title: Lumbar vertebral hemangioma presenting with the acute onset of neurological symptoms. Case report.
abstract: Vertebral hemangiomas are common entities that rarely present with neurological deficits. The authors report the unusual case of a large L-3 vertebral hemangioma with epidural extension in a 27-year-old woman who presented with hip flexor and quadriceps weakness, foot drop, and leg pain. The characteristics of the mass on magnetic resonance imaging suggested an aggressive, hypervascular lesion. The patient underwent embolization of the lesion followed by direct intralesional injection of ethanol. Significant resolution of clinical symptoms was observed immediately after the procedure and at her follow-up visits. Follow-up imaging studies obtained 9 months after the procedure also documented a considerable reduction in the size of the hemangioma with minimal loss of vertebral height and a mild kyphosis at the affected level. On repeated imaging studies obtained 21 months postoperatively, the size of the hemangioma and the degree of vertebral body compression were stable. As demonstrated in this case, patients with vertebral hemangiomas can present with acute nerve root compression and signs and symptoms similar to those of disc herniation. Vertebral hemangiomas can be treated effectively with interventional techniques such as embolization and ethanol injection.
