COMMON SYMPTOM: UNCOMMON CAUSE

Hoarseness of voice is a very common condition and is caused by recurrent laryngeal nerve palsy. Many possible causes of unilateral vocal cord paralysis are known, including malignant or less often benign tumors, iatrogenic injury, inflammation, or post radiation fibrosis causing nerve palsy due to encasement. Cardiovocal syndrome or Ortner’s syndrome is hoarseness due to left recurrent laryngeal nerve palsy caused mainly by mechanical affection of the nerve from enlarged cardiovascular structures. This interesting case report discusses a patient who developed hoarseness of voice due to venous thromboembolism of pulmonary venous system. Cardiovocal syndrome subsequent to pulmonary hypertension secondary to venous thromboembolism is exceptionally rare.
