Introduction: Pheochromocytoma is an adrenal gland tumour, which usually produces catecholamines. The classical triad of clinical symptoms consists of palpitations, headaches and profuse sweating. Other symptoms include: hypertension, anxiety, pallor, nausea, weakness. However, it can be asymptomatic. Because of unspecific symptoms the diagnosis of this rare neuroendocrine tumor can be missed or delayed. In differential diagnosis other entities should be considered: essential hypertension, anxiety attack, hyperthyroidism, hypogonadism, hypoglycemia, renal artery stenosis, intracranial lesion, autonomic epilepsy, carcinoid syndrome, use of cocaine or amphetamine.
The final diagnosis is based on biochemical testing of urine or plasma metanephrines and imaging examination (CT, MRI). Although huge improvement in biochemical testing is observed in case of lack of symptoms or nonspecific clinical picture, false positive biochemical results should be excluded.
Case: This study reports a 60-year-old man admitted to the hospital because of a left adrenal tumor (35 x 30mm) found incidentally during abdominal ultrasound examination. The patient complained only of profuse sweating on exertion. He has been treated for hypertension for two years and for depression for 7 years. There was no abnormalities in physical examination. Endocrine work-up revealed elevated urine metanephrines and urine noradrenaline, observed both before and after adrenal surgery. Histopathology report confirmed pheochromocytoma. To exclude drug interferences, depression medication after surgery was withdrawn for one month and repeated results of metanephrines and noradrenaline were normal. As the patient was in good condition with no deterioration of his emotional status clomipramine and minaserin were kept withdrawn and the patients remains without medication.
Conclusion: This case report shows that clinical picture of pheochromocytoma can mimic depression. Diagnosis of pheochromocytoma in patient with depression on medication may be difficult, especially when comes to the assessment of the cure after surgery.
Pheochromocytoma (Pheo) is a tumor that derives from adrenomedullary chromaffin cells which produces mainly catecholamines. It may occur at any age. Pheo is potentially life-threatening disorder that accounts approximately 2-3% incidentally found adrenal lesions. More than 25% of patients with pheochromocytomas have germ line mutation in one of the genes: RET, NF-1, VHL and succinate dehydrogenase complex: SDHB, SDHC, SDHD [1,2].
Usually patients with pheo present with paroxysmal or sustained hypertension. Pheo can be however asymptomatic. The classical triad of symptoms consists of palpitations, headaches and profuse sweating. Other symptoms include: anxiety, pallor, nausea, weakness.
A 60 -year- old man was admitted to the hospital, because of a left adrenal tumor incidentally found during abdominal ultrasound (US). The examination was performed as a follow-up of a prostate hypertrophy. The presence of the adrenal mass was confirmed on computed tomography (CT), which showed 35x30 mm tumor with native density of 40 Hounsfield’s units, what spoke against adrenal adenoma. He has been treated for hypertension for two years with losartan and amlodipine, hyperlipidemia with simvastatin and depression for 7 years with clomipramine and mianserin. The patient complained only of profuse sweating on exertion. The patient presented no symptoms and signs of hypercortisolemia or feminization. He also denied heart palpitation, headache, and weight loss or muscle weakness. There were no abnormalities in physical examination.
As a further imaging work-up magnetic resonance imaging (MRI) was done and revealed left adrenal tumor 25x30mm, without signal loss in out-of-phase what again spoke against adrenal adenoma (Figure 1). The endocrine and biochemical measurements were normal, beside diurnal urinary metanephrines and noradrenaline excretion which was significantly elevated (Table 1). We were aware of possibility of drugs interference with catecholamine measurements. The decision about surgery was however undertaken mainly because of imaging tumor phenotype not corresponding to adenoma, so to avoid patients’ emotional status deterioration before operation the measurements were not repeated after drugs withdrawal. Diagnosis of pheochromocytoma was however likely, so the patient was prepared to surgery with alfa- adrenolitics.
