Incidental Finding of an Ovarian Carcinoid on 11C-Methionine PET/CT

Abstract

A 68-year-old woman with a history of multiple myeloma on regular hematological follow-up and with no previous relevant gynecological diseases was found to have an incidental focal uptake by the right ovary at ¹¹C-methionine PET/CT (C-MET). Transvaginal ultrasound was then performed showing a 2-cm solid right ovarian mass with irregular borders and moderate vascularization at color Doppler examination. Therefore, the patient underwent bilateral salpingectomy, and the final histological results revealed a rare presentation of mature teratoma with insular carcinoid tumor arising from the right ovary.
