Angiolipoma is a histological variant of the more common lipoma that may occur superficially throughout the body. After review of recent literature, different cases of angiolipomas were reported within various areas, more so in the upper extremity and truncal regions [1,2]. Our clinical case demonstrates an extremely rare presentation of a non-infiltrating angiolipoma lesion growing within a hamstrings autograft after anterior cruciate ligament (ACL) reconstruction. There have been a few prior reports of lower extremity intraarticular angiolipomas inside the knee, but to the best of our knowledge, none have been identified specifically within an ACL hamstrings autograft. This clinical case is of particular interest to orthopaedic surgeons and sports medicine specialists as a potential differential diagnosis for knee joint pain and disability without an obvious source.
