Page kidney: an unusual complication of image-guided native renal parenchymal biopsy - case report and literature review

Abstract

Page kidney is a pathologic phenomenon in which extrinsic compression of renal parenchyma from a subcapsular collection causes secondary systemic hypertension, via activation of the renin-angiotensin-aldosterone system. Following the first description of Page kidney, the condition was most often recognized following blunt trauma to the flank. Increasingly, non-traumatic and iatrogenic etiologies of Page kidney have been described. We present a case of Page kidney as a complication of image-guided native renal parenchymal core needle biopsy. The current literature on etiologies, pathophysiology, and treatment options for Page kidney are summarized.
