Painful Enchondroma of the Tibial Tuberosity: A Case Report

Enchondromas are defined as benign tumors of cartilaginous origin, often discovered incidentally. We report a case of a tibial enchondroma in a 40-year-old woman who presented with inflammatory-type leg pain. Standard imaging revealed a well-defined, multilobulated intramedullary osteolytic lesion centered on the tibial tuberosity, with no periosteal reaction or soft tissue involvement. CT scan confirmed the diagnosis of enchondroma. We will discuss the main clinical, radiological, and histological features, as well as therapeutic options. This case is notable for its unusual location at the tibial tuberosity, its painful presentation, and the absence of signs of complication.
