BACKGROUND: Pheochromocytomas are rare tumors originating in chromaffin cells which predominantly are located in adrenal glands. Sustained or paroxysmal hypertension (HT) is the most frequent sign of pheochromocytoma. In some cases, it is associated with the classic triad including episodic headaches, sudoresis, and tachycardia; however, we present a case of pheochromocytoma with first presentation of cardiomyopathy.
CASE PRESENTATION: The authors describe a rare case of a pheochromocytoma which was first presented with cardiomyopathy in a 7-year-old patient. The patient was admitted with malaise, abdominal pain, polydipsia, and myalgia. Further evaluations revealed hyperglycemia, mild dehydration and sinus tachycardia but no HT. Echocardiography demonstrated some of the signs of cardiomyopathy which was incorrectly diagnosed as viral myocarditis. The patient was discharged with this diagnosis but he presented again with HT crisis a few months later. A diagnosis of pheochromocytoma was assigned after the evaluation of the HT secondary causes. The diagnosis was confirmed by metanephrine assay and the tumor was localized in the adrenal gland using the abdominal MRI.
CONCLUSION: Pheochromocytoma can present itself with normotensive cardiomyopathy. Therefore, the possibility of pheochromocytoma should be considered in patients with cardiomyopathy especially in those with positive familial history.
