Maffucci's syndrome is associated with tumours of the soft tissues and enchondromas. The hands are involved in the majority of patients. Magnetic resonance imaging (MRI) enables the demonstration of the soft tissue structures and the bone marrow of the hand. The hands of 19-year old patient with Maffucci's syndrome were examined via MRI and the results were compared with radiographs, angiograms and skeletal scintiscans of the hands. MR imaging shows a more expansive infestation with enchondromas than the radiographs. Haemangiomas were also visualised.
