Pneumatosis intestinalis is presence of air in the wall of the intestine. May be referred to as pseudolipomatosis.[1]
Pseudolipomatosis coli directs here. Microvesicular pneumatosis redirects here.
General
- Bad prognosis - esp. if diffuse.
Gross
- Small bubbles in the intestinal wall.
Microscopic
Features:
- +/-Large submucosal pseudocysts - see pneumatosis cystoides intestinalis.
- +/-Vacuolation of the mucosa - fat-like spaces 30-250 micrometres in diameter.[1]
Notes:
- A microvesicular pattern is described - where the voids are 20-200 micrometres.[2]
