目的 提高对肝母细胞瘤CT各种形态的认识 ,评价CT检查的作用。方法 2 4例均经CT腹部平扫 ,1 2例加作增强扫描。对照手术病理结果 ,结合文献回顾性分析肝母细胞瘤CT所见。结果 肿物位于右肝 1 4例、左肝 4例、左及右肝者 6例 ,其中 1例较弥漫。肝母细胞瘤大多表现为肝内单个球形或分叶状融合的实性肿块 ,3例为多发结节。 7例肿物呈外生型 ,2 1例边界清 ,3例包膜完整。肿物密度多不均匀 ,增强后可不均等或呈弧线形、网格状强化 ,CT值上升 1 8～ 70HU。 6例肿瘤有钙化。全部病例肿瘤以外肝实质正常 ,2例CT定位与手术不一致。 2例大网膜和膈面转移 (其中1例肿瘤膈面破裂 )CT未能分辨。 1例下腔静脉瘤栓。淋巴结转移少见 (1例 )。结论 CT扫描对肿瘤定位定性较准确 ,对肿瘤分期有一定限度
Objective To improve the understanding of various forms of CT in hepatoblastoma and evaluate the effect of CT. Methods Twenty - four cases were all scanned by CT abdomen and 12 cases were treated with enhanced scanning. According to the pathological results of the surgery, combined with the literature retrospective analysis of hepatoblastoma seen CT. Results The tumor was located in 14 cases of right liver, 4 cases of left liver, 6 cases of left and right liver, of which 1 case was more diffuse. Hepoblastoma mostly presents as a solid mass with single spherical or lobulated fusion in the liver, with multiple nodules in 3 cases. Seven cases of tumor was exogenous, 21 cases of border clearance, 3 cases of complete capsule. Inhomogeneous tumor density, enhanced after the uneven or arc-shaped, grid-like enhancement, CT value increased 18 ~ 70HU. Six patients had calcification. All cases of normal liver tumor outside the tumor, 2 cases of CT location and operation is inconsistent. 2 cases of omentum and diaphragmatic metastasis (including 1 case of tumor diaphragmatic rupture) CT failed to distinguish. One case of inferior vena cava tumor thrombus. Lymph node metastases are rare (1 case). Conclusion The CT scan is more accurate in the localization of the tumor and has a certain limit to the tumor staging
