肝细胞腺瘤6例临床与影像资料分析

HEPATOCELLULAR ADENOMA:CLINICAL AND PATHOLOGICAL FEATURES IN 6 PATIENTS

为研究肝细胞腺瘤的临床病理特征 ,作者回顾性分析了经手术切除 6例肝细胞腺瘤病史、影像资料、病理改变及手术体会。 6例肝细胞腺瘤均为单发 ,男性 4例 ,女性 2例 ,肿瘤直径 4～ 11cm(平均 8.5cm) ,肿瘤血供丰富 ,易发生坏死、出血和脂肪变。肿瘤无出血、坏死及脂肪变区域在平扫、门脉期、延迟期其密度与正常肝组织相近 ,T1加权像 6例肿瘤均表现为以高信号为主的混杂信号 ;肿瘤均得到完整切除 ,无严重并发症及手术死亡。肝细胞腺瘤的CT、MRI影像表现具有一定的特征 ,结合肝细胞腺瘤多变的病理特征考虑有助于提高诊断。

To study the clinical and pathological features of hepatocellular adenomas.History and comprehensive imaging features in 6 patients with confirmed hepatocellular adenomas were reviewed retrospectively and correlated with pathological findings.The results showed that all six patients had solitary adenomas. Of the 6 patients, 4 were men and 2 were women. The diameter of tumors ranged from 4 to 11 centimeters, with an average of 8.5 centimeters. All the adenomas were hypervascular, and were nearly isoattenuating to normal liver on nonenhanced, portal vein period and delayed images except for areas of necrosis, hemorrhage, or focal fatty degeneration. Six lesions showed heterogeneously high signal intensity on T1 weighted images of MRI. All tumors were resected completely, and there were no serious complications and death. It suggested that these tumors may have some common features on CT and MRI images that should allow us to improve our diagnostic ability, if we could contrast imaging features with pathological characters. The surgical operation is effective.
