Sterile cerebrospinal fluid ascites presenting as high SAAG ascites: a case report.

Abstract

BACKGROUND:

Cerebrospinal fluid ascites is a rare complication of ventriculoperitoneal shunting and is the result of infection and subsequent peritonitis in the majority of cases. Sterile cerebrospinal fluid ascites in which no known infectious etiology is identified, is even more unusual.

CASE PRESENTATION:

A 26-year-old female with Loeys-Dietz syndrome and congenital hydrocephalus treated with a ventriculoperitoneal shunt, was evaluated after developing new-onset ascites of unclear etiology after abdominal surgery for repair of an aortic aneurysm requiring multiple therapeutic paracenteses. Her serum ascites albumin gradient (SAAG) was greater than 1.1, suggestive of a portal hypertensive etiology. Gram stain as well as multiple cultures of her ascites fluid were both negative. Extensive investigation including hepatic venous portal gradient measurement and liver biopsy revealed no evidence of hepatic disease or portal hypertension. She was ultimately found to have sterile cerebrospinal fluid ascites which was treated successfully with a peritoneovenous shunt.

CONCLUSION:

Sterile cerebrospinal fluid ascites is a rare clinical entity that has only been reported approximately 50 times in the medical literature. In this report, we also highlight it as a rare cause of high SAAG ascites. Moreover, we describe the use of a peritoneovenous shunt as a novel therapeutic option in the management of this condition.
