Sciatica as the first manifestation of synovial sarcoma. Contribution of magnetic resonance imaging to the diagnosis.

ABSTRACT

A 38-year-old man presented with paralyzing sciatica as the first manifestation of synovial sarcoma of his right leg. Although neurologic symptoms sometimes occur as manifestations of synovial sarcoma, they are exceptionally inaugural. Magnetic resonance imaging is a valuable tool in patients with synovial tumors, both for establishing the diagnosis and for evaluating the extent of the lesion.
