Abstract Renal corticomedullary differentiation (CMD) is a crucial indicator of fetal renal health and is detectable as early as 15 to 16 weeks of gestation. Abnormalities in CMD, such as accentuation or loss, may signal underlying renal diseases. CMD assessment via prenatal ultrasound evolves dynamically throughout gestation, reflecting changes in cortical echogenicity and cystic structures. While CMD alterations can indicate conditions like glomerulonephritis or obstructive uropathies, they also offer prognostic insights into future renal function. This case report highlights the importance of early detection and comprehensive evaluation of CMD for optimising prenatal renal care.
