title: Primary extracranial meningioma of the sinonasal tract.
abstract: Meningiomas occurring outside the cerebrospinal axis can be primary at an extracranial site (nasal cavity, paranasal sinuses, and nasopharynx) or secondary extending from an intracranial lesion. Magnetic resonance imaging findings of an 8-year-old child with primary meningioma before and after surgery have been reviewed and compared to computed tomography and histological evaluation. The child had difficulty breathing through the left nostril and tearing of the left eye. After physical and radiological examination, a tumor comprising the left lower, middle turbinate, and ethmoidal cells was found and radically extirpated. On histological examination, the tumor was identified as meningothelial meningioma. On the basis of the clinical, radiological, and histological features, the tumor was diagnosed as extracranial meningioma of the sinonasal tract. A follow-up examination 6 months later revealed no evidence of recurrence of the tumor.
