Abstract:
A case of primary meningioma of the nasal cavity and ethmoidal sinus of a 65-year-old man is described. The clinical and pathologic characteristics of the 18 cases previously reported in the literature are reviewed. Although the histological features and biological behavior of the tumors were found to be similar to that of intracranial meningioma, primary meningiomas of the nasal cavity and paranasal sinuses were found more often to involve male patients and young individuals. Meningiomas should be considered in the differential diagnosis of any lesion in a young patient with progressive exophthalmos, nasal obstruction, or episodes of epistaxis. The pathogenesis of extracranial meningiomas is briefly discussed.
Insights
Primary meningiomas of the nasal cavity and paranasal sinuses are rare tumors. This review highlights their clinical and pathological features, noting similarities to intracranial meningiomas but differences in patient demographics.
Area of Science:
- Neuro-oncology
- Otorhinolaryngology
- Pathology
Background:
- Primary meningiomas of the nasal cavity and paranasal sinuses are uncommon neoplasms.
- Understanding their characteristics is crucial for accurate diagnosis and management.
Observation:
- A case of primary meningioma in a 65-year-old man affecting the nasal cavity and ethmoidal sinus is presented.
- Review of 18 previously reported cases provides insights into clinical and pathological features.
Findings:
- Histological features and biological behavior resemble intracranial meningiomas.
- Extracranial meningiomas in this location appear more prevalent in younger males.
- Common presenting symptoms include progressive exophthalmos, nasal obstruction, and epistaxis.
Implications:
- Meningiomas should be included in the differential diagnosis for sinonasal lesions, especially in young patients with suggestive symptoms.
- Further research into the pathogenesis of extracranial meningiomas is warranted.
