Intra-articular lipoma of the hip. A case report.

This report describes a rare intra-articular lipoma of the hip which developed in a 31-year-old male after a football injury. A plain X-ray and an MRI scan of the hip showed no bony abnormalities. After the patient failed to improve with a rehabilitation programme, arthroscopy of the hip was performed, revealing a lump in the acetabular fossa associated with a labral tear. A histopathological analysis confirmed the diagnosis of an intra-articular lipoma of the hip joint, which to our knowledge is the first reported case in the literature.
