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.
