Headache. 2001 Feb;41(2):198-200. doi: 10.1046/j.1526-4610.2001.111006198.x.


A 68-year-old woman presented with thunderclap headache, which led to a search for subarachnoid hemorrhage. Both computerized tomography of the head and cerebrospinal fluid examination were normal. Magnetic resonance imaging revealed abnormalities in the white matter in the parieto-occipital regions. There was no aneurysm on magnetic resonance angiography. Treatment of hypertension led to resolution of the posterior leukoencephalopathy. Hypertensive encephalopathy with reversible posterior leukoencephalopathy can present as a thunderclap headache.
