摘要
目的：分析上皮型、混合型肝母细胞瘤（HB）的不同影像学表现及其病理基础，并比较CT、彩色多普勒超声对上皮型、混合型小儿HB的诊断价值。方法：对45例经病理证实的小儿HB的CT和彩色多普勒超声图像进行回顾性分析，比较两者对上皮型和混合型HB诊断的准确性。结果：上皮型HB内钙化少见，混合型HB内钙化多见，两者之间的差别有统计学意义（χ2=13.6，P<0.05）；上皮型HB在超声图像上多为高回声影，混合型HB在超声图像上多为液性低回声，两者之间的差别有统计学意义（χ2=12.00，P<0.05）。结论：上皮型和混合型HB影像学表现具有特异性，CT和彩色多普勒超声均能较准确的诊断上皮型和混合型HB。CT对HB及其分型诊断的准确性较高，但彩色多普勒超声对患者的损害较小，可以作为初筛的手段。
Abstract
Objective: To analyze the different imaging findings of epithelial hepatoblastoma(HB) and mixed HB, and to assess the value of CT and color Doppler ultrasonography in the diagnosis of epithelial HB and mixed HB in infants. Methods: CT and color Doppler ultrasonography findings of epithelial HB and mixed HB were evaluated retrospectively in 45 patients with histological confirmation. Accuracies of CT and color Doppler ultrasonography of them were compared. Results: Epithelial HB contained less calcification. And more calcification was discovered in mixed HB. There was significant difference in ratio of calcification in epithelial HB and mixed HB(χ2=13.6, P<0.05). Color Doppler ultrasonography showed high-level echo inside mixed HB lesions. And low-level echo signal was showed in epithelial HB lesions. There was significant difference in intensity of epithelial HB and mixed HB(χ2=12.00, P<0.05). Conclusion: Epithelial HB and mixed HB have characteristics on CT and ultrasound images.
