摘要 目的探讨肝细胞腺瘤的B超、CT和MRI的影像学特点。方法回顾性总结分析12例肝细胞腺瘤的临床和影像学资料。结果B超示6例为低回声或略低回声,4例为强回声或略强回声,2例为杂乱回声。肿块内回声除1例外都不均匀,4例边界不清或欠清,8例边界清楚,CT示12例为边界清楚的低密度或稍低密度,除因出血和坏死外密度较均匀,增强后病灶动脉期明显强化,门脉期和延迟期造影剂退出呈现和正常肝组织密度。MRI上大部分病例表现为T1W1和T2W1高信号,增强后动脉期明显强化,门脉期和延迟期呈等信号。结论利用B超发现肝占位,再结合CT或MRI的动态增强扫描有助于肝细胞腺瘤的明确诊断。 Objective To describe the sonography?CT and MRI features of hepatocellular adenoma.Methods The images and clinical material of 12 patients were retrospective analysed.Result Ultrasonography show 6 lesions had hypoechogenicity or mildly hypoechogenicity,4 with hyperechogenicity or mildly hyperechogenicity or mildly hypoechogenici-ty,4 with hyperechogenicity or mildly hyperechogenicity and 2 was mixed echogenicity.The echo in the lesion was not equal but 1 patient.The margin in 8 was clear and 4 was not.On unenhanced CT scans,12 hepatic adenomas are well-circumscribed lesions that display low or slight low attenuation and homogeneous if without hemorrhage,or necrosis.On CT scans obtained after contrast injection,hepatic adenomas show early homogeneous enhancement during the arterial dominant phase.On portal venous phase and delayed CT scans,hepatic adenomas exhibit attenuation nearly identical to that of the normal liver.MRI shows most are hyperintense relative to normal liver on T1-and T2-weighted images.On dynamic enhanced gradient-echo MR images,adenomas show early arterial enhancement and become nearly isointense relative to liver on delayed images.Conclusion Ultrasonography can be used to find the liver lesion.The enhancement of CT or MRI may allow distinct from other hepatic masses.
