tentorial angle

The tentorial angle is measured between a line connecting the nasion with the tuberculum sellae and the angle of the straight sinus. Normally it should measure between 27° and 52°.

Abnormalities of the posterior fossa or base of skull can alter this. For example, this angle is elevated in achondroplasia.
