18F FDG positron-emission tomography findings of gliomatosis peritonei: A case report and review of the literature

Abstract

•Gliomatosis peritonei (GP) is a rare benign complication of ovarian teratomas that does not impact overall survival.•GP exhibits high 18-F FDG uptake unlike other non-malignant forms of mature teratoma.•The specific characteristics of GP on functional imaging may be used to follow it with active surveillance in select cases.
