Frontal radiograph of the chest (image 1) and coronal CT images (images 2 and 3) MRI in a patient with recurrent respiratory papillomatosis show a cystic lesion within the right upper lobe. On the CT, there are multiple cysts. A hepatoma is visible within the trachea (arrow). Recurrent pulmonary papillomatosis is caused by human papillomavirus. In children, the transmission of human papillomavirus occurs during labor. However, most children born to women with human papillomavirus do not develop recurrent respiratory papillomatosis. Children with recurrent respiratory papillomatosis have multiple solid pulmonary nodules. With time, the nodules cavitate. These patients are at risk of developing squamous cell carcinoma. #ThoraxThursday #ThoracicThursday

Focused chest CT of the left lung apex shows the large apical bleb (arrow) and a small pneumothorax. Blebs are the most common cause of spontaneous pneumothorax in children. Pulmonary blebs occur exclusively in the lung apices. While they don’t always cause pneumothorax, they are a risk factor for the development of a pneumothorax. When present, apical blebs are bilateral in more than three-quarters of patients. Patients with recurrent pneumothorax may be treated with bleb resection. #FridayQuizDay #Quiz #FridayQuiz

Axial (image 1) and coronal (image 2) CT images of the chest in a patient with granulomatosis with polyangiitis show large thick wall pulmonary cysts. Granulomatosis with polyangiitis commonly affects the lungs, the kidneys, and the sinuses. In the lungs, pulmonary nodules with cavitation, pulmonary hemorrhage, and reticular nodular opacities may be present. On CT there are multiple nodules of variable size in a peribronchial vascular distribution. The nodules will frequently cavitate but maintain a thick wall. #ThoraxThursday #ThoracicThursday

Axial contrast-enhanced CT of the chest in a young patient with known respiratory papillomatosis shows numerous pulmonary nodules, some of which are solid (white arrow) and some of which are cavitary with thick wall (black arrows). This disorder is due to vertical transmission of certain types of human papilloma virus during vaginal delivery. Involvement of the lung parenchyma is much less common than involvement of the larynx or tracheobronchial tree. #ThoraxThursday

Frontal chest radiograph (image 1) and axial chest CT (image 2) show a pulmonary abscess (arrow) within the right middle lobe. Pulmonary abscesses are often identified by the presence of air-fluid levels. They are most commonly caused by aspiration. Less frequently, they may result from hematogenous spread of infection. Pulmonary abscesses are more prevalent in immunocompromised patients or those at high risk for aspiration.
