Fig 1 — MR imaging findings. The known lesion (arrowhead) demonstrates low signal intensity on the T1-weighted axial image (A) T2-weighted axial image (B) and short tau inversion recovery (STIR) coronal image (C) show high signal intensity at the periphery and low signal intensity (arrows) in the center of the lesion. The apparent diffusion coefficient (ADC) map (D) reveals an ADC value of 1.4 × 10-3 mm2/s in the central portion of the lesion (arrow), which corresponds to low signal intensity region on T2-weighted image or STIR. The 3D double-echo steady-state with water excitation oblique-sagittal image (E) and oblique-coronal image (F) demonstrates continuity (arrows) between the mass lesion and the facial nerve.
