青海大学附属医院于2023年8月收治一例53岁男性患者。患者自述平时无特殊不适，无肩背部放射痛和腹部疼痛等症状，无牛羊犬等动物密切接触史或长期流行区生活史。入院后查体和实验室检查均无异常。结合患者病史及腹腔脏器三期动态增强CT等影像学检查，初步诊断为胰腺浆液性囊腺瘤。在排除相关手术禁忌症后行腹腔镜下胰体尾切除术，术中发现腹腔内无腹水，肿块位于胰腺体部，边界不清，突出于胰腺表面，大小约4.0 cm × 3.7 cm × 3.0 cm，活动度较差，并与周围肠管黏连。肝脏质地和色泽正常。完整切除胰腺体尾部及病灶后，术中冰冻病理提示为胰体部细粒棘球蚴病。患者术后生命体征平稳，恢复顺利。1个月后复查上腹部CT平扫显示术区较前好转，患者自述术后恢复良好，无明显特殊不适，饮食和睡眠正常，大小便正常，余未见明显异常。

The Affiliated Hospital of Qinghai University admitted a 53-year-old male patient in August 2023, who reported that he usually had no special discomfort, no symptoms such as radiating pain in the shoulder and back and abdominal pain, and no history of close contact with animals such as cattle, sheep, and dogs or living in a long-term endemic area. Physical examination and laboratory tests after admission were not abnormal. Combined with the patient’s medical history and imaging examinations such as three-phase dynamic-enhanced CT of the abdominal organs, the preliminary diagnosis was pancreatic plasma cystadenoma. After excluding relevant contraindications to surgery, laparoscopic pancreatic body-tail resection was performed. Intraoperatively, it was found that there was no ascites in the abdominal cavity, and the mass was located in the body of the pancreas, with unclear borders, protruding from the surface of the pancreas, measuring about 4.0 cm × 3.7 cm × 3.0 cm, with poor mobility and adhesion to the surrounding intestinal tract. The liver was normal in texture and color. After complete resection of the caudal part of the pancreatic body and the lesion, intraoperative frozen pathology suggested cystic echinococcosis of the pancreatic body. The patient’s postoperative vital signs were stable and recovery was uneventful. One month later, a follow-up CT scan of the upper abdomen showed that the operated area was better than before, and the patient reported that he had recovered well after the operation, with no obvious special discomfort, normal diet and sleep, normal urination and defecation, and the rest of the patient did not see any obvious abnormality.
