[Cystic meningioma. 3 cases].

Area of Science:

• Neurology
• Neurosurgery
• Radiology

Background:

• Meningiomas are common primary tumors of the central nervous system.
• Arachnoid cysts are cerebrospinal fluid-containing sacs that can occur throughout the central nervous system.
• The co-occurrence of meningiomas and arachnoid cysts presents unique diagnostic and management considerations.

Observation:

• This report details three cases involving parameningiomal cysts associated with meningiomas.
• Computed tomography (CT) scans can present diagnostic difficulties in differentiating these entities.
• The study investigates the varied mechanisms contributing to the formation of these cysts.

Findings:

• Parameningiomal cysts represent a specific subtype of cyst associated with meningiomas.
• Understanding the pathogenesis of these cysts is crucial for accurate diagnosis.
• Clinical presentation and imaging findings require careful interpretation to distinguish from other cystic lesions.

Implications:

• Accurate diagnosis of associated cysts impacts surgical planning and patient management.
• Improved understanding of cyst formation mechanisms can refine diagnostic strategies.
• This work highlights practical challenges in the diagnosis of meningioma-associated cysts, informing clinical practice.
