    Area of Science:

    • Neuroimaging
    • Radiology
    • Skull Base Anatomy

    Background:

    • The skull base is a complex anatomical region with vital neurovascular structures.
    • Pathologies in this area are diverse and can present with overlapping clinical and imaging features.

    Purpose of the Study:

    • To highlight the indispensable role of magnetic resonance imaging (MRI) in evaluating skull base pathology.
    • To emphasize how MRI aids in differentiating various disease processes and planning treatment.

    Main Methods:

    • Review of computed tomography (CT) and magnetic resonance imaging (MRI) applications in skull base pathology.
    • Discussion of various MRI sequences for tissue characterization (lipids, paramagnetic/diamagnetic elements, cellularity).
    • Emphasis on high-spatial-resolution MRI for visualizing cranial nerves and adjacent pathology.

    Main Results:

    • CT is useful for evaluating osseous erosion and calcified matrices.
    • MRI is the primary modality for neuroimaging assessment of most skull base pathologies.
    • MRI sequences provide detailed tissue characterization and high-resolution visualization of critical structures.

    Conclusions:

    • MRI is essential for accurate diagnosis and delineation of skull base pathologies.
    • Advanced MRI techniques improve the distinction between various disease processes.
    • Comprehensive MRI examinations are vital for pre-biopsy and treatment planning.
