Fig. 4From: Signal and morphological changes in the endolymph of patients with vestibular schwannoma on non-contrast 3D FLAIR at 3 TeslaA 72-year-old female with left vestibular schwannoma showing serial changes in the perilymph. PPI (a) and HYDROPS (b) display increased signal intensity in the perilymph of the cochlea (small arrow), vestibule (arrow), and semicircular canals (arrowheads) on the affected side. The signal intensity in the perilymph decreased after one year on PPI (c)Back to article page
