Hoarseness is a common clinical condition with underlying causes which can vary from reversible and benign to life-threatening and malignant. Cardiovocal syndrome may cause hoarseness secondary to left recurrent laryngeal nerve palsy when the recurrent laryngeal nerve is mechanically affected due to enlarged cardiovascular structures. We report a 28-year-old male who presented to the Government Medical College, Thiruvananthapuram, India, in 2013 with hoarseness. He had undergone irregular treatment for pulmonary tuberculosis (TB) two years previously. Fiber-optic laryngoscopy indicated left vocal cord palsy and a computed tomography scan of the chest revealed features of pulmonary hypertension with extensive enlargement of the pulmonary arteries. An echocardiogram confirmed severe pulmonary arterial hypertension with severe tricuspid regurgitation. He was diagnosed with left recurrent laryngeal palsy secondary to cardiovocal syndrome. Although reports exist of recurrent laryngeal palsy in TB, this case appears to be the first to report cardiovocal syndrome in a patient treated for pulmonary TB.
Cardiovocal SyndromeA rare cause of hoarseness in a patient with a history of pulmonary tuberculosis
Case ReportA 28-year-old male was admitted to the Government Medical College, Thiruvananthapuram, India, in 2013 with hoarseness persisting for three months. He also complained of a history of dyspnoea both upon moderate exertion during the last year and at rest over the past two days. He did not report any symptoms of coughing, haemoptysis, difficulty in swallowing, paroxysmal nocturnal dyspnoea, rheumatic fever or previous surgical interventions or trauma to the head and neck region. Two years previously, he had been diagnosed with open pulmonary TB and was prescribed a regimen of antitubercular therapy including isoniazid, rifampicin, pyrazinamide and
