Abstract

Background: Abdominal pseudocyst (APC) is an uncommon manifestation of a ventriculoperitoneal (VP) shunt that is attributed to an inflammatory response, usually the result of infection.

Case description: A 13-year-old girl with a VP shunt presented with progressive abdominal distention, pain and vomiting. The shunt was inserted at infancy for congenital hydrocephalus. A shunt infection was treated with externalization of the shunt, antibiotics and subsequent shunt replacement. At the age of four, the shunt was revised for a distal malfunction. Nine years later, abdominal CT and ultrasound demonstrated large multiseptated cysts. The shunt was externalized and 1.8 L of sterile, xanthochromic peritoneal fluid was drained. The cerebrospinal fluid was clear, colorless, acellular and sterile with normal protein and glucose levels. Two days later, the distal portion of the shunt was replaced back into the pleural cavity. Five months later a pleural effusion formed. Thoracentesis was performed and there was no evidence of infection. The shunt was subsequently converted to a ventriculoatrial system. The patient has remained well for over 3.5 years.

Conclusion: APC represents an important complication of VP shunts, with an unclear etiology that can occur nine years after shunt surgery. This paper presents an update on the management of APCs.
