摘要
目的:提高对肝脓肿螺旋CT平扫及三期增强扫描征象的认识,减少临床误诊。方法:20例经临床确诊患者,全部行螺旋CT平扫及三期增强扫描,分析其CT表现。结果:单发病灶15例,多发病灶5例。位于肝右叶12例,位于肝左叶5例,肝左右叶同时累及3例。典型肝脓肿表现为中央均匀液化坏死区、边缘有"双靶征"、病灶内有积气等CT表现。结论:螺旋CT三期增强扫描的特征性表现,对肝脓肿的诊断及鉴别诊断具有重要价值。
Objective:To improve the knowledge about spiral CT scan and three periods of enhanced scan signs of liver abscess and reduce the clinical misdiagnosis.Methods:20 cases of patients with clinically diagnostic all accepted spiral CT scan and three periods of enhanced scan,analyzing the CT manifestations.Results:15 cases had single lesion,5 cases had multiple lesions.12 cases were located in the right liver lobe,5 cases were located in the left hepatic lobe,3 cases had the involvement of hepatic lobe at the same time.The typical liver abscess were characterized by CT performance such as uniform central liquefied necrotic area,’double target sign’in edge,lesions with pneumatosis.Conclusion:The characteristic scan of three phases enhanced spiral CT had important value for the diagnosis and differential diagnosis of liver abscess.
