[Severe hypoxemic respiratory insufficiency in a patient with hepato-pulmonary syndrome coexisting with interstitial lung disease of unknown etiology].

The coexistence of the interstitial lung disease and respiratory failure is rarely associated with extrapulmonary pathology. In patients with liver cirrhosis, hypoxemia may develop in the course of hepato-pulmonary syndrome (HPS), but radiological pathology seen in the course of HPS is of vascular origin, and thus typically not classified as interstitial lung disease. We present a patient with severe hypoxemic respiratory insufficiency in whom hepato-pulmonary syndrome coexisted with interstitial lung disease of unknown etiology. The mechanisms of hypoxemia in the course of hepatic diseases and reasons of possible coincidence of lung and hepatic pathology are discussed.
