RT Journal Article SR Electronic T1 Reversible cerebral vasoconstriction syndrome: a rare cause of postpartum headache JF Practical Neurology JO Pract Neurol FD BMJ Publishing Group Ltd SP 141 OP 144 DO 10.1136/practneurol-2014-000997 VO 15 IS 2 A1 Wiles, Kate S A1 Nortley, Ross A1 Siddiqui, Ata A1 Holmes, Paul A1 Nelson-Piercy, Catherine YR 2015 UL http://pn.bmj.com/content/15/2/141.abstract AB We describe two women presenting with severe postpartum headache associated with hypertension but with no other signs or investigation results to suggest pre-eclampsia. In one case, the headache was associated with atypical subarachnoid haemorrhage. The variable nature of the headache and the degree of associated hypertension raised the clinical suspicion of reversible cerebral vasoconstriction syndrome, confirmed on MR angiography. Both patients took nimodipine until the cerebral vasoconstriction had resolved radiologically.
