Cavernoma of the cauda equina mimicking schwannoma: A case report.

Cavernous malformations (CMs), also known as cavernomas or cavernous hemangiomas, are vascular lesions characterized by clusters of abnormally dilated blood vessels resembling a mulberry. In this report, we present the case of a 40-year-old man who presented with a one-year history of back pain radiating into both legs, with a preference for the left leg. An MRI initially suggested a schwannoma at the T12-L1 vertebral level, with a differential diagnosis that included meningioma-2 common intradural-extramedullary spinal tumors- with distinct management and prognostic implications.
