Clinical Aspects of IgG4-Related Orbital Inflammation in a Case Series of Ocular Adnexal Lymphoproliferative Disorders
Figure 3
Representative cases with IgG4-related orbital inflammatory lesions other than lacrimal glands. (a) Enlargements in the left inferior rectus muscle and infraorbital nerve (arrow) in a 65-year-old man with a serum IgG4 of 404 mg/dL (case number 7 in Table 1). (b) Swelling of the left superior and lateral rectus muscles, a mass lesion around the left optic disc (arrow), and enlargements of the left supraorbital nerve and the right infraorbital nerve (arrow heads) were seen in a 60-year-old man with a serum IgG4 of 463 mg/dL (case number 8). (c) Mass lesion around the right optic disc was observed in a 44-year-old man with a serum IgG4 of 599 mg/dL (case number 11). (d) Bilateral supraorbital nerve enlargements (arrows) and right infraorbital nerve enlargement were observed in a 47-year-old woman with a serum IgG4 of 1000 mg/dL (case number 16). Magnetic resonance images are T1-weighted in (b) and (d) and T2-weighted in (a) and (c).
