We describe the case of a 40s woman with a carbohydrate antigen (CA)19-9-producing splenic cyst. The lesion was detected incidentally at the splenic hilum, and resected after 5 years of follow-up. Size of the lesion was enlarged from 1.6 cm to 5.3 cm, and serum CA19-9 was elevated from the normal range to 1766 U/ml. Microscopically, CA19-9-producing splenic cyst was diagnosed. It was mimicked pancreatic malignancy due to its location at the splenic hilum. Benign lesions with elevated serum CA19-9 also to be differential diagnosis.

我们描述了一例40多岁患有产生碳水化合物抗原（CA）19-9的脾囊肿的女性病例。该病变在脾门处偶然发现，经过5年随访后进行了切除。病变大小从1.6厘米增大至5.3厘米，血清CA19-9从正常范围升高至1766 U/ml。显微镜检查确诊为产生CA19-9的脾囊肿。由于其位于脾门处，曾被误诊为胰腺恶性肿瘤。血清CA19-9升高的良性病变也需进行鉴别诊断。
