Pancreatic neuroendocrine neoplasms occasionally have a cystic component. We herein report a case of multiple hepatic tumors, including a huge one and a 24-mm sized pancreatic cystic lesion. The hepatic tumor showed an enhancement pattern consistent with hepatic adenoma. The pancreatic cystic lesion revealed a thickened outside border and a solid inside component, which was enhanced following a contrast study, suggesting cystic pancreatic neuroendocrine neoplasm. Surgical resection was performed. After the surgery, somatostatin receptor scintigraphy detected an occult lumbar spine metastasis. Huge multiple liver and bone metastases of the neuroendocrine neoplasm G2 component were seen, with a G1 small primary lesion.
胰腺神经内分泌肿瘤偶尔会有囊性成分。我们在此报告一例多发性肝肿瘤病例，包括一个巨大肿瘤和一个24毫米大小的胰腺囊性病变。肝肿瘤的强化模式与肝腺瘤一致。胰腺囊性病变显示边界增厚且内部有实性成分，增强扫描后强化，提示为胰腺囊性神经内分泌肿瘤。进行了手术切除。术后，生长抑素受体闪烁显像检测到隐匿性腰椎转移。可见神经内分泌肿瘤G2成分的巨大多发性肝转移和骨转移，原发灶为G1小病变。
