Specializes in Psychiatry

Petrous Apex: Most common possible cause is chronic otitis media (middle ear infections), as i recall from my medical school days. Please review with the radiologist & an ENT specialist.

Petrous apex: Could also be a cholesterol granuloma. These lesions, if asymptomatic, usually just need to be monitored with MRI to check for any changes in size.
