Primary meningioma of the middle turbinate: a case report

Area of Science:

• Otorhinolaryngology
• Neurosurgery
• Pathology

Background:

• Meningiomas are tumors arising from meningocytes, typically found in the cranial cavity or spinal cord.
• Sinonasal tract meningiomas are rare and can arise from intracranial extension or primarily within the nasal and paranasal sinuses.
• Primary sinonasal meningiomas are challenging to diagnose due to their infrequent occurrence.

Observation:

• This study reports a rare case of a primary meningioma.
• The tumor was located in the middle turbinate, a previously undocumented site for primary meningioma.
• Histologic examination was crucial for definitive diagnosis.

Findings:

• The case presented is the first documented instance of a primary meningioma originating in the middle turbinate.
• Histopathological analysis confirmed the diagnosis, distinguishing it from secondary extension or other sinonasal tumors.
• The rarity and specific location underscore the diagnostic complexities associated with sinonasal meningiomas.

Implications:

• This case expands the known anatomical distribution of primary sinonasal meningiomas.
• It emphasizes the importance of considering meningioma in the differential diagnosis of sinonasal masses, even in unusual locations.
• Accurate histologic diagnosis remains paramount for appropriate management and understanding of these rare tumors.
