Pneumatosis cystoides intestinalis (PCI) is a rare entity characterized by the presence of gas within the intestinal wall; it may be classified as primary/idiopathic or secondary.

PCI usually remains asymptomatic and often represents animaging incidental finding.

The presence of symptoms mostly depends on the site of bowel involvement, mass effect or related complications. Imaging still plays a key-role not only in establishing the correct diagnosis but also in assessing the presence of comorbidities or complications.

Ultrasound (US) is mostly used in the pediatric population while in the adult population X-rays may be the first approach. Computed tomography (CT) is always the preferred study for diagnosis, differential diagnosis and follow-up.

It allows accurate visualization of intramural gas in cystic or linear configuration and helps avoid unnecessary surgical intervention by identifying associated high-risk features.

The aim of this case report is to show a rare benign situation of PCI in a young man who presented to our emergency room (ER) after a blunt trauma.
