Synovial Lipomatosis is a rare entity of the synovial membrane, most often affects the knee joint, and can occur in other joints. It occurs in 5th or 6th decade of life, men of usual monoarticular presentation. Its etiology is unknown and there is more a reactive process rather than neoplastic. This disease has a characteristically arborescent radiological, macroscopic and microscopic morphology, due to adipose infiltration of the subsinovial tissue, which is key for its diagnosis. We present the case of a 63-year-old male, reviewing the radiological and pathological findings, as well as its differential diagnosis with other entities and their treatment.
