A 55-year-old Turkish male presented to the emergency department with complaints of recurrent abdominal pain and vomiting. Free air was detected in abdominal x-ray and abdominal computed tomography (CT). [ncbi.nlm.nih.gov]

Relapsing polychondritis (RP) is a rare systemic disease characterized by an inflammatory process involving predominantly cartilaginous structures. Pneumatosis cystoides intestinalis (PCI) in RP has not been reported previously. [ncbi.nlm.nih.gov]

From the clinical and histological findings, we hypothesized that PCI initially occurred, and intestinal bacterias invaded into vessels through broken mucosal barrier and developed fulminant sepsis. [ncbi.nlm.nih.gov]

A 29-year-old man visited our hospital for right upper abdominal pain. Computed tomography (CT) scan revealed multiple air-filled cysts along the intestinal wall and a pseudokidney sign in the transverse colon. [karger.com]

PCI with pneumoperitoneum induced by α-glucosidase inhibitor is rare, with only 27 cases (excluding the present case) reported in Japan to date. [ncbi.nlm.nih.gov]

The latter is a sign of pneumoperitoneum. (B) An upright view revealed an air-fluid level and pockets of free air under the diaphragm (arrows). [amjmed.org]

[…] cysts, but when these cysts rupture they may produce pneumoperitoneum and hence complicate the clinical scenario. [transbiomedicine.com]

However, neither ischemic change in the colonic wall nor ascites could be seen in the CT scan. Then, we performed an enema with gastrographin. [karger.com]
