title: Left sided diverticulitis presenting as a right lumbar fistula: a case report.
abstract: The formation of fistulae is a recognised complication of diverticulitis. This case report describes sigmoid diverticulitis presenting as a right psoas abscess with a colocutaneous fistula. The report highlights the role of appropriate imaging and a high index of suspicion in anyone presenting with a discharging lumbar abscess, especially when the focus of infection may be from a contra-lateral source.
