The T2-weighted images were unremarkable, but the T1-weighted images axial (Fig 1) and coronal (Fig 2) demonstrated bilateral strikingly abnormal high signal material precisely outlining and filling in the cochlea, vestibule, and portions of the semicircular canals. The post-contrast T1-weighted images showed no evidence of associated abnormal enhancement.
Coronal T1-weighted (TR 600, TE 30) 3mm noncontrast sections through the inner ear. Arrows indicate hemorrhage within the labyrinth. [Powerpoint Slide]
