Bilateral massive nephromegaly–A rare presentation of t-cell acute lymphoblastic leukemia

摘要

IntroductionRenal infiltration by leukemia causing massive bilateral nephromegaly is an extremely rare presentation of T-cell acute lymphoblastic leukemia(T-ALL).Case report18-month-old female toddler presented with fever and progressive abdominal distension of 4–6 weeks duration. Imaging revealed bilateral massively enlarged kidneys with normal excretion. Peripheral blood counts and smear examination was unremarkable and immunophenotypic evaluation of marrow was consistent with T-ALL. Chest imaging was unremarkable. She was started on modified Indian Childhood Collaborative Leukemia Group (ICiCLe) ALL protocol. Even with the best anti-tumor lysis syndrome (TLS) prophylaxis the child required two sessions of hemodialysis. An end-induction morphological remission & end-consolidation negative minimal residual disease (MRD) could be achieved.ConclusionBilateral massive nephromegaly is an extremely rare presentation of T-ALL. This case emphasizes the unusual presentation, need for prompt remediation of TLS, and most importantly the use of early intensification with four drug anthracycline & dexamethasone-based therapy for the treatment of T-ALL in children.
