title: Parotid gland metastasis originating from malignant meningioma.
abstract: A case of malignant meningioma with metastasis to the parotid gland is reported. A 60-year-old woman with right-sided neurological symptoms secondary to malignant meningioma developed bilateral parotid masses with identical histology to the primary lesion. The primary lesion was differentiated from a benign oligodendroma with MRI, and the radiological features of this extraordinarily rare metastasis are chronicled with MRI and computed tomography.
