An Unusual Cause of Bilateral Nephromegaly as the Rarely Seen First Presenting Finding of Acute Lymphoblastic Leukemia

Abstract

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 lymphob- lastic leukemia, and emphasized that lymphoblastic infiltra- tion should be considered in the differential diagnosis of a patient presenting with unexplained nephromegaly

Bu makalede karında şişkinlik nedeniyle başvuran, bilateral nefromegalisi olan ve tetkiklerin sonucunda pre B hücreli ALL tanısı alan 18 aylık vaka sunularak nefromega- linin ayırıcı tanısında lösemik infiltrasyonun önemi vurgu- landı
