Abstract
|
|
|
|
18F-FDG avid polypoid or tumefacient carcinomas of the gastrointestinal (GI) tract including the rectum are haracteristically featured on PET-CT as an intraluminal tumor surrounded by completely or partially cleared background.1) However, the carcinomas of intramural or sessile variant may not so easily be detected especially when tumors are obliterated by feces or mucus retained in the host bowel loop. Recently, we observed a case of cauliflower-like adenocarcinoma of the rectum that was diagnosed by noting a subtle, flat filling defect created against the background of “black" feces-mucus filled rectum. To our knowledge such a "filling defect" produced by sessile tumor has not previously been reported as a useful diagnostic sign of GI tract carcinoma on PET-CT.
