This case report describes a diagnostically challenging presentation of nephrotic syndrome in a two-year-old boy initially suspected to have testicular torsion due to prominent scrotal oedema. The case demonstrates how the characteristic features of nephrotic syndrome – generalised oedema, proteinuria, and hypoalbuminaemia – may be initially obscured by focal symptoms mimicking surgical emergencies. The patient underwent scrotal exploration for suspected appendix testis torsion based on ultrasonography findings; however, postoperative persistence of oedema and development of ascites prompted recognition of the underlying nephrotic syndrome. Prompt initiation of corticosteroid therapy led to rapid resolution of proteinuria and clinical improvement. This report contributes to the existing literature by illustrating how nephrotic syndrome may present atypically, potentially delaying diagnosis when focal symptoms dominate the clinical picture.
