Magnetic Resonance Imaging of Patients With Peripheral Facial Palsy (PFP) Due to Facial Nerve Schwannoma and Facial Nerve Hemangioma 
nerve hemangioma, nerve schwannoma, isointense lesion, T2 hypointensity, Nodular T2 hypointensity
A, Contrast-enhanced T1-weighted image in a patient in their 50s with right PFP due to facial nerve schwannoma showing well-defined nodular contrast in the labyrinthine portion of the right facial nerve (arrowhead). B, Nodular T2 hypointensity in the fundus of the internal auditory canal (arrowhead) in the same patient. C, T1 isointense lesion centered on the lateral part of the geniculate ganglion (arrowhead) in a patient in their 40s with left PFP due to facial nerve hemangioma. D, Intense heterogeneous enhancement after gadolinium injection (arrowhead) in the same patient. E, T2 hypointensity (asterisk) in the same patient.
