[Notes on the differential diagnosis of nodules in the lung: Rendu-Osler-Weber disease (author's transl)].

The hereditary hemorrhagic teleangiectasia, commonly known as "Rendu-Osler-Weber" disease, is a relatively seldom found affection manifesting itself by the formations of localized arteriovenous capillary connections which are tiny arteriovenous fistulas. They are found in the skin, the mucous membranes and in nearly all organs of the body. The diseases is transmitted by a dominant character. Affections of the lung can be seen in 89% of the cases (1). In the following paper five exemplary cases are to show that the simple radiological method of the roentgenogram of the thorax taken in the frontal projection and in the lateral view, assisted by the conventional tomography in most cases will bring the last diagnosis. In the differential diagnosis nodules in the lung can be delimited by the connecting arteries and veins.
