Lobar Emphysema 3 (Differential Diagnosis RDS)

atno_13a_n.jpg: Bronchogram of a 6-month-old boy with progressive respiratory signs and symptoms. The right upper lobe bronchus is only recognizable as a stump which does not continue into a normal bronchial system as it does on the left side. The bronchi of the right middle and lower lobe lie close together and are displaced downwards and to the midline. The cause of the progressive respiratory signs and symptoms is an advanced lobar emphysema of the right upper lobe. The site of the malformative valve mechanism is in the stump of the depicted upper lobe brochus !£atno_13a_p£! $$atno_10??££Picture for comparison§§ . The bundling of the bronchi of the right middle and lower lobe corresponds to an atelectasis due to compression. atno_13b_n.jpg: After thoracotomy the right upper lobe springs out of the thoracic incision. Compared with the partially visible middle lobe (whose atelectasis has been corrected in the meantime by the anesthesiologist), the overinflation of the macroscopically nearly normal appearing right upper lobe is distinctly recognizable; notice the gross lung structure of the right upper lobe.
