肝脏部位生长的肿瘤可分为良性肿瘤和恶性肿瘤两大类。肝脏的良性肿瘤以肝海绵状血管瘤最为常见。肝腺瘤较少见 ,肝错构瘤、肝畸胎瘤等极少见。由于Ｂ型超声检查在临床上已经普遍使用 ,因此发现肝脏囊肿的较为常见。这类肿瘤的发生大多与先天发育异常有关 ,所以病人年龄较轻。 The growth of liver tumor can be divided into two major categories of benign and malignant tumors. Liver benign tumors with hepatic cavernous hemangioma the most common. Hepatic adenoma is rare, hepatic hamartoma, liver teratoma and other rare. Because B-mode ultrasonography has been widely used clinically, it is more common to find liver cysts. Most of these tumors are associated with congenital dysplasia, so patients are younger.
