Patient imaging studies from the present series. A and B, Contiguous, axial, T1 fat-suppression post gadolinium images with no enhancement in the left internal acoustic canal. C-F, Axial (C and D) and oblique sagittal (E and F) reformatted 3D-FLAIR (3-dimensional fluid-attenuated inversion-recovery) images before (C and E) and after (D and F) gadolinium administration showing enhancement of the left cochlear nerve consistent with blood-nervous barrier breakdown after gadolinium administration (white arrows).

Patient imaging studies from the present series. A and B, Fast-spin echo T1 axial images before (A) and after (B) gadolinium administration with fat suppression showing mild hyperintense signal of the middle gyrus of the left cochlea without enhancement after gadolinium administration owing to methemoglobin deposition from hemorrhage. C and D, Three-dimensional FLAIR (fluid-attenuated inversion-recovery) axial images before (C) and after (D) gadolinium administration showing diffuse, nonhomogeneous hyperintense signal within the middle and apical gyrus of the cochlea on the left, without enhancement.

Patient imaging studies from the present series. A and B, FIESTA (fast-inflow steady-state acquisition) axial images showing normal signal of labyrinthine fluid. C and D, T1 fast-spin echo axial images before (C) and after (D) administration of gadolinium with fat suppression showing normal labyrinthine signal (C) and very doubtful mild enhancement of the cochlear fluid (D). E-H, Three-dimensional FLAIR (fluid-attenuated inversion-recovery) axial images before (E and F) and after (G and H) gadolinium administration showing hyperintense signal of the labyrinthine fluid (E and F) with strong enhancement (G and H). Note the lack of signal from the labyrinth in the unaffected side. Date of download: 10/27/2017 Copyright © 2013 American Medical Association. All rights reserved.
