Radiculopathy in neuromyelitis optica. How does anti-AQP4 Ab involve PNS?

Pathophysiology of PNS damage in NMOSD might be due to radiculopathy. Although it seems to be rare, radiculopathy may actually be underestimated, and correspondingly underreported, due to its overlap with symptoms of myelitis. Therefore, further evaluation is needed to establish the incidence and pathophysiology of radiculopathy in NMOSD.
