YR 2005 UL http://nsj.org.sa/content/10/1/101.abstract AB We present a case of intradural multiple ring-enhancing lesions in a 20-year-old male with symptoms and signs of progressive spastic paraparesis. An MRI of the thoracolumbar area showed 2 peculiar ring-enhancing lesions, at the level of T12 and L1. The differential diagnosis includes inflammatory or infectious lesions in addition to rare cystic tumors. The patient underwent surgical resection of the 2 lesions with an uneventful perioperative course. Histologically, the diagnosis was consistent with cystic schwannomas.
