Objectives: To describe the characteristics and causes of non-aneurysmal thunderclap headache (TCH) and compare serious from benign underlying causes.
Methods: Retrospective cohort study of consecutive adult patients with TCH presenting to a tertiary care academic medical center between 2010 and 2020. Aneurysmal subarachnoid hemorrhage cases were excluded.
Introduction: Reversible cerebral vasoconstriction syndrome is a clinicoradiological entity with a self-limiting course that manifests with recurrent episodes of thunderclap headache, and is associated with certain triggers. Recurrence is very rare, and the pathophysiology is thought to be related to altered autoregulation of the cerebrovascular tone. We present a clinical case that raises questions about possible recurrences and triggers.

Reversible cerebral vasoconstriction syndrome (RCVS) is a complex and etiologically diverse neurovascular disorder that typically presents with severe thunderclap headaches (TCH) as the primary symptom, accompanied by reversible vasoconstriction of the cerebral arteries. The clinical course may include focal neurological deficits or epileptic seizures. There are two types: idiopathic RCVS and secondary RCVS, the latter triggered by various substances, medical interventions, or diseases.

Thunderclap headache is a sudden severe headache with onset to peak within one minute. Multiple excruciating, short-lived thunderclap headaches over a few days to weeks are highly suggestive of reversible cerebral vasoconstriction syndrome (RCVS). RCVS can be primary or secondary to several factors, but it is rarely described after neuro-endovascular procedures using onyx material.
