A woman in her 60s presented with mild to moderate trismus and swelling on the left side of the face of a few months’ duration. Her medical history was significant for herpes zoster and self-limited vertigo approximately 3 years prior. Her physical examination was remarkable for left-sided facial swelling. No deficits of the facial or trigeminal nerves were detected. Magnetic resonance imaging (MRI) was performed (Figure).
