A 52-year-old woman suspected of uterine sarcoma underwent F-18-FDG PET/MRI, which revealed a myometrial mass and an endometrial lesion, suggesting dual primary neoplasms. Based on the PET/MRI findings, the intraoperative procedure was modified to determine the necessity of pelvic lymphadenectomy. PET/MRI was more useful than PET/CT in diagnosing and differentiating between the two malignant neoplasms in the uterus, due to the high contrast resolution and precise fusion of MRI.
A 52-year-old woman with a rapidly growing uterine tumor suspected of uterine sarcoma underwent F-18-FDG PET/MRI, revealing a myometrial mass and an endometrial lesion, suggesting dual primary neoplasms. Based on the PET/MRI findings, we changed the intraoperative procedure to determine the necessity of pelvic lymphadenectomy. PET/MRI was useful in diagnosing and differentiating between 2 malignant neoplasms in the uterus compared with PET/CT, due to MRI's high contrast resolution and precise fusion due to the simultaneous acquisition.
