Intramedullary spinal cord metastasis(ISCM) is very rare and its optimal treatment remains controversial. Pancreatic neuroendocrine tumor(pNET) is a rare tumor that usually presents with hepatic metastasis. Hepatic failure due to tumor progression is the major cause of death in cases of pNET. To date,no report has described a case of ISCM from pNET. Although spinal cord metastasis of a solid tumor is uncommon,it is a critical condition that can cause a potentially irreversible loss of neurologic function. Here,we report the case of a 45-year-old man who presented with leg weakness and voiding difficulty,and was found to have ISCM from pNET. Surgical treatment prevented further neurological deterioration. This is the first case report of ISCM from pNET.
