An unusual presentation of Meckel's diverticulum.

Meckel's diverticulum can present with unusual symptoms and signs and therefore delay diagnosis. We present the case of a 63 year old lady who presented to the gynaecologists with a huge right sided ovarian cyst. She had required 13 units blood transfusion previously (5 years ago) for massive gastrointestinal bleed with no cause found despite extensive investigations. At operation she was found to have a Meckel's diverticulum in the left lumbar region containing a large calculus. She had an unremarkable post-operative course.
