Cough Headache Presenting with Reversible Cerebral Vasoconstriction Syndrome.

Cough headache can be a primary benign condition or secondary to underlying etiologies. We herein describe a case of a 52-year-old woman with cough headache that presented as reversible cerebral vasoconstriction syndrome (RCVS). Some cases of RCVS are caused by an aberrant sympathetic response to activities that cause an intracranial pressure surge. Therefore, cough headache should be recognized as a possible presentation of RCVS, even without thunderclap headache or neurological deficits.
