Association Between Cerebrospinal Fluid Leakage and Persistence of Sternberg’s Canal: Coincidence or Cause?

Sternberg's canal as a cause of encephalocele within the lateral recess of the sphenoid sinus: A report of two cases

BACKGROUND Intrasphenoidal encephaloceles are extremely rare findings. Sternberg's canal is a lateral craniopharyngeal canal resulting from incomplete fusion of the greater wings of the sphenoid bone with the basisphenoid. It acts as a weak spot of the skull base, which may lead to develop a temporal lobe encephalocele protruding into the lateral recess of the sphenoid sinus (SS). CASE DESCRI...

Spontaneous sphenoid sinus cerebrospinal fluid leak and meningoencephalocele – are they due to patent Sternberg's canal?

Sternberg's canal is a congenital bony defect in the lateral wall of the sphenoid sinus. If it persists to adulthood, it may become a source of spontaneous cerebrospinal fluid leak (CSF) and meningoencephalocele. The aim of the study was to describe the authors' experience and review articles related to spontaneous sphenoid sinus CSF leaks and Sternberg's canal. We analysed patients managed sur...

Endoscopic transpterygoid approach and skull base repair after sphenoid meningoencephalocele resection. Our experience.

INTRODUCTION AND OBJECTIVES Cerebrospinal fluid leaks associated to meningoencephaloceles of the sphenoid lateral recess are rare entities. A congenital bony defect at this level results in the persistence of Sternberg's canal, or a lateral craniopharyngeal canal, which is supposed to be the origin of these lesions. Our objective was to show that the endoscopic transpterygoid approach is an eff...

Endoscope-Assisted Trans-Sphenoidal Approach for Treatment of Sternberg's Canal

We report an uncommon case of a 45-year-old woman who presented with spontaneous rhinorrhea. A computed tomography (CT) scan of the head revealed an abnormally large sphenoid sinus associated with a parasellar bony defect (Sternberg's canal) through which magnetic resonance imaging could detect an encephalocele of the right temporal lobe. An endoscope-assisted trans-sphenoidal approach was perf...
