1. Review the relevant anatomy of the petrous bone 2. Review pseudolesions, common, and uncommon lesions of the petrous bone along with their CT and MRI findings 3. Help create an algorithm to help the radiologist narrow the differential diagnosis of common petrous bone lesions taking into account the relevant clinical history and imaging characteristics  

- Petrous bone anatomy - Different classifications of petrous apex lesions: etiology vs. imaging characteristics - Algorithm for narrowing the differential diagnosis of common petrous bone lesions - Sample cases and review of CT and MRI imaging findings:      o Nonexpansile lesions      o Expansile nonaggressive lesions of the petrous apex      o Expansile aggressive lesions of the petrous apex
