Case in brief

A 55-year-old woman presented with recurrent thunderclap headaches precipitated by bathing, showering, and the Valsalva maneuver. Laboratory testing showed hyperthyroidism, and brain MRI demonstrated convexity subarachnoid hemorrhage and cerebral arterial vasospasm. She was diagnosed with reversible cerebral vasoconstriction syndrome (RCVS) alongside hyperthyroidism. The report discusses the possible association between RCVS and thyroid function; the abstract does not describe treatment or clinical resolution.

What made this case unusual

RCVS occurred in a patient with hyperthyroidism, an association the authors note has received limited attention in the literature.

Diagnostic / clinical pearl

Recurrent thunderclap headache with convexity subarachnoid hemorrhage and cerebral arterial vasospasm should prompt consideration of RCVS; this case also documents coexisting hyperthyroidism.
