Rhinosinusitis and intracranial hemorrhage are prevalent conditions within their respective medical specialties. While rhinosinusitis is predominantly an inflammatory disease confined to the paranasal sinuses, it can, in exceedingly rare circumstances, lead to intracranial hemorrhage with potentially fatal outcomes. Despite the gravity of this rare association, the literature remains sparse regarding its pathophysiological mechanisms, natural history, management principles, and clinical outcomes. ⋯ Intracranial hemorrhagic complications, primarily EDH and subdural hematomas, are rare and potentially fatal consequences of rhinosinusitis. It should be cognizant of the potential existence of such a possibility during clinical practice.
