A, Contrast-enhanced T1-weighted image in a patient in their 50s with right peripheral facial palsy (PFP) due to cerebral lymphoma showing right cerebellopontine angle lesion merging with the acoustic-facial bundle with enhancement after gadolinium injection. B, Contrast-enhanced T1-weighted image in the same patient showing other hypertense brain lesions. C, Multiple areas of white matter hyperintensity in a woman in her 20s with left PFP due to multiple sclerosis. D, Fluid-attenuated inversion recovery image in the same patient showing hyperintensity of the protuberance, seemingly in the root of the acoustic-facial bundle (arrowhead).Two patients had multiple white matter lesions, including 1 in the nucleus of the facial nerve on the affected side, leading to a diagnosis of multiple sclerosis (MS). No evidence of an alternative cause was identified, and subsequent imaging examinations confirmed the diagnosis (
