儿童肝脏肿瘤的影像学诊断

Imaging diagnosis of liver tumors in children

原发性儿童肝脏肿瘤并不罕见,儿童肝脏恶性肿瘤发生率位居儿童腹部恶性肿瘤第3位,具有恶性率高,先天性肿瘤多见和好发年龄明显的特点。而且儿童肝脏肿瘤无特异性临床表现,发病隐匿、肿瘤病灶体积大、病理类型多、发生部位复杂,与成人相比处理更为困难。对小儿肝脏肿瘤的影像诊断进行了综合阐述,指出随着影像医学的迅猛发展,影像学检查在明确肝脏肿瘤的发生部位、提示肿瘤良恶性及肿瘤分级方面具有越来越重要的参考价值。

Primary liver tumors in children are not rare,and the incidence of malignant liver tumors in children ranks third of all malignant abdominal tumors in children,with the features of a high rate of malignancy,a high incidence of congenital tumors,and a specific age of onset.Liver tumors in children often have no specific clinical manifestations,with an insidious onset,a large volume of tumor lesion,various pathological types,and complicated locations,which makes them more difficult to treat compared with liver tumors in adults. This article reviews the imaging diagnosis of liver tumors in children and points out that with the rapid development of imaging medicine,imaging examination provides an important reference for clarifying the location of liver tumors,identifying benign or malignant tumors,and determining tumor stage.
