title: Cardiac Involvement in Von Hippel-Lindau Disease.
abstract: OBJECTIVE
  The aim of this case report was to highlight the importance of ruling out pheochromocytoma in a patient with Von Hippel-Lindau disease (VHL) and cardiovascular manifestations.
  
  
  METHODS
  A 22-year-old woman with type IIb VHL presented with signs and symptoms of acute decompensated heart failure. Transthoracic echocardiography showed a dilated left ventricle with severely depressed ejection fraction, confirmed by MRI. Urinary catecholamine and metanephrine tests had elevated levels and an abdominal MRI showed the presence of two cystic masses at the left hypochondrium. Surgical resection of both masses was performed, confirming the diagnosis of pheochromocytoma and clear cell renal carcinoma on histology. Six-month echocardiography showed a left ventricle with normal diameters and preserved ejection fraction. Genetic analysis revealed a germline mutation (exon 3 deletion of VHL). As there was no family history of VHL, it was determined to be a de novo mutation.
  
  
  CONCLUSIONS
  This case report showed an atypical manifestation in a patient with VHL and underlines the importance of screening for pheochromocytoma in such patients.
