Pancreatic neuroendocrine tumours (PanNETs, PETs, or PNETs), often referred to as "islet cell tumours", [1] [2] or "pancreatic endocrine tumours" [3] [4] are neuroendocrine neoplasms that arise from cells of the endocrine and nervous system within the pancreas.

Children are much more prone to exhibit these dysembryoplastic neuroepithelial tumours than adults. [1] The mean age of onset of seizures for children with DNTs is 8.1 years old. [ 1 ] Few other neurological deficits are associated with DNTs, so that earlier detection of the tumour before seizure symptoms are rare. [ 2 ]
