Background Inflammatory myofibroblastic tumor (IMT) and some types of immunoglobulin (Ig) G4‐related disease are often involved in the spectrum of inflammatory pseudotumor (IPT) and the concept of IgG4‐related IPT/IMT has recently been proposed. Methods A 38‐year‐old man complained of initial symptoms of blurred vision and headache. Results A tumor was found in the right mastoid, which caused occlusion of the right sigmoid sinus and intracranial hypertension. A diagnosis of IMT with IgG4+ plasma cell infiltration was established by surgical, pathological, and immunohistochemistry findings. His symptoms were completely relieved after corticosteroid therapy and no recurrence was detected during 22 months of follow‐up. Conclusion A case with cerebral venous sinus infiltrated by IMTs in the head and neck has never been reported; corticosteroid therapy proved satisfactory in IMT with IgG4+ plasma cell infiltration. © 2014 Wiley Periodicals, Inc.
