Figure 1.
A pleomorphic adenoma located in the superficial lobe of the left parotid gland of a 63-year-old male. (A) Axial T1WI showed a round mass with isointense signal intensity and hypointense capsule. (B) Axial T2WI sequences with fat suppression showed the lesions with inhomogeneous hyperintense signal. (C) ADC map showed the mass alternated with red or yellow signal. The ADC value was 1.84 × 10−3 mm2 s–1. (D-E) Time-signal intensity curve showed a persistent pattern (Type A). (F) HE staining: original magnification, 100×. ADC, apparent diffusion coefficient; HE, hematoxylin; T1WI, T1 weighted imaging.
