Page kidney due to a renal pseudocyst in a setting of pancreatitis. Pancreatic pseudocysts are notorious for their extension beyond the normal confines of the pancreatic bed due to dissection of the enzymatic pseudocyst fluid along fascial planes. Such collections of pancreatic juice may compress the kidney. Extension of the pseudocyst into the perirenal space is, however, uncommon. We report a case of pseudocyst of pancreas lying in the subcapsular plane of the left kidney with a patent communication with the pancreatic duct (pancreaticorenal fistula). The compressive effect of the pseudocyst on the kidney compromised intrarenal perfusion as evidenced by a faint nephrogram but a normal renal artery. This led to renin-angiotensin-aldosterone mediated hypertension-the Page kidney phenomenon. Extensive literature search revealed our case to be the only one to describe such an occurrence.
