摘要
目的:探讨腮腺腺淋巴瘤的临床及CT表现,以提高其诊断率。方法:回顾性分析经手术及穿刺活检病理证实的12例腮腺腺淋巴瘤的CT表现。结果:12例腮腺腺淋巴瘤中,单侧发病11例,双侧发病1例,共13侧发病;男10例(83.3%),女2例(16.7%);单发9例(75%,9/12),多发3例(25%,3/12),共16个病灶,9个(56.3%,9/16)病灶位于腮腺后下方。CT表现病灶呈圆形、椭圆形及分叶状软组织肿块,边缘清晰,密度均匀10个,坏死囊变致密度不均匀6个;增强扫描除囊变区外,病灶呈早期均匀强化,以中度强化为主,囊变区不强化。结论:根据腮腺腺淋巴瘤的发病性别、年龄、部位及影像学表现,有助于诊断和鉴别诊断。
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.
