Abstract:
Atypical meningioma is a rare cause of perineural tumour spread. In this report, we present the case of a 46-year-old female with an atypical meningioma of the skull base demonstrating perineural tumour spread. We describe the imaging features of this condition and its distinguishing features from other tumours exhibiting perineural spread.
Insights
Atypical meningioma, a rare brain tumor, can cause perineural tumor spread. This case highlights its imaging features and differentiation from other tumors with similar spread patterns.
Area of Science:
- Neuro-oncology
- Radiology
- Neurosurgery
Background:
- Atypical meningioma is a rare subtype of meningioma.
- Perineural tumor spread (PNS) is uncommon in meningiomas.
- Skull base tumors can present with complex anatomical involvement.
Observation:
- A 46-year-old female presented with atypical meningioma of the skull base.
- The tumor demonstrated perineural tumor spread.
- Detailed imaging was performed to characterize the spread.
Findings:
- The imaging features of atypical meningioma with PNS were described.
- Distinguishing features from other tumors causing PNS were identified.
- This case illustrates a rare presentation of meningioma.
Implications:
- Improved understanding of atypical meningioma imaging.
- Enhanced diagnostic accuracy for perineural tumor spread.
- Potential impact on surgical planning and treatment strategies for skull base tumors.
