A Rare Case of Intravenously Managed Hypertensive Emergency Arising from a Perirenal Hematoma Subsequent to a Native Kidney Biopsy

Abstract

Page kidney is a pathologic and rare occurrence caused by a compression of renal parenchyma leading to hypertension. When infiltrated or engulfed by extrinsic matter, the subcapsular region surrounding the renal tissue may cause blanket compression, leading to the activation of the renin-angiotensin-aldosterone system secondary to renal hypoperfusion. While most cases of Page kidney are secondary to blunt trauma to the costovertebral angle, herein we present a case of Page kidney due to renal parenchymal core needle biopsy. The rarity of our case is not due to the cause of such an incidence but because our case resulted in a hypertensive emergency treated with dual intravenous infusions.
