儿童肝脏肿瘤的CT、MRI诊断及临床分析

目的：探讨儿童肝脏肿瘤的CT、MRI诊断价值及临床表现特征。方法：回顾性分析13例经手术及穿刺病理证实的儿童肝脏肿瘤，男11例，女2例，年龄最小13个月，最大14岁，平均10．8岁。10例行CT扫描，6例行MRI扫描。结果：13例中，原发性肝癌7例（78％），肝母细胞瘤3例（23％），白血病肝脏侵润1例，肝血管瘤1例，肝间叶性错构瘤1例，不同病理类型肿瘤有其各自影像学特点。结论：CT与MRI检查可准确显示恶性肝肿瘤的部位、大小、侵润范围、影像特点及转移情况，为肿瘤的临床分期、制定治疗方案、估计预后提供重要依据。

CT/MRI Diagnosis and Clinical Manifestations of Liver Tumors in Child

Objective To investigate the CT and MRI value in diagnosis and clinical manifestations of liver tumor in child. Methods 13 cases of surgically and pathologically confirmed liver tumor were retrospectively analyzed that 11 males, 2 females, age range from 13 months to 14 years, average age 10.8 years. Contrast CT was undertaken in 10 patients and MRI in 6 patients. Results In all cases comprised primary hcpatocellular carcinoma 7 cases（8%）, hepatoblastoma 3 cases（23%）, leukemia involved liver 1 case, cavernous hemangioma 1 case, hepatic mesenchymal hamartoma 1 case. Different type of tumor had its own imaging manifestations. Conclusion CT and MRI can precisely delineate the location, size, extent of involvement. It provides an important basis of clinical staging for tumors prognosis and treatment.
