Fig. 6

A 64-year-old male patient with heavy bilateral SNHL (case 7). Axial CISS image (a) shows curvilinear T2 hyperintensities (arrow) surrounding the left cochlea. Subsequent axial HRCT image (b) confirms extensive very hypodense plaques (arrows) in the left pericochlear region, likely long-standing disease. Axial CISS image (c) at a lower level also shows a small right IAC diverticulum (dashed arrow), confirmed on subsequent axial HRCT image (d) as an ‘ear-like’ outpouching anterior to the right IAC (dashed arrow). Also note the large plaque in the right FA region (short arrow)
