Abstract
Synovial sarcoma of bone origin is extremely rare and difficult to diagnose. We present a case in which the lesion arose in the cortex of the distal tibia. It showed heterogeneous intermediate signal intensity on T1-weighted images and heterogeneous intermediate to low signal intensity on T2-weighted images with heterogeneous contrast enhancement on MRI. The lesion was confirmed as synovial sarcoma using a combination of histological and molecular genetic studies.
