Reversible Cerebral Vasoconstriction Syndrome in Children and Adolescents: A Case Series and Literature Review

Abstract

Reversible cerebral vasoconstriction syndrome (RCVS) is a complex neurovascular and clinical radiological syndrome characterized by multiple headaches, particularly thunderclap headaches, which may be accompanied by other neurological symptoms. This syndrome involves reversible diffuse vasoconstriction of the cerebral vessels [1,2]. Typically, these vasoconstrictions begin in the peripheral arterioles and progress centripetally to larger vessels over a span of days [3]. They typically resolve within 3 months of clinical onset [4].
