Congenital tuberculosis is an infection that is established in the fetus by hematogenous spread or by theaspiration or inhalation of infected amniotic fluid either before or during labor. The diagnosis can be confirmedonly if both the tuberculous nature of the lesion and the antenatal origin of the infection can be proved. Theauthors analysed roentgen find-ings of two cases of pulmonary tuberculosis, thought to be congenital; 1. Diffusedistribution of nodular densities and some confluent densities were seen in the entire lungs in the inital film.The pulmonary markings were decreased in some degree. 2. Air bronchogram was noted. 3. Hepatosplenomegaly wasassociated.
