  Fig. 1. (A, B) T1-weighted contrast-enhanced magnetic resonance imaging (MRI) scans showed linear enhancement of the right facial nerve (empty arrowhead) and a small nodular enhancement of the left facial nerve (white arrowhead). (C, D) Five years later, T1-weighted contrast-enhanced MRI scans showed a fusiform mass in the labyrinthine segment (white arrowhead) and genu (white arrow) of the left facial nerve.
