Abstract

Lipohemarthrosis is well known to be associated with intra-articular fractures throughout the body. Despite the relatively common occurrence of hip fracture and the frequency of communication between the hip joint and iliopsoas bursa, to the best of our knowledge, a fat-fluid level involving the iliopsoas bursa secondary to a hip fracture has not previously been reported. The following is a case report of a 48-year-old male who sustained an acute femoral neck fracture and was found to have distension of the iliopsoas bursa with a fat-fluid level resulting from extra-capsular extension of a lipohemarthrosis. The imaging findings, relevant anatomy, and potential importance of this finding for the detection of hip fracture are discussed.
