Struma Ovarii: A Case Series and Literature Review of Current Management

Current Management of Struma Ovarii

Abstract

Struma ovarii (SO), also known as ovarian goiter, is a rare monodermal teratoma. About 5-20% of mature teratomas contain thyroid tissue elements, but of these, only 2% are diagnosed as SO. We highlight three cases of large SO with varying clinical presentations and disease progressions. The first case involved a postpartum woman who presented with a ruptured ovarian tumour, while the second case involved a woman who presented with acute urinary retention due to compression by the ovarian mass. The diagnoses of malignant SO were based on histopathological studies in both cases. The third case is a lady with known follicular thyroid carcinoma, who came back with a metastatic left iliac fossa mass and underwent a trial of chemotherapy. As of now, no definite treatment guidelines have been established. A multidisciplinary team approach is needed to manage this rare entity.
