Case 1. Image from a right common carotid artery injection demonstrates an aneurysm of the horizontal petrous ICA segment (arrow).
- Fig 3.
Case 2. Image from a right common carotid artery injection reveals a lobulated 3-cm aneurysm of the petrous segment of the ICA.

Case 2. Unenhanced axial (A) and coronal (B) CT images demonstrate a large slightly hyperattenuated soft-tissue mass with smooth scalloped margins, measuring 3 cm in diameter expanding the petrous carotid canal with erosion of the medial wall of the middle ear (arrow).
- Fig 5.
Case 3. Image from a left common carotid artery injection demonstrates a 1.2-cm maximal-diameter wide-necked fusiform aneurysm arising from the anterior curve of the petrous segment of the ICA, projecting posteromedially.
