Dr. Chaabra’s nice cases inspired me to share an unusual case of synovial chondromatosis I had recently.
Pancarpal synovial chondromatosis involving radiocarpal, DRUJ, midcarpal, and CMC joints. Various degrees of ossification, from purely cartilaginous to mature. Mass effect on carpal tunnel, patient presented with carpal tunnel syndrome and wrist deformity. Areas of extrinsic erosion. Subsequent surgical decompression with improvement in carpal tunnel symptoms. Path confirmed. Has anyone seen pancarpal synovial chondromatosis before? The polyarticular involvement I feel is unique and difficult for me to wrap my head around.
