On physical examination, the patient was found to have several large, asymptomatic, soft issue masses in both thighs that resulted in this coronal T1-weighted MRI study. It shows the classic low signal features of fibrous dysplasia in the femur on the right side, surrounded by large, low signal, soft tissue masses both lateral and medial to the shaft of the femur. There is a large low signal mass seen in the adductor compartment on the opposite (left) side. On biopsy, the masses turned out to be benign, soft tissue mxyomas, characteristic of the so-called Mazabraud syndrome that is seen in a very small variant group of patients with polyostotic fibrous dysplasia.
