(18)F-fluorodeoxyglucose positron emission tomography/computed tomography imaging of extra-medullary plasmacytoma of the ovary.

Extrameduallary plasmacytoma of ovary is extremely rare. We report a case of involvement of ovary in a treated case of plasmacytoma of 2(nd) part of duodenum, which was initially thought to be physiological luteal activity. However, follow up whole body FDG PET-CT scan shows appearance of metabolically active soft tissue mass in left adnexal region which confirmed to be extra-medullary plasmacytoma of ovary on histopathology.
