ABSTRACT

Diagnosis: Tubulovillous adenoma

History: This 59 yo man presents to the clinic for enrollment in the virtual colonoscopy screening protocol.

Findings: A still image from the 3-dimensional endoluminal fly-through of the rectum reveals a raised, broad based, unilobular lesion with smooth contours that projects into the lumen of the rectum. Non-contrast CT cuts in the cross-sectional and axial views from the same level of the endoluminal still image confirms the presence and location of the lesion. The lesion is a well-demarcated ovoid mass projecting in the posterior lumen of the rectum with a broad base. Attenuation homogenous to surrounding soft tissue. » Multimedia Links: • http://rad.usuhs.mil/medpix/multimedia_files/ocvideo.mpg • http://rad.usuhs.mil/medpix/multimedia_files/vcvideo.mpg

Ddx: -Polyp -Colon cancer -lipoma -residual fecal matter (untagged feces) -foreign body -lymphoma

Dxhow: Specimen was biopsed via conventional colonoscopy and analyzed by pathology

Exam: He is at average risk for colonic polyps and colon cancer. He states he is doing well and is in his normal state of health. He denies change in bowel movement, weight loss, or blood in his stool. He has no history of rectal bleeding, hematochezia, or melena. He is without positive stool guaiac test or history of iron deficiency anemia within the past 6 months. The patient has not had prior evaluations for colon cancer screening. His past medical history and family history is unremarkable for adenomatous polyps, colorectal cancer, inflammatory bowel disease, HNPCC or FAPS.

No MeSH data available.


Electronic calipers from virtual colonography program measured lesion as 21.9 X 14.6 mm, 12.3 cm from the rectum. It is elevated, broad based, and unilobular with a smooth surface projecting into the lumen.
