Synovial and tenosynovial lipoma arborescens of the ankle in an adult: a case report

Case Report


Lipoma arborescens is a rare benign fat-containing synovial proliferative lesion that is typically known to affect the knee joint in adults. We present the first case of lipoma arborescens of the ankle joint in an adult patient with involvement of the intra-articluar synovium as well as the synovial sheath of the tendons around the ankle. The MRI features of this lesion in the adult ankle are described.
