Both @entity12787 and @entity1906 are rare disorders of unknown etiology, characterised by @entity32 leading to dense @entity82 . There have been several reports of @entity12787 with @entity1906 . @entity788 is frequently associated with various extrapancreatic lesions, their pathological similarities such as dense inflammatory @entity82 with lymphoplasmacytic infiltration strongly suggests a close relationship between autoimmune @entity788 and @entity12787 . Recently, autoimmune @entity788 including these systemic fibrosing disorders may be classified as IgG4-related @entity262 . However, the relationship between @entity4306 and IgG4-related @entity262 is still uncertain. We performed immunohistochemical examinations in autopsy specimens from a @entity1 with @entity4306 . Histological findings can be summarized as follows: sever interstitial @entity82 and diffuse inflammatory cells infiltration, presenting nonspecific inflammatory changes. Immunohistochemically, diffuse infiltrates in the dura consisted predominantly of @entity5855 positive T or L-26 positive B lymphocytes. Many IgG4 positive plasma cells were also infiltrated. To our knowledge, this may be the first report which showed IgG4 positive plasma cells infiltration in the dura in a @entity1 with @entity4306 . It is postulated that @entity4306 may be a dural lesion of IgG4-related @entity262 .

[Is @entity1906 a dural lesion of IgG4-related XXXX ?].
