Reversible cerebral vasoconstriction syndrome

ORPHA:284388Clinical syndrome

Also called RCVS

What it is

A rare cerebrovascular disorder characterized by severe headaches with or without focal neurological deficits or seizures, and a reversible segmental and multifocal vasoconstriction of cerebral arteries. It may occur spontaneously or be provoked by various precipitating factors, the most common being postpartum and exposure to various vasoactive substances such as illicit drugs and selective serotonin-reuptake inhibitors. The major complication is ischemic or hemorrhagic stroke.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.

ICD-10 codes

I67.8filed under a broader ICD-10 category — shared with 8 other rare diseases

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
