How is reversible cerebral vasoconstriction syndrome (RCVS) diagnosed?
The diagnosis of RCVS is based on a person's medical history, symptoms, a complete physical exam, and the results of vascular brain imaging. Such imaging may be in the form of an angiogram, MRA, or CTA scan that can show spasms in blood vessels that are narrowed.
Cerebrospinal fluid testing can help to rule out other conditions that appear to be similar to RCVS. It is important to repeat the vascular imaging to ensure that the spasm that resulted in the diagnosis can be confirmed.
