Bladder perforation: an unusual complication caused by rectus sheath haematoma.

Rectus sheath haematoma (RSH) is an uncommon cause of abdominal pain. Despite being previously viewed as a benign, self-limiting condition, there is increasing evidence suggesting significant local and systemic complications with RSH. We present a case of an 82-year-old female who developed a large RSH following prescription of therapeutic anticoagulation for her new onset atrial fibrillation.
