A normal daily routine turns critical in seconds, and a biophysical maneuver that is instinctual leads to a rapid decline in a young healthy patient without any warning or precipitating signs. The Valsalva maneuver is a commonly used term for the act of bearing down that affects the vagus nerve, resulting in systemic changes primarily within the autonomic nervous system. This paper reviews a case in which a young man engaging in the Valsalva maneuver was later found unconscious and presented to the emergency department. Neuroimaging revealed a large middle cerebral artery stroke along with an undiagnosed temporal arachnoid cyst, without any significant historical medical records. The resulting course of this disease remained an interesting area of inquiry. This case highlights a rare but intricate interplay of several major physiological functions that collectively contribute to the unexpected demise of a young and healthy patient.
