A 66-year-old male patient with no specific prior medical history consulted due to constipation without other associated symptoms. A colonoscopy was performed and multiple pseudonodular lesions were detected from the sigmoid to splenic angle in the form of air bubbles with normal-appearing mucosa and a preserved vascular pattern. Gas was released when the biopsies were being taken. An abdominal computed tomography (CT) scan was performed due to the suspicion of an idiopathic or primary intestinal pneumatosis, in which the findings confirmed the diagnosis.
