The presence of an unsuspected phaeochromocytoma in a patient undergoing elective coronary artery bypass grafting provides an unusual challenge for the anaesthetist. We report our detection and management of a phaeochromocytoma in an unprepared patient.Case report A 65-year-old male with recent onset of rest angina was scheduled for elective coronary artery bypass grafting. He had an eight-year history of mild essential hypertension, treated only with betablockade. He had sustained two uncomplicated myocardial infarctions, eight and seven years prior to admission. His medications included metoprolol 25 mg BID, sulfinpyrazine, ASA, and sublingual nitroglycerin. Angiography revealed 80-90 per cent proximal obstruction of all three major coronary arteries and an ejection fraction of 0.80. Examination revealed a 72 kg male with a blood pressure of 150/90 mmHg and a heart rate of 60 beats.min -1. Physical examination was unremarkable. The electrocardiogram showed sinus rhythm, evidence of an old infero-posterior infarction, and voltage criteria consistent with left ventricular hypertrophy. The chest x-ray, serum electrolytes, blood urea nitrogen, and creatinine were all normal. The haematocrit was 40 per cent. The fasting blood glucose was mildly elevated to 200 mg.dl-J (normal 80 to 120).The patient was premedicated with morphine 10 mg IM, scopolamine 0.4 mg IM, and metoprolol CAN ANAESTH SOC J 19g6 / 33:6 / pp789-9

“…1,2 Though, the classical triad is severe headache, palpitations and sweating which is seen in 90% of cases, the clinical features could be atypical, mostly in extremes of age. 3 As seen in the present case, this young girl had predominant symptoms of polyphagia and amaurosis fugax with absence of classical triad.…”

Pheochromocytoma is adrenal medullary tumor known to present in protean ways, especially in children. Here we des cribe a case of adrenal pheochromocytoma in young girl of 13 years presenting with polyphagia as a predominant symptom. She was successfully treated with laparoscopic adrenalectomy. Source of support: Nil Conflict of interest: None CASe RepoRTA 13 years old girl presented with history of two self-limiting attacks of transient blackouts (amaurosis fugax) associated with palpitations since 1 month. During one of the episodes, the measured blood pressure was 210/120 mm Hg. She was put on calcium channel blockers and fundus examination showed grade II hypertensive retinopathy. She was referred to us for further treatment as there was history of hypothyroidism too. Further history evoked the striking chief complaint of polyphagia with craving for bizarre foods, beverages and snacks, which were rarely savoured by her in the past. She was craving for non-vegetarian food, ice-creams, pizzas, chalk, raw rice. This craving was more marked at midnights and early mornings. Renal function tests were within normal limits. Computed tomography (CT) of brain and neurological examination was normal. Other causes of secondary hypertension, such as vasogenic and drug intake were excluded. On further evaluation, there were neither stigmata nor family history of MEN syndromes, paraganglioma, Carney's complex, neurofibromatosis or VHL syndrome.

“…4 Hypothermia, used routinely during CPB, has also been reported to provoke catecholamine secretion by pheochromocytoma. 5 By performing off-pump CABG, we avoided the hazardous effects of CPB on pheochromocytoma-induced changes in systemic vascular resistance and hence blood pressure. The use of the off-pump technique resulted in only minimal changes in blood pressure, which occurred during cardiac manipulation and stabilizing device application.…”
