Infiltrating spinal angiolipoma: a case report and review of the literature.

Angiolipomas are rarely encountered in the spine. We report the case of a 47-year-old man with a thoracic angiolipoma involving the T9 vertebral body. A preoperative spinal angiogram confirmed a highly vascular neoplasm. The lesion was treated with endovascular embolization prior to a T9 corpectomy and resection of the epidural component of the tumor. At time of surgery, minimal blood loss occurred during resection of the vertebral body and the epidural mass. Pathologic examination demonstrated features consistent with spinal angiolipoma. This report emphasizes the clinical, radiographic, and pathologic features of infiltrating spinal angiolipoma and discusses therapeutic management options.
