Fig. 4

A 57-year-old female patient with left-sided SNHL (case 3). Axial T1W MR image (a) shows intermediate T1 signal in in bilateral pericochlear regions (arrows). Contrast-enhanced axial T1W MR image (b) and contrast-enhanced coronal T1W MR image (c) show ring-like enhancement in bilateral pericochlear regions (arrows). Contrast-enhanced coronal T1W MR image (d) also shows patchy enhancement surrounding the SCC bilaterally (dashed arrows). Subsequent coronal HRCT images (e, f) confirm otosclerotic plaques adjacent to bilateral lateral SCC (short white arrow), superior SCC (dashed arrow) and in bilateral pericochlear regions (long black arrows)
