ベーチェット病
There are two types of neuro-Behçet's disease: parenchymal and non-parenchymal. The two types of neuro-Behçet's disease rarely occur in the same person. It is suggested that the pathogenesis of the two types are probably different.[3] Statistics indicate that approximately 75% (772 of 1031) BD patients advanced to parenchymal NBD while 17.7% (183 of 1031) of BD patients advanced to non-parenchymal NBD. The remaining 7.3% were not able to be categorized.
