An unusual cause of thunderclap headache after eating the hottest pepper in the world – The Carolina Reaper

摘要

A 34-year-old man with no significant medical history presented to the emergency room (ER) after an episode of thunderclap headache. His symptoms began with dry heaves but no vomiting immediately after participation in a hot pepper contest where he ate one ‘Carolina Reaper,’ the hottest chili pepper in the world. He then developed intense neck and occipital head pain that became holocephalic. During the next few days, on at least two occasions and in retrospect he thought probably more often, he experienced brief intense thunderclap headaches lasting seconds. The pain was excruciating and thus he came to the ER. He denied any focal tingling sensation or weakness, slurred speech, or transient loss of vision. Physical examination revealed blood pressure of 134/69 mm Hg and no neurological deficits. Urine drug screen and non-contrast CT head and neck were unremarkable. CT angiography revealed no aneurysm but demonstrated unexpected multifocal luminal narrowing in the left supraclinoid internal carotid artery, M1 segment of bilateral middle cerebral arteries, and P1 segments of bilateral posterior cerebral arteries consistent with vasospasm ( ). A presumptive diagnosis of thunderclap headache secondary to reversible cerebral vasoconstriction syndrome (RCVS) was made based on the clinical presentation of a severe acute headache, exclusion of aneurysmal subarachnoid haemorrhage, and segmental cerebral arterial vasoconstriction on CT angiography. Our patient’s symptoms improved with supportive care, he had no further thunderclap headaches, and repeat CT angiography 5 weeks later demonstrated resolution of luminal narrowing consistent with RCVS ( ).
