Imaging of Skull Base Tumors

Area of Science:

• Radiology
• Oncology
• Neurosurgery

Background:

• Incidental diagnosis of skull base tumors is increasing due to advanced cranial imaging.
• Tumor origin influences displacement and anatomical involvement patterns.
• Management decisions require careful consideration of observation versus treatment.

Purpose of the Study:

• To provide an overview of imaging modalities for common skull base tumors.
• To detail imaging findings associated with these tumors, including meningiomas.
• To guide surveillance and treatment decisions using imaging features.

Main Methods:

• Review of imaging modalities (CT, MRI, CT angiography) for skull base tumors.
• Analysis of characteristic imaging findings related to tumor origin and invasion.
• Discussion of quantitative imaging analyses like radiomics for future applications.

Main Results:

• Combined CT and MRI analyses enhance diagnostic accuracy for skull base tumors.
• Imaging clarifies tumor origin, extent of bony invasion, and vascular encroachment.
• Specific imaging features aid in planning treatment and surveillance strategies.

Conclusions:

• Imaging plays a crucial role in the diagnosis and management of skull base tumors.
• Understanding imaging findings is essential for guiding clinical decisions.
• Future quantitative analyses may offer deeper insights into tumor biology.
