摘要
目的:探讨肾上腺血管平滑肌脂肪瘤的影像学表现和诊断方法。方法:对一例肾上腺血管平滑肌脂肪瘤的患者的影像和随诊资料进行分析,并对相关文献进行分析。结果:本例患者有高血压病史,超声检查二维声像图表现为左侧肾上腺区实性等回声肿块,边界清晰,形态规则。彩色多普勒显像(CDFl)示肿瘤周边及内部未见明显血流信号。CT表现为圆形软组织肿块影,增强后明显不均匀强化。镜下组织是由扭曲的薄壁血管、平滑肌及脂肪组织,免疫组化显示成熟的脂肪细胞S-100及梭形、上皮样平滑肌细胞HMB45灶性阳性,Ki-67低表达。结论:肾上腺血管平滑肌脂肪瘤虽然是少见的良性间叶组织肿瘤,但影像学能够早期发现肾上腺病灶,结合病理表现是诊断的关键。
Objective：To investigate the radiological imaging features of adrenal angiomyolipoma and to improve the diagnostic accuracy.Methods： Imaging studies and diagnostic findings of one case with adrenal angiomyolipoma and correlative records were confirmed adrenal angiomyolipoma.Results： The subject had high blood history.Ultrasound demonstrated a mass with sharp boundary and even interior homogeny.CDFI showed the mass with no obvious blood flow signal.CT scan revealled a soft tissue mass with disparity enhancement.Histopathological examination reveraled mature fat cells,smooth muscle fibers and thin-walled blood vessels suggestive of angiomyolipoma of adrenal.Immunohistochemically the case for S-100 of the adipose cells and HMB45 of the smooth muscle cells were partly positive.Conclusion： adrenal angiomyolipoma is a rare type of mesenchymal tumor.However,imaging studies correlated with pathological features are the key to diagnosis.
