MR Features of Multiple Enchondromas with Associated Chondrosarcoma in the Lower Extremities

Abstract

Multiple enchondromas are well described in the literature, however, the associated spectrum of MR imaging findings remains unclear. Secondary chondrosarcoma of the hand and feet associated with multiple enchondromas is extremely rare. Herein, we reported a case of multiple enchondromas of intramedullary, intracortical, and periosteal location with associated low-grade chondrosarcomas in the lower extremities on MR imaging in a 57-year-old woman.
