‘DESCENDING COLONIC POLYP’- An ultrasound diagnosis



A boy of about 10 yrs age , having h/o bleeding per rectum and occasional pain left lower abdomen, was examined with high resolution color doppler ultrasound, showed-a well defined round to oval iso to hypoechoic solid mass within lumen of descending colon. The mass appeared bulging within lumen with echogenic mucosal stripe over it , & displacing muscularis propria ,suggesting mucosal or submucosal location [ fig 1& 2]. It also showed few tiny cystic areas in it ,which appeared spokewheel like vasculature on color doppler [see fig 3&4]. Vascular signals are seen within lesion on both color & spectral doppler .No any other abnormality was noted in descending colon wall & rest of the abdomen. On the basis of high resolution ultrasound & color doppler findings a diagnosis of benign intraluminal ‘mucosal-submucosal descending colonic polyp’ was made , which subsequently proved on colonoscopy [ see fig 5] , & resected endoscopically. Biopsy turned out to be benign hypertrophic colonic polyp. By- Dr. Subhash Tailor, MD, Bhilwara [ Rajasthan , India]
