Abstract

Struma ovarii is a rare ovarian tumor and a monodermal variant of dermoid tumors of the ovary in which thyroid tissue components constitute more than 50% of the mass. Struma ovarii accounts for 0.5–1.0% of all ovarian tumors and 2-5% of ovarian teratomas. Most cases are benign, but malignant transformation is found in a small percentage. It usually presents as a unilateral adnexal mass at fifth and sixth decades of life, with symptoms like other ovarian tumors. The definitive diagnosis is made by histological examination. Adnexectomy remains the standard line of treatment for benign disease. A 41-year-old lady presented with pain in abdomen for 3 months. On ultrasonography and MRI, a multiloculated solid cystic lesion of 7×6 cm with internal echoes was found in the right adnexa. Laparoscopic right adnexectomy was performed. Histopathology was consistent with struma ovarii. Due to its vague clinical manifestations and diverse imaging characteristics, pre-operative diagnosis is challenging.
