Rectus sheath haematoma.

Rectus sheath haematoma is an unusual, though well recognised condition. It is the most common non-neoplastic condition of the rectus abdominis muscle and sheath.' It may mimic acute intraabdominal pathology and should therefore be considered in the differential diagnosis of the acute abdomen. The diagnosis is easily confirmed using computerised tomography or ultrasound scanning. In this report we present a case of rectus sheath haematoma and a review of the literature.
