ABSTRACT

Diagnosis: Invasive Colonic Adenocarcinoma: Biopsy of the polyp showed micro-invasive colonic adenocarcinoma, without invasion of the lymphatic, vascular, or perineural space.

History: A 51-year-old male with no known symptoms undergoes with routine screening for colorectal carcinoma with virtual colonoscopy.

Findings: Virtual colonoscopy can create a three dimensional (3D) anatomic model of the colon using data from volumetrically acquired computed tomography (CT) scan (Fig 1A). An axial slice from the CT scan shows a 9 mm pedunculated polyp in the sigmoid colon, approximately 60 cm from the anus (Fig. 2A). A 3D endoluminal view of the colon shows a better depiction of the polyp (Fig. 1B, 2A, 3, 4A). Examples of fly through VC model below (not actual patient): A Flat Hyperplastic Polyp: http://rad.usuhs.mil/medpix/multimedia_files/VC1.avi Sessile Polyp: http://rad.usuhs.mil/medpix/multimedia_files/VC2.avi TVA Severe Dysplasia Polyp: http://rad.usuhs.mil/medpix/multimedia_files/VC3.avi The patient was recommended to undergo optical colonoscopy (OC) to confirm the presence of the polyp. The OC confirmed the presence of a 1.5 cm pedunculated polyp, located 50 cm from the anus (Fig. 4B).

Ddx: • Invasive colonic adenocarcinoma • Intramucosal colonic adenocarcinoma • Adenoma (tubular, villous, and tubulovillous) • Hyperplastic polyp • Fibroblastic polyp • Inflammatory polyp • Lymphoid polyp

Dxhow: Polyp biopsy

Exam: The polyp was biopsied and sent for pathologic diagnosis.
