We report a case of pulmonary hypertension in a patient with non-cirrhotic portal hypertension and scleroderma sine scleroderma. The two latter conditions have been shown to be independently associated with pulmonary arterial hypertension. DLCO is expected to decrease in scleroderma patients due to pulmonary vascular disease, which will result in an increased FVC/DLCO ratio. The low FVC/DLCO ratio in our patient suggests that pulmonary arterial hypertension was more likely to have been due to non-cirrhotic portal hypertension than scleroderma sine scleroderma.
