Sclerosing angiomatoid nodular transformation (SANT) is a rare case which usually occurs in spleen, but our case occurs in accessory spleen.
We reported a case of a 27 year old man who was identified with an isodense mass in the left abdominal cavity by ultrasonicphysical examination without symptoms. Blood routine and tumor markers (alpha fetal protein, carcinoembryonic antigen, CA19-9, CA125) were normal.
The tumor was firstly diagnosed as left abdominal mass and its origin was considered as small intestinal by the radiologist. The pathological diagnosis was the sclerosing angiomatoid nodular transformation (SANT) of the accessory spleen.
Laparoscopic splenectomy is a more reliable method for the treatment of SANT.
Non-enhanced CT showed iso-intensity lesion of the accessory spleen, and enhanced CT showed progressive enhancement. According to the above characteristics, we should consider the diagnosis of spleen SANT. We reviewed some literatures to summarize the characteristics of SANT.
硬化性血管瘤样结节性转化（SANT）是一种罕见病例，通常发生于脾脏，但我们的病例发生在副脾。
我们报告了一例27岁男性病例，其经超声体格检查发现左腹腔有一等密度肿块，无症状。血常规及肿瘤标志物（甲胎蛋白、癌胚抗原、CA19-9、CA125）均正常。
该肿瘤最初被诊断为左腹腔肿块，放射科医生认为其起源于小肠。病理诊断为副脾的硬化性血管瘤样结节性转化（SANT）。
腹腔镜脾切除术是治疗SANT更可靠的方法。
平扫CT显示副脾等密度病灶，增强CT显示渐进性强化。根据上述特征，应考虑脾脏SANT的诊断。我们查阅了一些文献以总结SANT的特征。
