Pneumatosis Cystoides Intestinalis Discovered During Exploratory Laparotomy

Area of Science:

• Gastroenterology
• Radiology
• Surgical Pathology

Background:

• Pneumatosis cystoides intestinalis (PCI) is a rare condition involving gas-filled cysts in the intestinal wall.
• While typically benign, PCI can present with symptoms mimicking acute abdominal emergencies.

Observation:

• A patient presented with abdominal and back pain, raising suspicion for bowel perforation on CT scan.
• Exploratory laparotomy revealed gas-filled cysts on the small bowel's surface, diagnosing PCI, not perforation.

Findings:

• Distinguishing PCI from free intraperitoneal air on imaging is diagnostically challenging.
• Contrast-enhanced CT is the preferred imaging modality, though diagnosis solely on imaging remains difficult.

Implications:

• Increased awareness of PCI's benign nature and typical imaging findings can aid early detection.
• Improved diagnostic accuracy may prevent unnecessary surgical interventions and improve patient outcomes.
