[Hyperthyroidism associated with pulmonary hypertension].

The association of pulmonary hypertension and polyendocrinopathies or connective tissue diseases has been reported by several authors. The causes of this form of pulmonary hypertension are not clear but an autoimmune process has often been proposed. The authors report a case of non-autoimmune hyperthyroidism and reversible pulmonary hypertension after total thyroidectomy and normalisation of thyroid function. This case supports the hypothesis of a non-autoimmune aetiology of some causes of pulmonary hypertension in diseases of the thyroid.
