Uterine Cervical Metastasis From Primary Rectal Adenocarcinoma on PET/CT and MRI.
FDG avid uterine cervical masses are most commonly due to primary cervical carcinoma; however, history and differential diagnoses are critical when interpreting FDG PET/CT studies. A 51-year-old woman with newly diagnosed moderately differentiated adenocarcinoma of the rectum underwent FDG PET/CT for staging, which revealed the hypermetabolic primary rectal tumor and nodal metastases. Additionally, FDG avid focus in the anterior cervix without a CT correlate was present. Cervical metastasis was suspected, and further evaluation with MRI and histopathologic correlation was recommended, which confirmed cervical metastasis. This case illustrates an unusual case of FDG-avid cervical metastasis from rectal adenocarcinoma.
