肝血吸虫病误诊肝癌CT与病理对照分析
The Matched Control Analysis of Misdiagnosis Hepatic Schistosomiasis to Hepatocarcinoma by CT and Pathology
-
摘要: 目的 分析肝血吸虫病误诊为肝癌病例的基本CT特点, 探讨避免误诊的途径。方法 2 2例CT初诊为肝癌, 经皮肝脏穿活检或手术证实为肝血吸虫病的患者, 对肝血吸虫病的常见CT征象进行综合分析, 并与病理结果相对照, 探讨不典型的肝血吸虫病的CT特点。结果 2 2例患者均出现肝叶比例失调和肝内结节病灶, 并且 90 .91%的患者具有结节强化和肝裂增大的特点。 16例脾脏增大, 2 1例汇管区有低密度灶。增强扫描强化以静脉期为主, 且表现为边缘轻度环行强化, 动脉期未见结节内供血动脉影, 延迟期强化不明显。结论 不典型的肝血吸虫病, 肝硬化征象和静脉期边缘轻度环行强化可能有一定的参考价值, 经皮肝脏穿刺找到虫卵结节是最为经济有效的方法Abstract: Objective To study the characteristics of liver schistosomiasis misdiagnosis hepatocarcinoma by spiral CT and research the methods to avoid misdiagnosis. Methods Twenty-two patients were diagnosis as “hepatocarcinoma” by spiral CT, but other radiology examinations did not agree with it. All the patients were performing partial hepatectomy or needle biopsy of liver. After the operations, we found there were not hepatocarcinoma but liver schistosomiasis by pathology. We analysis all the valuable CT signature...
