Focal nodular hyperplasia is a common benign tumour of the liver that usually does not require treatment. This tumour can be difficult to distinguish noninvasively from other lesions in young patients that may require intervention, such as hepatic adenoma and fibrolamellar carcinoma. The authors report three cases of histologically proven focal nodular hyperplasia and one case in which the imaging features strongly suggested this tumour. These cases illustrate many of the variable imaging features of focal nodular hyperplasia. The authors review the typical imaging findings for focal nodular hyperplasia, hepatic adenoma and fibrolamellar carcinoma, indicate the areas of overlap that make noninvasive diagnosis impossible and discuss the role of percutaneous biopsy in establishing the definitive diagnosis.
局灶性结节性增生是一种常见的肝脏良性肿瘤,通常无需治疗。在年轻患者中,这种肿瘤很难通过非侵入性手段与其他可能需要干预的病变区分开来,如肝腺瘤和纤维板层癌。作者报告了三例经组织学证实的局灶性结节性增生病例以及一例影像学特征强烈提示为该肿瘤的病例。这些病例说明了局灶性结节性增生许多多变的影像学特征。作者回顾了局灶性结节性增生、肝腺瘤和纤维板层癌的典型影像学表现,指出了导致无法进行非侵入性诊断的重叠区域,并讨论了经皮活检在确立明确诊断中的作用。
