Anaesthetic management of a dopamine-secreting phaeochromocytoma.

Pheochromocytomas are rare neuroendocrine tumors that arise from chromaffin cells of the adrenal medulla. Most adrenal pheochromocytomas secrete norepinephrine and epinephrine. Dopamine secreting pheochromocytomas are extremely rare and differs from classic pheochromocytomas in clinical features, posing a significant diagnostic challenge. A 41-year-old women presented to our emergency department because of acute flank colic pain and normotension. The screening abdominal computed tomography scan revealed a left adrenal mass. The laboratory test showed significantly increase in plasma dopamine and 24-h urine dopamine. During surgical removal the patient remained hypotensive requiring doses of norepinephrine. The patient presented significant hypertensive responde during direct laryngoscopy and intubation.
