Acute colocolic intussusception is a rare in the pediatric population and generally involves a pathologic lead point, which usually necessitates surgical or endoscopic intervention. No prior published reports have demonstrated presurgical imaging findings of colonic polyp in cases of pediatric colocolic intussusceptions. We will present two pediatric cases from our institution that feature colocolic intussusception with an intestinal polyp as a lead point, with a goal to demonstrate specific sonographic and MR findings.

Congenital urethral polyps are a rare benign fibroepithelial lesion, typically arising from the verumontanum. We present a case of a 2 day old neonate undergoing renal ultrasound for follow up of prenatally diagnosed urinary tract dilation. Ultrasound demonstrated severe bilateral central and peripheral caliyectasis with parenchymal thinning, bilateral distal ureterectasis and marked bladder wall thickening. An echogenic soft tissue nodule was visualized at the bladder outlet. Subsequent VCUG showed a rounded filling defect intermittently located in the posterior urethra and bladder neck, suspicious for a diving mobile polyp. Transurethral resection of the polyp was performed. This case highlights an unusual cause of bladder outlet obstruction in neonates which can mimic the presentation and imaging appearance of posterior urethral valves. Read More

While there are various intestinal polyposis syndromes, the single juvenile retention polyp (JRP) is one of the most common polypoid lesions detected in the pediatric gastrointestinal tract. Although these solitary JRPs are benign entities, they can commonly present with hematochezia. Rarely, they can serve as a nidus for infection. While intestinal polyps are fairly frequently encountered by endoscopy, they are not commonly encountered radiologically.

The subject of this case report is an 8 year old female who experienced intermittent abdominal pain and hematochezia for approximately one year before ultimately presenting with sepsis and colitis. By radiograph, CT, endoscopic sampling, histopathologic and laboratory evaluation, she was found to have sigmoid colitis secondary to a solitary JRP.

Initial abdominal radiograph showed haustral thickening, raising suspicion for colitis. Subsequent contrast enhanced abdominopelvic CT revealed a 2.8 cm peripherally enhancing, centrally hypodense polypoid lesion with internal calcification in the sigmoid colon. There was adjacent colonic wall thickening and mesenteric stranding suggesting an associated infectious or inflammatory process.

Stool studies were positive for enteropathogenic E. Coli and occult blood. The colonic lesion was endoscopically excised and shown to be a JRP. This was the presumed nidus for hematochezia and eventual bacterial translocation leading to colitis. The patient was treated with supportive and antimicrobial therapy, and ultimately improved to her baseline status.

While solitary juvenile retention polyps are non-neoplastic entities, they can often present with hematochezia and rarely serve as a nidus for colitis which may lead to sepsis. If a solitary polypoid lesion is identified in a region of intestinal inflammation, it should be considered as a potential culprit. Read More
