Acute Lymphoblastic Leukemia: an Unusual Cause of Bilateral Nephromegaly at Presentation

Acute lymphoblastic leukemia (ALL) is the most common type of cancer in childhood. Renal involvement may occur in 8-16% of patients without clinical manifestation and is detected in the majority of these cases renal involvement is detected after the patient received diagnosis of leukemia.. In this article, we presented a 18 month-old girl presented with abdominal distension and bilateral nephromegaly who was diagnosed with pre-B cell B-cell precursor acute lymphoblastic leukemia, and emphasized that lymphoblastic infiltration should be considered in the differential diagnosis of a patient presenting with unexplained nephromegaly.
