Case Discussion

CT features in this case are of gross abdominopelvic ascites. However, no pseudocyst or collection formation around the tip of the VP shunt is seen.

The peritoneum is thickened and shows significant enhancement that suggests an infective process which is the most common cause of VP shunt malfunction in pediatrics.
