AIRP Best Cases in Radiologic-Pathologic Correlation: Synovial Chondrosarcoma
A 38-year-old woman presented to the orthopedics clinic at our institution after several months of increased right hip pain and diffculty in ambulation. At physical examination, she had a dysfunctional gait with excessive fexion and limited range of motion in the right hip because of pain. She had a palpable mass in the right inguinal region that extended distally along the lateral aspect of the proximal femur and the medial aspect of the upper thigh. The masslike formation was nonmobile and somewhat tender when palpated. Three and a half years earlier, the patient had undergone surgical dislocation with full synovectomy and greater trochanteric osteotomy for treatment of synovial chondromatosis. She recovered well postoperatively and experienced no further manifestations of disease until several months before this presentation.
