Pheochromocytoma can mimic a number of other diseases, and that's why it is hard 
to diagnose. The classic triad of symptoms are episodic headache, excessive 
sweating and palpitation. Hereby I present a case without any symptoms mentioned 
above. A 58-year-old patient with controlled hypertension without any previous 
complaints connected with respiratory tract, was admitted to hospital because of 
round shadows found in chest X-ray. The attempts to find initial focus as a 
basis of neoplasma failed. Postmortal histologic examination of the adrenal 
glands revealed pheochromocytoma with multiple focuses in lungs and mediastinal 
lymph nodes. Diagnosis pheochromocytoma was as surprising for the physicians as 
for pathologists despite the presence of a small tumor of the left adrenal gland 
found previously in CT scan of the abdomen. In case of presence of "round 
shadows" in lungs connected with changes in adrenal glands one ought to think 
about pheochromosytoma.
