This case report describes a 6-year-old girl who developed four colonic intramural hematomas, identified as vascular lesions, as a complication of a diagnostic colonoscopy. The lesions, initially concerning for angiodysplasia, resolved completely within three months without further intervention.
A 6-year-old girl with chronic constipation underwent a diagnostic colonoscopy to exclude a rectal polyp. The procedure was prolonged due to poor bowel preparation and looping in the sigmoid colon. On withdrawal, four raised, purple vascular lesions were visualized. Initial workup for angiodysplasia or syndrome was negative. A repeat sigmoidoscopy 3 months later showed complete resolution of the lesions. The report concludes the lesions were most likely intramural hematomas from procedural trauma. The implications suggest recognizing this rare complication to avoid unnecessary extensive evaluations.
