Intracranial Inflammatory Pseudotumors Associated with Immunoglobulin G4-Related Disease Mimicking Multiple Meningiomas: A Case Report and Review of the Literature

摘要

Immunoglobulin G (IgG)4-related disease is a syndrome that forms inflammatory pseudotumors with increasing IgG4-positive plasma cells and lymphocytes infiltrating the exocrine gland and other organs. The concept of this disease gradually has gained more recognition. However, reports of intracranial pseudotumors associated with IgG4-related disease are very rare. The purpose of this report is to provide further information helpful in distinguishing IgG4-related disease from multiple meningiomas.
