- W3028624552 abstract "Objective To study the imaging characters and pathological diagnosis for space occupying lesions of the liver with atypical clinical and laboratory features.Methods We retrospectively analyzed the clinical data and treatment of 40 patients with space occupying lesions of the liver in which preoperative correct diagnosis was difficult,the imageological appearances and the final pathological diagnosis of these 40 space occupying lesions were compared,the specificity of B-ultrasonotomography、dynamic contrast-enhanced CT and MR scanning in identifying lesions was evaluated.Results All lesions were surgically resected.On pathology there were 22 hepatocellular carcinomas,7 macroregenerative nodules,2 focal nodular hyperplasias,2 cholangiocellular carcinomas,2 hemangiomas,2 regenerative nodules and 1 hepatocellular adenoma,1 hepatic peliosis,1 antixenic nodule.The specificity of the Bultrasonotomography for all lesions was only 20%;dynamic contrast-enhanced CT has low specificity in differential diagnosis of liver carcinoma and macroregenerative nodule and the overall specificity was 42.5%;dynamic contrast-enhanced MR scanning has excellent capability in differential diagnosing of all lesions and its specificity was 92.5%.Conclusion The preoperative diagnosis for some space occupying lesions of the liver is difficult,the differential diagnosis of these lesions should be emphasized,the dynamic contrastenhanced MR scanning for space occupying lesions of the liver has high specificity.Key words: Liver neoplasms; Diagnosis,differential; Dynamic contrast-enhanced MR" @default.
