Cerebrospinal fluid rhinorrhea after ventriculoperitoneal shunt in a patient with tectal plate glioma.

Cerebrospinal fluid (CSF) rhinorrhea due to a remote tumor is a rare but increasingly reported condition, where it is usually a presenting complaint. CSF rhinorrhea occurring after tumor decompression has also been reported. We report a patient with tectal plate glioma that caused CSF rhinorrhea following insertion of ventriculoperitoneal shunt. The pathophysiology of CSF rhinorrhea is also discussed. (c) 2009 Elsevier Ltd. All rights reserved.
