title: Multiple osteochondritis dissecans of knee joint in a patient with Wilson disease, focusing on magnetic resonance findings.
abstract: A 17-year-old man was admitted with a complaint of knee pain. He was diagnosed with Wilson disease by ophthalmologic and laboratory studies during hospitalization. Initial plain radiography of both knees showed multiple osteochondritis dissecans (OCD) on the medial and lateral femoral condyles of both knees. Subsequent magnetic resonance imaging showed multiple OCDs, which were symmetric on both knees. Subchondral cysts on the medial condyle and trochlear dysplasia were additionally evident on both femurs. We report this case with a focus on the imaging findings.
