Hypertensive encephalopathy in a patient with retroperitoneal fibrosis

Abstract

A patient presented with retroperitoneal fibrosis but without any ureteric obstruction. The diagnosis was made by an abdominal CT scan and also at laparotomy. Post-operatively, she developed hypertensive encephalopathy. An isotope renogram with captopril was abnormal but not diagnostic of renal artery stenosis. The patient's condition improved with steroid and antihypertensive treatment. A follow-up CT scan showed complete resolution of peri-aortic thickening. A causative link is postulated between retroperitoneal fibrosis, trauma during laparotmy, and onset of acute hypertension.
