Hepatic pseudocyst of cerebrospinal fluid

Ventriculoperitoneal shunt is one of the most frequently performed surgeries in the treatment of hydrocephalus. Perforation of a solid abdominal organ, and subsequent development of the hepatic spinal fluid pseudocyst, is a rare but important complication of the procedure. There are predisposing factors for this complication, including infection, obstruction or displacement of the shunt. However, the presence of abdominal inflammatory processes is widely accepted as the hypothesis for the formation of the liver pseudocyst. The most frequent symptomatology is pain, bloating, tenderness, and abdominal mass, making the diagnosis difficult because they have clinical and radiological characteristics similar to other abdominal pathologies. Neurological symptoms suggestive of a ventriculoperitoneal shunt dysfunction are rare and appear later. Ultrasound and computed tomography of the abdomen are the imaging studies of choke to diagnose this condition. Therapeutic protocol is controversial. Standard treatment, in cases where there is no evidence of infection or peritoneal inflammatory reaction, is repositioning of the peritoneal catheter. Formation of a pseudocyst should always be considered in patients with a ventriculoperitoneal shunt. A case of hepatic pseudocyst of cerebrospinal fluid is presented.
