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

ZStruma 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.
