Delayed Recurrent Cerebrospinal Fluid Rhinorrhea due to Transethmoidal Meningocele after Removal of a Convexity Meningioma : A Case Report

Abstract

  Prolonged increase in intracranial pressure due to a slow-growing brain tumor located away from the skull base rarely thins and destroys the skull base, or leads to the development of cerebrospinal fluid rhinorrhea. In most cases, a cranial meningocele or meningoencephalocele with thinning or destruction of the skull base is observed when the tumor is detected. Here, we present a patient with delayed recurrent cerebrospinal fluid rhinorrhea due to a transethmoidal meningocele after removal of a convexity meningioma.
