Surgical removal of a choroid plexus adenoma using the argon beam coagulator: technical case report.

Abstract

Choroid plexus tumors may be extremely vascular, limiting surgical resection. A case of a choroid plexus adenoma is presented in which the argon beam coagulator (System 6500; ConMed Corp., Utica, NY) was used as a surgical adjunct. A 12-year-old male patient with a giant tumor of the lateral ventricle presented with visual loss and was found to have a large intraventricular tumor. At surgery, the tumor was extremely vascular, and the pathological finding was consistent with a choroid plexus adenoma. Because of its vascularity, the tumor was resected in stages with the aid of the argon beam coagulator. We conclude that this device may have application in selected neurosurgical operations.
