Abdominal ultrasonography in a 70-year-old woman showed a hypoechoic mass, 14 mm in diameter, in the pancreatic body. Computed tomography showed a mass with contrast effect in the pancreatic body. Test results for endocrine factors or tumor markers were normal. The initial consideration was nonfunctional pancreatic neuroendocrine tumor. Over 8 years of monitoring, the tumor diameter increased to 18 mm, until pancreatic tumor enucleation was performed. The postoperative diagnosis was pancreatic hamartoma, a rare type of benign pancreatic tumor. The preoperative diagnosis of pancreatic hamartoma is difficult, but consideration must be given to the possibility of hamartoma when encountering pancreatic tumors.
一名70岁女性的腹部超声检查显示胰体部有一个直径14毫米的低回声肿块。计算机断层扫描显示胰体部有一个有造影剂增强效应的肿块。内分泌因子或肿瘤标志物的检测结果正常。初步考虑为无功能性胰腺神经内分泌肿瘤。经过8年多的监测，肿瘤直径增至18毫米，直至进行了胰腺肿瘤剜除术。术后诊断为胰腺错构瘤，这是一种罕见的胰腺良性肿瘤。胰腺错构瘤的术前诊断困难，但遇到胰腺肿瘤时必须考虑错构瘤的可能性。
