benigne Pneumatosis intestinalis

Bening

pneumatosis intestinalis with worrisome radiological findings at first glance. Pneumoperitoneum (green arrow) and air dissecting the fat abdominal planes (yellow asterisk) were incidental findings in this chest X-ray performed for the depiction of a PICC (orange arrow).

Pneumatosis

Intestinalis in HIV and MAC co-infection. On lung windows, the intramural gas seen on the abdominal radiograph was much more conspicuous.

Pneumatosis

Intestinalis in HIV and MAC co-infection. Small bowel wall thickening and gross ascities.

Pneumatosis

Intestinalis in HIV and MAC co-infection. Admission abdominal radiograph shows gross pneumatosis intestinalis of the large bowel. When compared with an earlier abdominal film three months ago, similar but less severe pneumatosis was demonstrated.

Pneumatosis

Intestinalis in HIV and MAC co-infection. Abdominal radiograph three months prior demonstrates less severe pneumatosis.

Pneumatosis

intestinalis versus pseudo-pneumatosis: review of CT findings and differentiation. Pneumoperitoneum in a 66-year-old man with a history of scleroderma and multiple episodes of pneumatosis intestinalis spontaneously resolved in 24 h. a Axial unenhanced CT at a lung window shows pneumoperitoneum (arrow). b Axial unenhanced CT shows oesophageal dilation (arrow), indicating patulous oesophagus associated with scleroderma

Imaging of

intestinal vasculitis focusing on MR and CT enterography: a two-way street between radiologic findings and clinical data. Intestinal vasculitis and benign intestinal pneumatosis in a 52-year-old male with a history of known Scleroderma presenting with abdominal pain. Physical examination revealed generalized abdominal tenderness without rebound or guarding. Upright CXR (A) was done in the ER. Pneumoperitoneum (thick black arrows) was noted at CXR in the absence of signs or symptoms of peritonitis. Due to this discrepancy, abdominal CT scan (B, C) was performed and confirmed pneumoperitoneum (thin black arrow) along with extensive intestinal pneumatosis in the transverse colon (black arrowheads) and jejunum (thick white arrows). The patient underwent conservative treatment. He was discharged one week later with improved signs/symptoms. After three weeks, MRE was obtained and displayed no pneumoperitoneum. Axial T2-W image (D) demonstrates segmental jejunal mural thickening (white dotted oval) with hypointense appearance. Coronal T2-W image (E) shows bowel dilation and the classic hidebound sign (black dotted oval) in the ileum related to known scleroderma. The T2 hypointense segment of thick jejunum is also seen (curved arrows), suggestive of chronic mural thickening perhaps due to fibrosis
