摘要: 目的 回顾总结肝细胞腺瘤(HCA)影像学特征,为临床诊治提供经验。方法 2020年5月~2024年3月我院收治的39例HCA患者,接受腹部CT和MR检查,取组织行免疫组化和基因表型检测。结果 本组包括炎症型HCA(I-HCA)18例,β-链蛋白突变激活型(B-HCA)10例,肝细胞核因子1α突变失活型(H-HCA)6例和未分类型(U-HCA)5例;I-HCA病灶CT增强扫描延迟期低强化占55.6%,显著高于H-HCA的10.0%(P<0.05)或H-HCA的0.0%(P<0.05)或U-HCA的0.0%(P<0.05);B-HCA病灶包膜下增强血管影占比为100.0%(P<0.05),显著高于I-HCA的38.9%(P<0.05)或H-HCA的10.0%(P<0.05)或U-HCA的20.0%(P<0.05);I-HCA病灶MR T1WI序列高信号占比为72.2%,显著高于H-HCA的10.0%(P<0.05)或B-HCA的16.7%(P<0.05)或U-HCA的0.0%(P<0.05);H-HCA病灶T2WI序列以低信号为主,表现为轻度增强,强化逐步减退,均与其他分型存在显著性差异(P<0.05)。结论 HCA以I-HCA多见,不同分子分型HCA病灶CT和MRI征象略有差异,需在今后的研究中进一步总结完善。

Abstract: Objective The aim of this study was to summarize imaging features of hepatocellular adenoma (HCA). Methods The clinical materials of 39 patients with HCA encountered in our hospital between May 2020 and March 2024 were reviewed. All patients underwent CT and MR scan. Histo-pathological typing was performed by immunohistochemistry and genotype sequencing. Results Of 39 patients with HCA in our series, inflammatory HCA (I-HCA), β-catenin-activated HCA (B-HCA), hepatocyte nuclear factor 1α-inactivated HCA (H-HCA) and unclassifled HCA (U-HCA) were found in 18 cases, 10 cases, 6 cases and 5 cases, respectively; percentage of low enhancement at delayed phase in I-HCA lesions was 55.6%, much higher than 10.0%(P<0.05) in H-HCA or 0.0%(P<0.05)in H-HCA or 0.0%(P<0.05)in U-HCA lesions; percentage of subcapsular enhancement in B-HCA lesions was 100.0%(P<0.05), much higher than 38.9%(P<0.05) in I-HCA or 10.0%(P<0.05)in H-HCA or 20.0%(P<0.05)in U-HCA; percentage of high signal at MR T1WI sequence in I-HCA was 72.2%, much higher than 10.0%(P<0.05) in H-HCA or 16.7%(P<0.05) in B-HCA or 0.0%(P<0.05)in U-HCA lesions; low signal intensity at T2WI sequence in H-HCA was more common, with a slight enhancement, gradually decreased, significantly different from other HCA types(P<0.05). Conclusion I-HCA is more common clinically, with a slight different imaging feature in different HCA types, which needs further summarization.
