Imaging of the central skull base

Area of Science:

• Radiology
• Anatomy
• Pathology

Background:

• The central skull base (CSB) is an intricate anatomical region connecting the extracranial head and neck with the middle cranial fossa.
• It contains numerous foramina and canals housing critical neurovascular structures, serving as potential pathways for disease spread.
• Lesions in the CSB can originate intrinsically, intracranially, or extracranially.

Purpose of the Study:

• To provide a systematic, anatomy-based approach for evaluating central skull base lesions.
• To highlight the indispensable role of cross-sectional imaging in the diagnosis, treatment planning, and follow-up of CSB pathologies.

Main Methods:

• Review of the complex anatomy of the central skull base.
• Discussion of potential origins and spread patterns of CSB lesions.
• Emphasis on cross-sectional imaging techniques.

Main Results:

• A systematic approach to CSB evaluation based on its major tissue constituents is presented.
• Cross-sectional imaging is crucial for comprehensive assessment of CSB lesions.
• Understanding the anatomical relationships is key to identifying lesion origin and extent.

Conclusions:

• A structured, anatomical approach aids in the effective diagnosis and management of central skull base lesions.
• Cross-sectional imaging is essential for delineating the complex CSB and associated pathologies.
• This review offers a framework for radiologists and clinicians managing CSB diseases.
