A 44-year-old male with a small cholesteatoma (1.9 mm width) in the left tympanic cavity (white arrow). a: Axial T1WI. b: Axial T2WI showing the structure of the small cholesteatoma (white arrow). c: Axial TGSE BLADE DWI (b1000) clearly showing a markedly high signal intensity for the small cholesteatoma (white arrows) without artifacts. e: Axial RESOLVE DWI (b1000) showing the high signal intensity of a small lesion (white arrow) with light geometric distortion and the bilateral middle ear mastoid process with a few artifacts (red arrow). d, f: The ADC values on TGSE BLADE and RESOLVE DWI were 0.737 × 10− 3 mm2/s and 0.984 × 10− 3 mm2/s, respectively
