Hepatoblastoma is the third most common intraabdominal malignant neoplasm in infants. Computed tomography of six patients with surgically proven hepatoblastoma was reviewed; abnormalities included large, diffuse, or multifocal liver masses with lower attenuation values than normal hepatic parenchyma after contrast enhancement. In three patients, areas of speckled or amorphous calcifications within the tumor were evident on CT, whereas calcification was present on conventional radiography in only one patient. In four of the six infants, CT demonstrated unresectable tumor by virtue of massive pansegmental involvement. Computed tomography is a useful tool for screening patients with suspected hepatoblastoma and for determining the anatomic extent of tumor and thus selecting a group of children for aggressive surgical excision.
肝母细胞瘤是婴儿期第三常见的腹腔内恶性肿瘤。回顾了6例经手术证实为肝母细胞瘤患者的计算机断层扫描结果；异常表现包括肝脏出现大的、弥漫性或多灶性肿块，增强扫描后其衰减值低于正常肝实质。3例患者的肿瘤内可见斑点状或无定形钙化区域，而传统X线摄影仅1例患者有钙化表现。6例婴儿中有4例，CT显示肿瘤因广泛累及全肝叶而无法切除。计算机断层扫描是筛查疑似肝母细胞瘤患者、确定肿瘤解剖范围从而选择一组适合积极手术切除的儿童的有用工具。
