Clinical History
60 year old female with right hip pain and fullness.
Diagnosis: Iliopsoas Bursitis
The iliopsoas bursa is located deep to the iliopsoas tendon as the tendon crosses the anterior rim of the acetabulum, functioning to reduce friction between the tendon and the acetabulum.
Fluid in the iliopsoas bursa is usually due either to irritation of the iliopsoas tendon or fluid spontaneously decompressing from the hip joint.
Fluid in the iliopsoas bursa can present with pain and/or mass-like lesion in the groin.
Ultrasound is an excellent modality for confirming the diagnosis of iliopsoas bursitis, and for guiding aspiration +/- cortisone injection.
If there is any concern for the bursal fluid being infected, then the aspirated fluid should be sent for cell count and culture analysis.
