Type 3 JB in a non-hydropic ear. Type 3 is demonstrated in the (a) coronal, b Pöschl and c sagittal planes with the JB above the inferior margin of the PSCC, but below the inferior margin of the IAC, which was imaged at the fundus with the modiolus. A dehiscence was identified between the visualized external aperture of the VA and the upward extension of the JB (a, b and c). Three-dimensional reconstruction computed tomography showing the type II anatomic relationship between JB and VA, where the JB was found to be in close contact with the VA, but the VA was shown intact without obstruction in the (d) posterosuperior and (e) posteroinferior view. f 3D-real IR MRI showing no endolymphatic hydrops in either the cochlea (white arrow) or the vestibule (red arrow), where normal bright perilymphatic fluid was visible. CC, common crus; JB, jugular bulb; JBVAD, JB-vestibular aqueduct dehiscence; PSCC, posterior semicircular canal; IAC, internal auditory canal; VA, vestibular aqueduct; 3D-real IR, three-dimensional real inversion recovery
