肝腺瘤的CT及MRI表现及误诊分析

目的回顾性分析肝腺瘤的CT、MRI表现及其鉴别诊断,并结合文献复习对其误诊原因进行探讨。方法回顾性分析8例经病理证实为肝腺瘤患者的CT及MRI资料。CT扫描包括平扫及三期（动脉、门脉、延迟）增强扫描;MR检查为常规扫描,其中2例另外接受氢质子磁共振波谱（^1H-MRS）检查。结果8例肝腺瘤患者中,4例表现较为典型,均做出正确诊断;4例表现不典型,其中3例误诊为肝癌,1例误诊为肝局灶性结节增生（FNH）。2例肝腺瘤的^1H-MRS可见肿瘤组织与瘤周正常肝组织胆碱峰的差异不明显。结论肝腺瘤的CT及MRI表现具有一定的特征,但表现不典型时易误诊。^1H-MRS对肝腺瘤可能具有鉴别诊断价值。

CT and MRI appearances and the causes of misdiagnosis of hepatic adenoma

Objective To retrospectively analyze CT and MR appearances of hepatic adenoma,and to study the causes of misdiagnosis with review of relative literatures.Methods CT and MRI data of 8 patients with pathologically confirmed hepatic adenoma were retrospectively analyzed.Pre-and post-contrast tri-phase(arterial,portal venous and delayed) CT scans and routine MR scan were performed in all 8 patients,and proton magnetic resonance spectroscopy(1H-MRS) was performed in 2 patients.Results Typical demonstrations were...
