According to the Mayo Clinic, diagnosing of the rare blood disease, Primary Central Nervous System Vasculitis, requires the combined effort of two distinct diagnostic techniques. PCNSV is a rare and unfamiliar blood vessel disorder. This disease often attacks the brain and spinal cord. If not diagnosed and treated promptly, the disease can lead to stroke or death. Identification of this disease is best done by a combination of angiography (imaging of the cerebral arteries) brain biopsy and other laboratory studies.
