Pheochromocytoma presenting with pulmonary edema and hyperamylasemia.
Additional Document Info
A 28-year-old woman was admitted to hospital with acute pulmonary edema, mild abdominal discomfort and hyperamylasemia. From the 2nd hospital day hypertensive episodes occurred daily. The furosemide screening test for renovascular hypertension revealed elevated plasma renin activity (PRA) but an intravenous pyelogram revealed a right suprarenal mass and no evidence of renovascular compression. Elevated values of plasma and urinary catecholamines indicated a pheochromocytoma, and a single chromaffin tumour was resected. It is important to monitor left ventricular filling pressure during operative removal of a pheochromocytoma. Postoperatively the patient had normal blood pressure and PRA. Decreased urinary amylase clearance and abnormal pancreatic and salivary amylase isoenzymes were found.
