【摘要】 目的：探讨ＣＴ在肝脏炎性假瘤诊断中的价值。方法：１６例经手术或病理证实的肝脏炎性假瘤均作平扫及增强扫描，１０例采用动态增强扫描，６例为螺旋ＣＴ多期扫描。结果：ＣＴ平扫表现均为低密度灶，边界不清，增强动脉期扫描病灶无强化，门脉期和延迟期扫描１３ 例可见到周边环形强化；２ 例为整个病灶轻度到中度不均匀强化；１例为病灶中心结节状强化。另外１６ 例中有９例可见到病灶内纤维分隔形成。结论：ＣＴ动态增强扫描和螺旋ＣＴ多期扫描可充分反映病灶的血供特点和病理特征，在肝脏炎性假瘤的诊断和鉴别诊断中具有很大价值。更多还原

【Abstract】 Objective:To explore the value of CT in the diagnosis of inflammatory pseudotumor of the liver.Methods:16 cases with inflammatory pseudotumor of the liver confirmed by surgery or pathology underwent pre and postcontrast CT scan.10 cases carried out by dynamic CT scan and the other 6 cases carried out by multi-phase scan of the helical CT.Results:All lesions were hypodense on the precontrast CT scan and their boundary was unclear.Noenhancement was demonstrated on the arterial phase scan in all lesions,ring-shaped enhancement located in the periphery of the lesion were found in 13 cases on the portal venous phase and delayed phase scan,2 lesions had slight or middle unhomogenous enhancement,1 lesion had central nodular enhancement.On the other hand,the foci fibrous septa were found in 9 lesions of all lesions.Conclusion:Dynamic CT scan and multi-phase scan of helical CT can reflect sufficiently the blood supply and pathological characterizations of inflammatory psendotumor of liven and are of great value in the diagnosis and differential diagnosis.更多还原
