18F-FDG PET/CT and MR Findings of Ovarian Carcinoid Within a Dermoid Cyst

Ovarian carcinoid is a rare neoplasm of low-grade malignancy occurring within a dermoid cyst or mucinous tumor, predominantly in perimenopausal women. Reports with radiologic features are scarce. We present a case of a 57-year-old woman with an ovarian carcinoid within a dermoid cyst manifested as a multilocular cystic mass with a solid component showing 18F-FDG PET uptake (SUVmax = 6.02).
