Peritoneal shunt tube migration into the stomach--case report--.

A 47-year-old man presented with repeated headache and feverishness 3.5 years after undergoing ventriculoperitoneal shunt surgery for normal pressure hydrocephalus secondary to subarachnoid hemorrhage. Abdominal computed tomography revealed that the peritoneal catheter was encased by fibrous tissue and the distal end of the catheter had migrated into the stomach. The diagnosis was spontaneous gastric perforation by the ventriculoperitoneal shunt. The fibrous tissue was expected to seal the very small gastric perforation, so the catheter was successfully extracted through a scalp incision without abdominal surgical intervention.
