18F-FDG PET/CT Findings of Ovarian Myxoid Chondrosarcoma

Abstract

Ovarian myxoid chondrosarcoma is a rare and aggressive tumor. We present 18F-FDG PET/CT findings of ovarian myxoid chondrosarcoma. The images not only demonstrated a pelvic mass with increased FDG uptake, but also a mass with increased FDG uptake in the right lower abdominal wall. Ovarian malignancy with abdominal wall metastases was suspected. An extraskeletal myxoid chondrosarcoma was diagnosed histopathologically after the mass excision.
