SPINAL-CORD SARCOIDOSIS - MRI FINDINGS IN RESPONSE TO TREATMENT

The unusual case of a 64-year-old female with sarcoidosis involving the spinal cord is reported. Diffuse swelling of the cord with nodular lesions was observed on MRI. The lesions showed a low intensity area on the T1-weighted image. Following the administration of gadolinium-diethylenetriamine pentaacetic acid, the spinal cord, especially the nodular lesions, was diffusely enhanced. Serum levels of anti-endothelial cell antibodies and antinuclear antibodies were elevated. The diagnosis was confirmed by transbronchial lung biopsy which revealed noncaseating granulomas with giant epithelioid cells. The administration of prednisolone, 40 mg/day for 4 weeks, induced a remission.
