Primary Uterine Cervical Lymphoma Manifesting as Menolipsis Staged and Followed Up by FDG PET/CT.

Primary uterine non-Hodgkin's lymphoma of the cervix is rare. We report a 31-year-old woman presented with menolipsis for 8 weeks. Transvaginal ultrasonography and pelvic MRI detected a solid cervical mass invading the adjacent vaginal wall. The lesion showed obvious FDG uptake on PET/CT scan, and malignancy was considered. It proved to be primary diffuse large B-cell lymphoma of the cervix by biopsy. After 6-cycle R-CHOP chemotherapy, no abnormal FDG uptake was found on another FDG PET/CT scan.
