He presented with Potter phenotype, pulmonary hypoplasia with pneumothorax, systemic hypotension and anuria. He required chest drain insertion and continuous positive airway pressure (CPAP), volume expansion plus inotropic support with persistent renal failure. Mother confirmed olmesartan intake during entire pregnancy. Peritoneal dialysis was started with improvement in renal markers and progressive recovery of renal function.
