The sphenoid tumoral pathology

The interest and difficulty of sphenoid tumor imaging relate mainly to its great diversity. Detection may be difficult due to variable tumor size and often misleading clinical data. Because the sphenoid is located at the center of the skull base, tumor extension may be quite variable and difficult to assess, requiring sufficient knowledge of anatomy and imaging features to detect tumor spread, especially retrograde perineural spread, since this has a negative impact on prognosis.
