An Interesting View

Abstract

This is a 54-year-old female patient with a history of ulcerative colitis. She underwent proctocolectomy and end ileostomy in the 1970s, and now presented with pain around the end of her stoma. The area was biopsied and the pathology report showed an invasive moderately differentiated adenocarcinoma with mucinous features. Subsequently, a PET-CT was performed for initial treatment strategy examination. PET-CT, including volume rendering, demonstrated increased FDG uptake within the stoma site as well as within a loop of bowel traversing through the ostomy tract (maximal SUV is 5.9 and 6.6, respectively). This case is of particular interest, because (1) a volume-rendered PET (only PET—without CT) of such a lesion has not been shown in the literature, (2) this scenario (primary cancer to the stoma detected by PET) is rarely encountered, and (3) these volume-rendered images are useful tools for demonstration of disease sites to clinicians.
