脾脏作为一种免疫器官,其血运丰富,肿瘤的发生率较低。脾脏硬化性血管瘤样结节性转化(sclerosing angiomatoid nodular transformation,SANT)是一种独特的良性增生性血管病变[1],在临床上较罕见。2004年,Martel等[2]首次描述了SANT的组织病理学特点并将其作为一种独立的疾病命名。笔者报道了2例脾脏SANT患者18F-FDG PET/CT显像的特点,并通过文献复习加深了对该病的认识,以充分认识SANT的诊断标准和影像学表现并进行准确诊断。

摘要: 脾脏硬化性血管瘤样结节性转化(SANT)是一种罕见的良性增生性血管病变,组织病理学检查为其诊断的“金标准”。笔者报道了2例行18F-氟脱氧葡萄糖(FDG) PET/CT显像的脾脏SANT病例,从临床、组织病理学、治疗、18F-FDG PET/CT显像等方面分析了该病的特点,并通过文献复习加深了对该病的认识,以充分认识SANT的诊断标准和影像学表现并进行准确诊断。Abstract: Sclerosing angiomatoid nodular transformation (SANT) of spleen is a rare benign proliferative vascular lesion, histopathology is the "gold standard" for diagnosis. The author reported two cases of splenic SANT with 18F-fluorodeoxyglucose (FDG) PET/CT imaging, and analyzed the clinical, histopathological, therapeutic, and 18F-FDG PET/CT imaging aspects of the disease and deepened the understanding of this disease through literature review. A full understanding of the diagnostic criteria and imaging manifestations of SANT can help to obtain more information and make an accurate diagnosis.
