Abstract
Acute myeloid leukemia (AML) accounts for 16% of all leukemias in children. Prognosis in the pediatric population is better than that of older populations, with a younger age at diagnosis being a favorable prognostic factor [1]. Diplopia is a rare first presenting sign of AML. We present a 15 year old male complaining of diplopia and unilateral orbital swelling. Workup in the emergency department found normal neuroimaging but revealed a markedly elevated leukocytosis with anemia and thrombocytopenia. Peripheral smear showed increased blast cells >10%. This patient was ultimately diagnosed with AML. This case demonstrates an atypical presentation of AML and urges a thorough work up for patients presenting with unexplained diplopia.
