Introduction

An 18yr old male who was infected with Lassa fever(LF) and complicated by Acute kidney injury(AKI) and massive proteinuria with reversal of albumin-globulin ratio in the acute phase of the illness. He presented with oliguria, generalized body swelling and uraemia. There was no previous risk factor for kidney disease. He recovered from the Lassa fever infection and renal failure but continued to have proteinuria for six months after discharge. LF patients who recovered from AKI were previously believed to be without any adverse sequelae and long duration follow up and long term follow was not a routine practice. The index patient had five sessions of hemodialysis and received human albumin transfusion for severe hypoalbuminaemia. He made a complete clinical recovery and followed up.
