Calcification on the Ventricle Wall Associated With a Shunt Tube

—Case Report—

Abstract

A 53-year-old man with renal failure presented with symptoms of shunt malfunction 11 years after placement of a ventriculoperitoneal shunt. Computed tomography showed high-density lesions on the lateral ventricle wall around the shunt tube. The shunt tube was replaced under monitoring with a neuroendoscope. The resected specimen from the ventricle wall lesion showed calcification and fibrosis. Disturbed calcium and phosphate metabolisms associated with renal failure may have been involved in this abnormal calcification on the ventricle wall.
