Osteitis pubis

Description: Radiology Picture of the Day
Osteitis pubis is characterised by non-infectious inflammation of the pubic symphysis. The commonest causes are pregnancy/childbirth, high-level athletic activity, urological or gynaecological surgery, trauma and psoriatic arthritis, though the aetiology is sometimes unknown. The x-ray findings are subchondral erosive change, joint irregularity and sclerosis, which may eventually lead to ankylosis. The main differential diagnoses are infection and hyperparathyroidism, the latter due to bone resorption.
