Large Intra-articular Synovial Lipoma of the Knee: A Case Report and Review of Literature

Intra-articular synovial lipomas are a rare entity and have been reported in the knee, hip, spine, elbow, and wrist. Here we present the case of a 63-year-old female with a large intra-articular synovial lipoma of the knee joint causing restriction of range of motion. MRI showed an intra-articular lipoma arising from Hoffa’s fat pad. The mass was surgically excised with no recurrence. Magnetic resonance imaging (MRI) remains the diagnostic modality of choice.
