Facial nerve angioma.

Angioma of the facial nerve is a rare benign tumor. Symptoms include progressive or sudden facial paralysis and, often, a facial twitch. Although angiomas have unique features, diagnosis and treatment is similar to that for facial nerve neuroma. Magnetic Resonance Imaging (MRI) with gadolinium infusion and thin-section Computed Tomography (CT) can often identify the lesion. Treatment by total excision and facial nerve grafting can provide a permanent cure with good restoration of facial function. Four cases are discussed.
