Three paediatric patients with reversible cerebral vasoconstriction syndromes.
Reversible cerebral vasoconstriction syndromes (RCVS) occur predominantly in middle-aged women. Only one child with RCVS has ever been reported. We report three boys (aged 10, 16 and 10 years) who had multiple thunderclap headaches, including one boy with bath-related attacks. None of them had secondary causes. All their magnetic resonance angiography demonstrated reversible cerebral vasoconstrictions of the major arteries with increased cerebral blood flow velocities on transcranial colour-coded sonography studies. Two of the three had hypertensive surges during headache attacks. None of the three boys had seizure, stroke or other neurological deficits. However, a left occipital subcortical lesion of unknown nature was noted in one boy. The efficacy of calcium channel blockers was variable in these three boys. This report suggests that, although rare, RCVS should be considered in paediatric patients if they present with a history of multiple attacks of thunderclap headache.
