An unusual case of small bowel volvulus due to pneumatosis cystoides intestinalis: Case report and literature review

INTRODUCTION AND IMPORTANCEPneumatosis cystoides intestinalis (PCI) is an uncommon condition characterized by intramural gas accumulation in the intestinal submucosa. Idiopathic or secondary is presented with non-specific clinical signs; in some cases, diagnosis is incidental. Its acute presentation is uncommon, and surgical management could be performed in selected cases.CASE PRESENTATIONWe present the case of an 85-year-old woman with 3 days of abdominal pain, 6 months of weight loss, and abdominal distension after meals. Abdominal computed tomography evidenced PCI at the small intestine with changes due to intestinal ischemia and internal mesenteric hernia. Intestinal resection and lateral-lateral mechanical anastomosis were performed with no complications after 90 days of follow-up.CLINICAL DISCUSSIONPCI is an infrequent and benign condition; pathophysiology is, to date, poorly understood. Idiopathic or secondary to other gastrointestinal pathologies are described. The final diagnosis is performed with histopathological analysis. Nevertheless, in some cases, the benign nature could be presented as an acute abdomen, and surgical management should be in the physician's armamentarium.CONCLUSIONPCI is an uncommon and benign entity. Nevertheless, in some cases, it could be presented as an acute abdomen. The surgical approach is appropriate, safe, and feasible.
