简介
Background
Sternberg's (lateral craniopharyngeal) canal was originally described in anatomic studies as a membranous space in the lateral wall of the sphenoid sinus. The canal has been etiologically associated with lateral sphenoid sinus “spontaneous” cerebrospinal fluid (CSF) leaks. A patent Sternberg's canal has been reported in up to 4% of adults, and persistent vestiges have been reported in up to 30%. However, no modern studies analyzing high-resolution CT scans have been published.
Methods
A consecutive analysis of 1000 high-resolution CT scans of sphenoid bones was performed. Scans were analyzed for a lateral recess, bony defects, arachnoid pits, and holes possibly representing Sternberg's canal. Data were compared with a case series of lateral sphenoid CSF leaks.
Results
Average patient age was 38.7 years (10-92 years). A sphenoid lateral recess was present in 35.3% (17.4% bilateral) of …
