CLOSE-UP view of the CT image:                             Colonoscopic view of the polyp (below):

This 55 yr. old male patient underwent routine sonography of the abdomen. The scan reveals a rounded, solid, soft tissue lesion (isoechoic with the colon) of size 17 x 10 mm, in the lumen of the ascending colon. An atypical target sign is also seen. Color doppler shows a feeder vessel supplying the mass lesion. These ultrasound images suggest colonic polyp. Sonographic images taken using a Toshiba Powervision color doppler machine, courtesy of Dr. Ravi Kadasne, UAE. The polyp was also visualized on CT scan (see images above) and also on colonoscopy (above).

2) Sonography of Colitis:

The above ultrasound images of a child show: 1) multiple enlarged mesenteric lymph nodes (lymph node megaly)     2) gross thickening of the wall of the colon (almost the entire colon seems to be involved) 3) concurrent appendicitis 4) evidence of round worm infestation. This group of ultrasound findings suggest colitis (of infective etiology) with mesenteric lymph node enlargement. Sonographic images courtesy of Dr. Gunjan Puri, Surat, India, who used a Toshiba Xario color doppler and ultrasound system.
