Overview
CT
CT may show erosion and widening of the internal acoustic canal. The density of these tumours on non-contrast imaging is variable, and often they are hard to see, especially on account of beam hardening and streak artifact form the adjacent petrous temporal bone. Contrast enhancement is present, but can be underwhelming, especially in larger lesions with cystic components.
