Abdominal cerebrospinal fluid (CSF) pseudocyst presented with inferior vena caval obstruction and hydronephrosis

Abdominal cerebrospinal fluid (CSF) pseudocyst is an uncommon complication of ventriculo-peritoneal shunt placement. A large pseudocyst may exert a significant pressure effect, but vascular or urological symptoms are extremely rare. We report an unusual case of a CSF pseudocyt causing inferior vena caval and ureteric obstruction.
A 14-year-old girl had previously undergone ventriculo-peritoneal shunting for congenital hydrocephalus. She developed bilateral ankle edema as the only presenting symptom of a large non-infected cerebrospinal CSF pseudocyst. The associated abdominal distension was initially attributed to obesity, and the patient was unable to communicate due to developmental delay. Imaging studies showed that the pseudocyst was causing inferior vena caval obstruction and bilateral hydronephrosis. The ankle edema and hydronephrosis resolved after aspiration of the pseudocyst and shunt revision.
Children who require CSF shunting may suffer from associated developmental delay and are frequently unable to communicate their symptomatic complaints. This case illustrated the importance of a heightened clinical suspicion in managing these patients in whom shunt failure may present with subtle and obscure signs of lower body venous congestion.
