It is uncommon, mainly affecting men (there is a 3:1 male:female distribution) under 30 years of age on the right side. A secondary abscess usually arises from an extension of infection in adjacent pelvic and abdominal areas with Crohn’s disease being the most common associated condition. Plain film is usually non-diagnostic. Magnetic resonance imaging is the most useful diagnostic tool for suspected iliacus-psoas abscess in pregnancy because of its better soft tissue visualisation and no radiation involved as compared to CT. Depending on the stage of pregnancy and location of the abscess, either ultrasound or CT can be employed to aid the abscess drainage. Open surgical intervention may be required for certain deep iliacus-psoas abscess. While there are a number of reports of successful treatment following a prolonged course of antibiotics without drainage, some form of abscess evacuation is usually necessary to achieve a timely recovery. In our case, we undertook two aspirations with drainage catheter inserted and the patient still required one month’s hospitalisation.
