Focal lesions of the liver often have various imaging characteristics which may be interpreted as either benign or malignant. Understanding the underlying pathophysiology of these liver lesions may lead to characteristic imaging manifestations, which direct the radiologist to the diagnosis. Benign lesions include congenital hepatic cyst, autosomal dominant polycystic disease, hemangioma, focal nodular hyperplasia (FNH), hepatic adenoma, inflammatory pseudotumor, peliosis hepatis, focal fatty infiltration, hamartoma, and infectious processes such as hepatic abscess, echinococcal cyst, and candidiasis. Characteristic imaging features, clinical symptoms, and treatment/prognosis will be discussed. Emphasis will be placed on key reliable features of each disease to develop a method of discriminating these lesions from other benign and malignant disorders.
肝脏局灶性病变通常具有多种影像学特征，这些特征可能被解释为良性或恶性。了解这些肝脏病变的潜在病理生理学可能会导致特征性的影像学表现，从而指导放射科医生进行诊断。良性病变包括先天性肝囊肿、常染色体显性多囊肾病、肝血管瘤、局灶性结节性增生（FNH）、肝腺瘤、炎性假瘤、肝紫癜、局灶性脂肪浸润、错构瘤以及诸如肝脓肿、棘球蚴囊肿和念珠菌病等感染性病变。将讨论其特征性影像学表现、临床症状以及治疗/预后。重点将放在每种疾病的关键可靠特征上，以建立一种将这些病变与其他良性和恶性疾病区分开来的方法。
