At the time of his initial presentation, ultrasound showed multilocular fluid throughout the abdomen (Fig. 1), but no hepatosplenomegaly or other secondary signs of portal hypertension.
18-month-old male with large omental cyst. Axial CT with IV and oral contrast demonstrates a large amount of low-attenuation intra-abdominal fluid. The mass effect on the bowel and kidney on the left abdomen suggest a cystic mass lesion. The apparently free fluid also present along the liver persuaded the clinicians to evaluate extensively for a cause for ascites.

The thin septations seen on ultrasound were not visible on CT (Figure 2A, Figure 2B).
18-month-old male with large omental cyst. Coronal CT with IV and oral contrast demonstrates a large amount of low-attenuation intra-abdominal fluid. The mass effect on the bowel and kidney on the left abdomen suggest a cystic mass lesion. The apparently free fluid also present along the liver persuaded the clinicians to evaluate extensively for a cause for ascites.

Repeat CT, approximately nine months after the initial study, showed a recurrent and larger volume of low-attenuation intra-abdominal fluid exerting mass effect upon the bowel loops, which were displaced to the right and downward (Fig. 3A).
18-month-old male with large omental cyst. Axial CT image performed later in the patient's course demonstrates mass effect in the left abdomen as well as central bowel displacement.
