Distended left iliopsoas bursa - causing acute femoral nerve palsy

Case contributed by Dr Chris O'Donnell


Acute left hip pain and weakness of left hip flexors

Patient Data

Age: 73
Gender: Male

Large fluid filled mass arising from the joint anteriorly is typical of a distended iliopsoas bursa. These can present as a mass in the groin. In this case it appears to have increased in size rapidly (possibly due to hip joint synovitis as it is in continuity with the joint) compressing and distorting the neurovascular bundle specifically the femoral nerve producing a clinical femoral nerve palsy i.e. weak hip flexors

Ultrasound performed to confirm cystic nature of mass and to allow guided aspiration of the cyst and injcetion of steroid into the cyst
