    Area of Science:

    • Neurosurgery
    • Radiology
    • Pathology

    Background:

    • Petrous apex lesions are uncommon but can cause significant patient morbidity.
    • Early symptoms are often vague, potentially progressing to cranial neuropathies.

    Purpose of the Study:

    • To detail the experience in treating 69 patients with petrous apex pathologic processes over six years.
    • To aid in preoperative characterization of primary versus secondary petrous apex lesions.

    Main Methods:

    • Review of 69 patient cases treated over a six-year period.
    • Utilized computed tomography (CT), magnetic resonance imaging (MRI), and carotid arteriography for preoperative assessment.

    Main Results:

    • The cohort included 25 primary lesions, 40 by direct invasion, and 4 metastatic lesions.

  • Successful treatment outcomes depend on early diagnosis and thorough preoperative evaluation.

    • Conclusions:

    • Petrous apex lesions require a high index of suspicion for early diagnosis.
    • Appropriate imaging and preoperative assessment are essential for surgical planning and successful patient outcomes.
