肝脏炎性假瘤的CT表现及鉴别诊断

CT Features and Differential Diagnosis of Inflammatory Pseudotumor of the Liver

目的:探讨肝脏炎性假瘤的CT表现和诊断价值。材料和方法:回顾性分析经病理证实的肝脏炎性假瘤19例之CT表现。结果:17例单发病灶,2例多发病灶。19个病灶呈低密度,2个病灶呈等密度;增强扫描动脉期无明显增强,门脉期、延迟期病灶为边缘增强、间隔增强及中心或壁结节增强。结论:大部分炎性假瘤CT三期动态扫描能够正确诊断。

Purpose： To analyze the CT appearances and diagnostic value of inflammatory pseudotumor of the liver （IPL）. Materials and Methods： The CT findings of 19 patients with inflammatory pseudotumor of the liver proved by pathology were analyzed respectively. Results： 17 cases were solitary lesion and 2 cases had multiple lesions. 19 lesions showed hypode;ase, 2 lesions isodense on pre-contrast. On the contrast CT scan, showed no enhancement during arterial phase, but during portal venous phrase and delayed phase, strong enhancement at the edge and sepia in the center or mural node, of the lesions were visible. Conclusion： CT diagnosis is possible in most cases of IPL by three phase dynamic scanning.
