Mesenchymal hamartoma is a benign, cystic lesion that arises from connective tissues of the portal tracts. It is most common in children under 5 years of age. The diagnosis can be suspected when a relatively asymptomatic child has a large, smooth mass in the liver. Radionuclide scans demonstrate a solitary lesion, and on ultrasound there are cystic spaces and septa. These are perfectly benign lesions and may be simply enucleated.
间叶性错构瘤是一种良性囊性病变，起源于门管区的结缔组织。它在5岁以下儿童中最为常见。当一个相对无症状的儿童肝脏出现一个大的、光滑的肿块时，可怀疑有该诊断。放射性核素扫描显示为单个病变，超声检查可见囊性间隙和间隔。这些是完全良性的病变，可简单地进行剜除术。
