WWWTP #23 (What’s Wrong With This Picture?) Answer


Patient presented with cough, fevers.  This Chest Xray was obtained:

WWWTP 21 1

One finding on this Xray is very concerning.  The Xray showed free air under the diaphragm.

A further diagnostic study was obtained (CT abdomen/pelvis):

WWWTP 21 2 WWWTP 21 3

Turns out this patient has pneumatosis cystoides intestinalis.  He has a history of this disorder and has had a prior laparoscopy showing multiple cystic structures in the intestinal walls.

Findings on imaging:

1.  Chest Xray:  Concern for free air underneath the diaphragm.  He also has a tracheostomy, pacemaker, scoliosis, and a right lower lung infiltrate.

2.  CT abdomen/pelvis:  The coronal imaging shows multiple cystic structures full of free air in the cecal area.  The cross-sectional imaging above shows a large amount of pneumoperitoneum.

Luckily this patient has a history of pneumatosis cystoides intestinalis.  He has had multiple abdominal CT’s showing similar findings.  Clinically he had no abdominal tenderness.  Keep this rare diagnosis in mind for the patient presenting with free air in the abdomen!  Information about pneumatosis cystoides intestinalis:
