Recurrent Ovarian Granulosa Cell Tumor

Female patient, 58 years old, was admitted to the hospital with a pelvic mass found for 7 days, 4 years after chemotherapy after ovarian granulosa cell tumor cytoreductive surgery. Postoperative pathology after cytoreductive surgery 4 years ago: left ovarian adult granulosa cell tumor, involving the uterine seromuscular layer and serous layer of the left fallopian tube. No tumor metastasis was found in the pelvic lymph nodes and greater omentum. Ultrasonography examination showed that the whole uterus and bilateral adnexa had been removed. Pelvic effusion: anechoic area above the vagina, 72 mm × 62 mm × 17 mm in size. A mixed echo area of 93 mm × 65 mm × 58 mm was found on the right side of pelvic cavity, with abundant color blood flow; a moderate hypoechoic area was found on the posterior wall of the bladder protruding to pelvic cavity: 25 mm × 26 mm × 16 mm, with punctate color blood flow. Weak echo area was seen on the left side of pelvic cavity: 23 mm × 21 mm × 23 mm, with colored blood flow in the margin. PET-CT: ovarian postoperative change; solid and cystic mass and multiple nodules on the right side of pelvic cavity, with partially increased FDG uptake; and metastasis were considered. Postoperative pathological result: the stump of greater omentum, bladder apex mass, the mass of the anterior wall of sigmoid colon, and the mass of rectouterine pouch, consistent with recurrence of ovarian granulosa cell tumor in correlation with medical history.
