Bilateral Ovarian Metastases From Colon Carcinoma Visualized on F-18 FDG PET Scan

Ovarian metastases (Krukenberg tumor) from primary colorectal carcinoma are relatively uncommon despite the fact that the colon is the most frequent location for gastrointestinal primaries. There are a number of diagnostic and management issues that appear to impact on survival, including timing of definitive diagnosis of Krukenberg tumors such as before, after, or at the same time as diagnosis of the gastrointestinal primary tumor, menopausal status, concurrent pregnancy, role of debulking, and prophylactic oophorectomy. We present a case of bilateral ovarian metastases visualized on fluorine-18-2-fluro-2-deoxy-D-glucose-positron emission tomography (F-18 FDG PET) and CEA Scan using Tc-99m arcitumomab after right hemicolectomy for cecal carcinoma. PET is a useful modality to evaluate for metastases.
