A 64-year-old obese woman underwent ventriculoperitoneal shunting for hydrocephalus associated with subarachnoid hemorrhage. On the 10th postoperative day, the distal end of the peritoneal catheter migrated into the abdominal wall and she developed a cyst filled with cerebrospinal fluid around the migrated catheter. The distal end of the catheter was surgically repositioned. We attribute the migration to increased intra-abdominal pressure due to obesity, the use of a low friction hydrogel-processed peritoneal catheter, and the presence of a large dead space around the catheter. The laparotomy must be closed meticulously to prevent this type of migration.
