title: Delayed Positivization of Cerebral Angiography in Reversible Cerebral Vasoconstriction Syndrome (RCVS) Presenting with Recurrent Subarachnoid Haemorrhage.
abstract: Benign angiopathy of the central nervous system is a clinical syndrome with evidence of reversible cerebral vasoconstriction (RCVS). Haemorrhagic stroke, either subarachnoid or intracerebral is an unusual presentation of RCVS. We describe a case of RCVS presenting with a subarachnoid haemorrhage (SAH), with rebleeding and onset of hydrocephalus during the first week, and, notably, delayed evidence of typical angiographic features after two negative prior exams. Normalization of the angiographic vasculitic-like lesions was documented at month +6. Repeated cerebral angiograms are mandatory to exclude this kind of disease, and the uncommon presentation of this case reinforces this concept.
