However, the radiologic imaging features of salivary glands are not yet well known. We report a case of a 56-year-old male patient diagnosed with ICI-induced xerostomia. The patient underwent various imaging examinations to investigate the condition of the salivary glands, which indicated the following: (1) less specific findings on contrast-enhanced computed tomography, (2) mixed with intermediate and low signal intensity on both <jats:italic>T<\/jats:italic><jats:sub><jats:italic>1<\/jats:italic><\/jats:sub>-weighted and fat-suppressed <jats:italic>T<\/jats:italic><jats:sub><jats:italic>2<\/jats:italic><\/jats:sub>-weighted magnetic resonance imaging and poor \u201csalt and pepper\u201d appearance on magnetic resonance sialography, and (3) multiple ovoid hypoechoic areas with hyperechoic bands without acute sialadenitis on ultrasound.
