Interstitial pneumonia on baseline 1 year ago with subpleural reticulations in basal and apical regions and thickenings on both apices; NSIP (non-specific interstitial pneumonitis) pattern.
Findings that are likely related to superadded acute sepsis: bilateral ground glass, consolidation and ill-defined centrilobular nodules.
Stable, on serial CTs, gastrointestinal findings: oesophageal dilatation, pyloric, duodenal and jejunal mucosal thickening, with a D1 diverticulum and well-seen valvulae conniventes. Stable enteric and proximal colonic (caecum, ascending and transverse colons) dilatation without discrete transition point, identical to previous CTs (not shown). Descending and sigmoid colons and the rectum are not dilated. Overall picture most likely an adynamic bowel.
Concurrent acute sepsis, coupled with dilated bowel of 6cm and mild free fluid, raised suspicion for toxic megacolon. Normal bowel enhancement.
