Abstract

Introduction

A mass in the right iliac fossa with pain is often diagnosed as appendicular mass. The differential diagnosis are ileocaecal tuberculosis, carcinoma caecum, intussusception, tuboovarian mass and rarely lymphoma or ectopic kidney. The existence of supernumerary ovary is very rare and has very few case reports. Supernumerary ovary is an additional ovary which has no connection with either the two normal ovaries or the utero-ovarian ligament, broad ligament or the infundibulo-pelvic ligament. Tumours arising from the supernumerary ovaries are extremely uncommon. One such case report is presented for its unusual diagnosis and rarity.
