Abstract
This report presents a seven-month-old boy with a large abdominal omental cyst containing cerebrospinal fluid (CSF) after VP shunt placement. The VP shunt was placed due to hydrocephalus after intraventricular hemorrhage at age three months. Since six months old, he has been having symptoms of abdominal distension, vomiting, and poor feeding. Abdominal US and contrast-enhanced CT showed a large abdominal cyst enclosing the VP shunt catheter. Through a minimal lower umbilical incision, laparoscopy revealed that the cyst consisted of an omentum filled with CSF. Thereafter, the cyst was extirpated extracorporeally, and the shunt catheter was returned to the peritoneal space. However the omental cyst containing CSF is a very rare condition, and has been reported only in 4 cases in the world to date., It should be noted that differential diagnosis is warranted for abdominal cysts associated with a VP shunt.
