MRI of intramedullary sarcoidosis: follow-up of a case.

Intramedullary lesions are infrequently the first manifestation of sarcoidosis. We present clinical and radiological follow-up of spinal cord sarcoidosis in a 68-year-old woman, mimicking an intramedullary tumour. MRI revealed an unusual area of low signal intensity on T2-weighted spin-echo images at the core of the lesion, consistent with calcification. Clinical and MRI follow-up showed progressive resolution of the intraspinal lesion, except for the calcification, with oral steroid therapy.
