    Cavernous angioma of the cauda equina: case report
    (Academia Brasileira de Neurologia - ABNEURO, 2004-06-01) Falavigna, Asdrubal; Righesso Neto, Orlando; Santos, José Augusto Nasser dos [UNIFESP]; Ferraz, Fernando Antonio Patriani [UNIFESP]; Caxias do Sul University Department of Neurosurgery; Caxias do Sul University Department of Orthopaedic Surgery; Universidade Federal de São Paulo (UNIFESP)
    We present a rare case of cavernous angioma of the cauda equina and review the eleven cases available in the literature. A 44-year-old woman presented with low back pain and sciatica associated with bowel and bladder dysfunction and motor weakness of the lower extremity. The MRI revealed an enhancing, heterogeneous and hyperintense intradural lesion compressing the cauda equina roots at the L4 level. Laminectomy at L3-L4 and total removal of the tumor were performed without additional neurological deficit. Pathology revealed a cavernous angioma. The literature, clinical presentation, technical examinations, and treatment are reviewed.

    Surgery of arteriovenous malformations (AVM) and of cavernous angiomas (cavernoma) in the majority of cases is indicated subsequently to episodes of bleeding. With the development of techniques for diagnosis and surgery for epilepsy of difficult control, indication for surgery of these vascular lesions has become greater. We present nine patients with cerebral vascular lesions and very frequent crises in spite of adequate clinical treatment. Ages ranged from 12 to 42 years with an average of 25 years; there was a prevalence of the male sex (2:1). Surgery consisted of exeresis of the lesion in all cases and in four there was also resection of the perilesional irritative area shown by electrocorticography. The pathologic study of lesions showed five cases of cavernoma, three cases of AVM, and one case of venous angioma. As to localization, we observed three lesions in the temporal lobe, four in the frontal, and two in the parietal region. Outpatient follow-up showed a reduction in crises in all of the patients, and seven evolved seizure free following surgery.
