CaseHPOFreeText: 22-year-old woman who was diagnosed in childhood with type IIb VHL, with known multiple retinal angiomas, pancreatic cysts, and spinal and cerebellar hemangioblastomas. She was admitted to our hospital complaining of progressive dyspnea and palpitations. Physical examination revealed a systolic murmur at the mitral focus with irradiation to the axilla and pulmonary rales. Electrocardiography revealed no remarkable findings, except for sinus tachycardia. Chest X-ray showed signs of pulmonary interstitial edema. The patient was admitted to the Department of Cardiology with the diagnosis of acute decompensated heart failure. Transthoracic echocardiography showed a dilated left ventricle with severely depressed ejection fraction due to generalized hypokinesia and a mild mitral regurgitation. During admission, the patient had several episodes of paroxysmal dyspnea. Cardiac MRI was performed in order to complete the cardiomyopathy study, and confirmed the echocardiographic findings as well as revealed an incidental finding of a great left renal mass. Abdominal MRI was performed, which showed the presence of two cystic masses located at the left hypochondrium confirming the diagnosis of pheochromocytoma and clear cell renal carcinoma on histology.
