SOSA, Gabriela A et al. Panhipopituitarismo y escotoma perimacular como presentación de enfermedad relacionada a IgG4. Medicina (B. Aires) [online]. 2018, vol.78, n.3, pp.194-196. ISSN 0025-7680.

IgG4-related disease (IgG4-RD) is a recently described systemic entity of unknown origin. It predominantly affects older men and has distinctive histopathologic features as storiform fibrosis, obliterative phlebitis, dense lymphoplasmacytic infiltrate with immunostaining for IgG4, and it may be associated with elevated serum levels of IgG4. Although any organ can be affected, pituitary gland is rarely involved. We describe the case of a 36-year-old man who presented with headaches, impaired vision, panhypopituitarism with diabetes insipidus and an infiltrative lesion mainly of infundibulum and pituitary. We arrived at diagnosis of IgG4-RD by pituitary biopsy. A successful response to treatment with immunosuppressive doses of corticosteroids was achieved.

Keywords : Panhypopituitarism; Hypophysitis; IgG4; Scotoma.
