Abstract
Mature cystic teratoma is a relatively common tumor of the ovary. It makes up 10–15 % of all ovarian tumours and tends to occur at a relatively early age. Except for functional ovarian tumors, the other lesions from the ovary are usually asymptomatic and usually present with mechanical symptoms from the mass lesion. We present a case of a mature cystic teratoma presenting with small intestinal obstruction with x-ray suggesting a radioopacity in the right iliac fossa.
