Case in brief
A male newborn, born at 31 1/7 weeks gestation, presented with respiratory distress and varus deformity of the lower extremities. Radiographic findings revealed diffuse osteosclerosis in long bones. Notably, serum alkaline phosphatase levels increased rapidly, prompting further investigation. Chromosomal microarray analysis identified a homozygous deletion in the TNFRSF11B gene, confirming a diagnosis of Juvenile Paget disease.
Diagnostic / clinical pearl
Juvenile Paget disease should be considered in neonates presenting with bone deformities and significant increases in alkaline phosphatase levels.
