Abstract:
Two cases of extracranial meningiomas respectively in the left frontal region in a 64-year-old woman and in the right frontal sinus in a 13-year-old boy are reported. Both cases were associated with an intracranial meningioma later detected after primary histologic diagnosis of the extracranial surgical specimen. The possibility of an extracranial meningioma, especially when an angioblastic, fibroblastic or meningothelial pattern is prominent, must always be considered together with the existence of an intracranial equivalent, as our 2 cases clearly demonstrate.
Insights
Extracranial meningiomas can occur with intracranial tumors. Early diagnosis of extracranial meningiomas, particularly those with specific patterns, is crucial for detecting associated intracranial meningiomas.
Area of Science:
- Neurosurgery
- Neuropathology
Background:
- Extracranial meningiomas are rare tumors that can present outside the skull.
- Their association with intracranial meningiomas requires careful diagnostic consideration.
Observation:
- Reported are two cases: a 64-year-old woman with a left frontal extracranial meningioma and a 13-year-old boy with a right frontal sinus meningioma.
- Both patients were subsequently diagnosed with an associated intracranial meningioma.
Findings:
- Histologic patterns such as angioblastic, fibroblastic, or meningothelial in extracranial meningiomas warrant thorough investigation.
- The presence of an extracranial meningioma should prompt evaluation for an intracranial counterpart.
Implications:
- These cases highlight the importance of considering concurrent intracranial meningiomas when diagnosing extracranial variants.
- This underscores the need for comprehensive evaluation in patients presenting with extracranial meningiomas.
