Abstract：Objective: To discuss the CT and clinical appearance of adenolymphomas in the parotid gland. Methods: The CT appearances of adenolymphomas(n=12) in the parotid gland confirmed pathologically after operateration or biopsy were analysed retrospectively. Results: In 12 cases adenolymphomas of the parotid gland, 11 cases were found in unilateral side and bilateral side in 1, altogether 13 sides; male (n=10, 83.3％), female(n=2, 16.7％). Solitary lesion was seen in 9 cases (75％) and multiple lesions in 3(25％), altogether 16 lesions, 9 lesions were located in the posterior-inferior part of the parotid gland(n=9, 56.3%). CT findings: lesions were round,oval or lobulated soft tissue mass with well-defined, homogeneous density(n=10), and inhomogeneous density(n=6) with necrosis or cystic formation. Lesions showed homogeneous enhancement except the area of cystic changes, mostly with moderate enhancement. Conclusion: Fully analysing sex, age, localization of lesions and appearances of CT is useful in diagnosis and differential diagnosis.
