【摘要】：目的:研究腮腺腺淋巴瘤的16层MSCT增强影像特点,结合病理基础进行评价,以提升对该类型肿瘤CT征象的认识。方法:观察34例经病理确诊的腮腺腺淋巴瘤患者的16排MSCT增强影像特征,对病变发生的部位、形态、密度、增强CT特点进行观察并分析。结果:34例腮腺腺淋巴瘤患者共86个病变。12例双侧同时发病(双侧单发2例,双侧多发10例),22例单侧发病(单侧单发12例,单侧多发10例);66个病变位于腮腺浅叶后下方。增强扫描动脉期各病变多呈中度或明显强化,病变内囊变区无强化。结论:出现在单侧或双侧腮腺浅叶后下极的结节或肿块,常见多发病变,边界清楚,增强为中度或显著强化,内部可见大小不等的囊变、液化,是腮腺腺淋巴瘤较为特异性的增强MSCT征象。
[Abstract]:Objective: to study the features of 16-layer MSCT enhanced imaging of parotid gland lymphoma and evaluate it with pathological basis. Methods: 16-row MSCT enhanced imaging features of 34 patients with pathologically diagnosed parotid gland lymphoma were observed, and the location, morphology and density of the lesions were observed. Results in 34 cases of parotid gland lymphoma, 86 lesions and 12 cases occurred simultaneously (2 cases were bilateral unilateral, 10 cases were bilateral multiple, 22 cases were unilateral, 12 cases were unilateral. Multiple lesions on one side were found in 10 cases, 66 lesions were located below the superficial lobe of parotid gland. Most of the lesions showed moderate or obvious enhancement in arterial phase, and no enhancement was found in the lesions. Conclusion: nodules or masses at the posterior lower pole of the superficial lobe of the parotid gland on either side or both sides of the parotid gland appear in the posterior lower pole of the parotid gland. The common frequently-occurring lesions with clear borders and moderate or significant enhancement with varying sizes of cysts and liquefaction are relatively specific contrast-enhanced MSCT signs for parotid gland lymphoma.
