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。
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.
