{Abstract}: Central diabetes insipidus (DI) is a rare complication in patients with acute myeloid leukemia (AML), typically occurring in patients with abnormalities of chromosomes 3 or 7. The association between AML with monosomy 7 and DI has been described in a number of studies; however, DI has been rarely reported in cases of ectopic virus integration site-1 (EVI1)-positive AML with monosomy 7. The current study reports a case of AML with monosomy 7 and EVI1 overexpression, with central DI as the initial symptom. The patient was an 18-year-old female who presented with polyuria and polydipsia. Bone marrow aspiration revealed 83.5% myeloperoxidase-positive blasts without trilineage myelodysplasia. The karyotype was 45,XX,-7, and the patient presented monosomy 7 and EVI1 overexpression (-7/EVI1+) without 3q aberration. Treatment with induction therapy was unsuccessful. To the best of our knowledge, this is the second case of DI-AML with -7/EVI1+ and without a 3q aberration. The possible mechanisms associated with EVI1, monosomy 7 and DI were investigated.
