Plain film of the abdomen shows soft tissue fullnees in the pelvis. Ultrasound confirmed large fluid collection of CSF with shunt in the middle of the collection
CSF-oma is a loculation of cerebrospinal fluid (CSF) at the distal end of the Ventriculoperitoneal shunt tube.
It may occur secondary to adhesions and results in an enlarging abdominal and or /pelvic mass at the catheter tip, as CSF from the tip is no longer absorbed by the peritoneum.
CSF-oma can resolve spontaneously or after shunt revision or repostion.
Complications include infection and obstruction.
Infection rate is 30% and can be higher in younger children.
Causes of Shunt Malfunction:
Mechanical failure of the shunt
Obstruction
Disconnection
Migration
Equipment failure
Fracture of tubing
Shunt infection
Locations of Shunt Catheter Migration: Scrotum
Internal jugular vein
Umbilicus
Stomach
Mouth
Vagina
Intestine
Chest
Liver
Anus
Coronary sinus
