1 A 48-year-old woman with a carcinoma ex pleomorphic adenoma (case 1).
A 48-year-old woman with a carcinoma ex pleomorphic adenoma (case 1). A, Axial T2-weighted image (fast spin-echo: TR/TE, 4102/90) shows a well-demarcated mass with heterogeneous intensity of the right parotid gland. The lateral component shows mild high intensity (arrow), the intermediate component shows low intensity (arrowhead), and the medial component shows extremely high intensity (curved arrow). B, ADC mapping image shows the lateral component of hypercellularity with carcinoma (arrow) and the intermediate and medial component of hypocellularity with pleomorphic adenoma (curved arrow). H.
