title: Crohn's disease presenting as left gluteal abscess.
abstract: Although abscesses and fistulae are common complications of Crohn's disease, the gluteal area is a rare site for abscess formation. The abscess results from extension of pus through the fascial plains of the pelvis and through the greater sciatic foramen into the gluteal area. This is the first reported left gluteal abscess due to Crohn's disease as pus extends across the midline to the left side. The clinical picture can be misleading and diagnosing the source of infection may be difficult. Incision of this abscess without identifying the source of infection will result in enterocutaneous fistula. Ultrasound guided aspiration of the abscess as well as treatment of metabolic deficiencies and septicaemia before definitive surgical treatment of the bowel disease will reduce the morbidity and mortality of this rare complication. The clinical picture, management of this complication and review of the literature are discussed.
