Anterior pituitary lobe atrophy as late complication of hemorrhagic fever with renal syndrome

Abstract

Introduction. Hemorrhagic fever with renal syndrome (HFRS) is acute infective multisystemic disease followed by febrility, hemorrhages and acute renal insufficiency. Bleeding in the anterior pituitary lobe leading to tissue necrosis occurs in acute stage of severe clinical forms of HFRS, while atrophy of the anterior pituitary lobe with diminution of the gland function occurs after recovery stage. Case report. We presented a patient with the development of chronic renal insufficiency and hypopituitarism as complication that had been diagnosed six years after Hantavirus infection. Magnetic resonance of the pituitary gland revealed atrophy and empty sella turcica. Conclusion. Regarding frequency of this viral infection and its endemic character in some parts of our country partial and/or complete loss of pituitary function should be considered during the late stage of HFRS.
