Objective: The aim of the study was to investigate CT and MRI findings of parotid Warthins tumors (parotid ad-enolymphomas). Methods: CT and MRI findings of 14 patients with pathologically-confirmed Warthins tumor (10 males and 4 females) were retrospectively analyzed. The average age was 56 years (range 44-77 years). Twelve patients underwent CT plain scan, of which, 10 received the further enhancement; other 2 patients performed MR plain scan, of which, 1 was enhanced. The disease course ranged from 20 days to 4 years with the average of 22 months. Ten patients had the smoking history (71.4%). Results: A total of 22 foci were found in all 14 patients, multiple in one parotid gland in 3 patients, single in one parotid gland in 9 patients and single in bilateral glands in 2 patients (one recurred the tumor in the contralateral gland 14 years after the surgery). Sixteen (72.7%) foci or the main bodies [long diameter of 0.8-5.0 cm with the average of (2.3 ± 1.3) cm] were located in the posterior and interior role of the superficial lobe of the parotid gland. The foci were round or oval. The boundary was smooth in 21 (95.5%) foci and blurred in 3 foci which were proved by biopsy to be accompanied with infection. Fourteen foci (77.7%) with uniform density and 4 foci with nonuniform density were found in 12 patients under CT plain. A total of 15 foci in 10 patients were enhanced, 7 (46.7%) on significant enhancement, 5 (33.3%) on moderate enhancement and 3 on slight enhancement. The margin was enhanced slightly in 3 foci. In MR images, the signal of tumor was uniform or nonunifrom, T1WI showed low signal and T2WI showed moderate or high signal. The envelope displayed signal shadow under plain scan and the enhancement was slightly. Conclusion: For middle or elder males with the smoking history, if they have the foci in the posterior and interior parts of the parotid gland which show clear boundary and significant enhancement, especially for multiple or bilateral foci, parotid Warthins tumor should be considered firstly.
