Abstract
We report a case of synovial chondroma of the left ankle in an 11-year-old boy presenting
with soft tissue swelling after recent trauma. The noncalcified or nonossified intraarticular
chondroma arising from metaplastic synovium has characteristic imaging appearance
on computed tomography (CT) and magnetic resonance imaging (MRI). A lobulated mass
of fluid-like density and signal intensity along with internal septa are characteristic
features on CT and MRI. The knowledge of CT and MRI features of noncalcified or nonossified
synovial chondroma is important to distinguish from the simple or complicated effusion,
hemarthrosis, or other synovial process.
