Computed tomographic imaging of meningiomas.

Area of Science:

• Neurosurgery
• Radiology
• Oncology

Background:

• Magnetic resonance imaging (MRI) is often preferred for brain tumor imaging.
• Meningiomas can invade adjacent bone, causing hyperostosis.
• Surgical planning for meningiomas requires detailed anatomical information.

Purpose of the Study:

• To highlight the indispensable role of computerized tomography (CT) in meningioma surgical resection.
• To emphasize CT's utility in evaluating bone invasion and planning surgical approaches.
• To demonstrate CT's value in vascular assessment and postoperative defect repair.

Main Methods:

• Review of CT imaging characteristics in meningioma cases.
• Analysis of CT's contribution to surgical planning and intraoperative guidance.
• Evaluation of 3D-CT in the design of cranial prostheses.

Main Results:

• CT provides superior bone definition, crucial for assessing meningioma invasion and hyperostosis.
• Advanced CT techniques visualize adjacent vasculature, informing resection feasibility and adjuvant treatment planning.
• High-resolution and 3D-CT are vital for skull base tumor surgery and reconstructive procedures.

Conclusions:

• Computerized tomography (CT) remains a critical preoperative and postoperative tool for meningioma surgical resection.
• CT's bone and vascular imaging capabilities enhance surgical planning, especially for skull base meningiomas.
• 3D-CT imaging is essential for planning reconstructive surgery following tumor resection.
