Although neuroblastoma is a common solid organ malignancy in children, primary pancreatic neuroblastoma is a rare entity in children, with very few cases reported in the literature. The case discusses the presentation of a 21-month-old female presenting to the neurology clinic with ataxia and erratic eye movements. Our case illustrates the computed tomography, ultrasound, and scintigraphic findings of primary pancreatic neuroblastoma presenting as opsoclonus-myoclonus syndrome. Computed tomography and ultrasound demonstrated a vascular, enhancing mass in the pancreatic body clearly separate from the adrenal gland. Metaiodobenzylguanidine scan demonstrates focal intense uptake in the pancreatic body. The patient's diagnosis was confirmed with biopsy, and her malignancy responded well to conventional chemotherapy. The case is important in that it demonstrates the unusual imaging appearance of a primary pancreatic neuroblastoma.
