CT scan of the abdomen shows intramural gas within the colon wall, consistent with pneumatosis coli. Courtesy of Dr. [Contributor’s Name].

Differential Diagnosis Table (TCV Disease Categories)

Disease	TCV Category	Reasoning
Bowel ischemia	Circulatory	Most critical cause; pneumatosis indicates compromised blood supply and impending infarction
Infectious colitis (e.g., C. difficile)	Infectious	Severe mucosal inflammation may lead to gas-producing organisms entering the bowel wall
Pneumatosis cystoides intestinalis	Mechanical / Functional	Benign, chronic form often seen in COPD, steroids, or after endoscopy
Necrotizing enterocolitis (NEC) (peds)	Infectious / Circulatory	Pediatric emergency; occurs in neonates due to ischemia + infection synergy
Post-endoscopic or surgical intervention	Iatrogenic	Air introduced via instrumentation; generally benign and self-limited
Steroid/immunosuppressive therapy effect	Metabolic / Iatrogenic	May weaken mucosa or promote gas formation in bowel wall
