Pneumatosis cystoides coli
Left and Center: Nodular, polypoid mucosal lesions discovered in an 84 year-old
woman undergoing colonoscopy for evaluation of constipation. She was otherwise asymptomatic.
Many of the lesions were erythematous.
Right: Biopsy revealed the lesions to have an internal
cystic appearance, suggestive of pneumatosis cystoides intestinalis.
The diagnosis was confirmed
histologically:
61 year-old asymptomatic man undergoing routine high-risk colon screening in view of a family history of colonic carcinoma.
Colonoscopy revealed soft, benign-appearing nodular lesions. Biopsies confirmed the suspicion of pneumatosis.
52 year-old asymptomatic woman undergoing colonoscopy for average risk colon screening. Numerous soft polypoid lesions were seen scattered throughout the colon. Biopsies were consistent with pneumatosis.
