Pneumatosis Cystoides Intestinalis gives many diagnostic and therapeutic troubles especially when it occurs in patient admitted in an emergency setting. The Authors report two cases of PCI related to patients admitted into the Emergency Department (DEA II) with diagnosis of intestinal perforation, mode according to the radiological findings of free subfrenic air, but not confirmed at physical examination. The Authors discuss the role that imaging and physical examination play in evaluating this kind of patients, considering the etiopathogenetic hypothesis about this rare disorder.

Pneumatosis intestinalis (PI) is characterised by pathological gas infiltration into the submucosa and subserosa of the gastrointestinal tract, sometimes with an unclear pathogenesis. The clinical presentation of PI varies, with the diagnosis established via computed tomography (CT), where PI manifests as linear or bubbly gas patterns within the bowel wall. Management often necessitates surgical intervention to address potential life-threatening causes like mesenteric ischemia or bowel necrosis.
