Acute dyspnoea resulting from pulmonary oedema as the first sign of a phaeochromocytoma.
The day after undergoing neck dissection, a 42-year-old woman developed acute dyspnoea due to pulmonary oedema. Measurements with a Swan-Ganz catheter revealed not only cardiac depression but also a greatly increased peripheral vascular resistance: 5,400 dyn x s x cm(-5)/m2. A phaeochromocytoma with acute cardiac failure leading to pulmonary oedema was considered. Treatment with alpha- and beta-blockers was complicated by severe hypotension and later ventricular fibrillation. Mechanical ventilation was required for 6 days following resuscitation. Investigation of the urine subsequently showed greatly increased catecholamine concentrations, while imaging revealed bilateral adrenal tumours. Our case history shows that acute pulmonary oedema may be the presenting manifestation of a phaeochromocytoma. The pulmonary oedema resulted partly from backward failure following tachycardia, myocyte necrosis and the greatly increased peripheral vascular resistance, and partly from increased permeability of the capillary network in the lungs.
