Spinal extradural cavernous angiomas(CAs) are apparently rare lesions. The author report a 67 year old man with an epidural CA at T9-10 space presenting with progressive leg weakness. Magnetic resonance imaging showed a thoracic epidural lesion appearing as isointense on T1-weighted with strong contrast enhancement and hyperintense on T2-weighted images. A moderate hyperdensity and foraminal widening was found on computed tomography. Hemilaminectomy was performed to relieve the spinal cord compression. A highly vascular tumor without bony involvement was observed in the epidural space. Histopathology of the lesion revealed a typical CA. The patient's symptoms resolved after treatment. Clinical aspect, radiological features, and surgical treatment of this rare entity will be reviewed.
