Rare case of bilateral petrous apex cephalocele.

The petrous apex is a pyramidal-shaped structure which is difficult to examine due to difficult anatomical location. Lesions in the petrous apex can be managed surgically or they can be incidental lesions, which are managed conservatively. Petrous apex cephaloceles (PAC) are the cystic lesion due to herniation in the Meckel's cave of temporal bone.
