accompanied by neurological deficits and/or painful symptoms that are violent and generally intractable. In this event, surgical excision is the treatment of choice and, in some cases, emergency surgery is necessary. Hemorrhages are probably caused by the rupture of fragile neoangiogenic vessels.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
9/17. Thoracic spine extradural arteriovenous fistula: case report and review of the literature.BACKGROUND: Spinal extradural arteriovenous fistula is a rare, disabling, but potentially treatable disease. Only 27 cases have been reported so far in the past 40 years. CASE DESCRIPTION: An 18-year-old adolescent girl developed repeated back pain and mild paraplegia after a training course. magnetic resonance imaging revealed a vessel-like lesion at the spinal extradural space, compressing the spinal medulla at the T5 level. angiography disclosed a focal fistula fed by branches of the intercostal artery. The vascular mass was surgically removed and confirmed pathologically. CONCLUSION: Spinal extradural arteriovenous fistulas have an arterial supply that originates outside the spinal dura, with venous draining into the spinal extradural venous plexus. They may lead to myelopathy, radiculopathy, or spontaneous extradural hematoma, due to dilated vein compression, blood stealing, or spinal venous hypertension. Extradural hematoma needs emergency laminectomy and clot evacuation. And extradural arteriovenous fistulas should be treated actively by embolization, surgical resection, or both. Appropriate treatment will stabilize the patient or result in neurological improvement.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/17. Cervical myelopathy due to atlantoaxial and subaxial subluxation in rheumatoid arthritis.Four patients aged 41 to 73 years, who had had rheumatoid arthritis for eight to 25 years, had signs and symptoms of cervical myelopathy and radiculopathy due to either atlantoaxial dislocation with herniation of the odontoid through the foramen magnum, or subluxation of the middle to lower cervical vertebrae. Spastic paraparesis or quadriparesis, severe nuchal immobility and pain, and flaccid paresis of the upper limbs necessitated anterior medullary decompression and posterior cervical fusion. Postmortem examination disclosed old ischemic necrosis, atrophy, and gliosis in the low medulla and cervical cord. Anterior and posterior gray horns and contiguous posterior and lateral funiculi bore the brunt of the damage. Ascending and descending wallerian degeneration and atrophy of the cervical nerve root were evident. In three cases, anterior spinal or radicular arteries demonstrated intimal fibrosis with moderate stenosis; two cases depicted chronic phlebitis or subarachnoid vessels. Previous reports have infrequently provided evidence of a vasculopathy.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
