Sudden death due to undiagnosed central nervous system tumors is an uncommon, but well-described occurrence. Most of the tumors in these circumstances are supratentorial and occur in a wide spectrum of ages. Brainstem tumors are more rare and occur predominantly in the pediatric and adolescent populations. We present the case of a 48-year-old man who died suddenly and unexpectedly of a brainstem glioma. This case is unusual because of his age and the paucity of antecedent symptoms.
