DIAGNOSTIC CHALLENGES IN REVERSIBLE CEREBRAL VASOCONSTRICTION SYNDROME (RCVS)

Reversible Cerebral Vasoconstriction Syndrome (RCVS) is a clinical condition characterized by sudden onset severe headache (thunderclap headache) and reversible constriction of cerebral arteries. Because its clinical presentation often mimics other serious neurological disorders, the diagnostic process is frequently complicated. RCVS may be confused with subarachnoid hemorrhage, central nervous system vasculitis, severe migraine variants, or arterial dissection [1–3]. This article analyzes the main diagnostic challenges of RCVS, evaluates the role of modern neuroimaging techniques, and highlights approaches aimed at improving diagnostic accuracy in clinical practice [4,5].
