Massively enlarged kidneys due to leukemic infiltration in a child

A few cases with bilateral renal enlargement in acute lymphoblastic leukemia were reported in literature. In this article, we reported an unusual case of a child with precursor B-ALL presenting with massively enlarged bilateral unobstructed kidneys and acute renal failure. Renal involvement of ALL should be taken into consideration in case with massively enlarged bilateral kidneys in radiological examination. Based on radiological, clinical and laboratory findings including bone marrow aspirate examination, the patient could be diagnosed as ALL without renal biopsy.
