Round atelectasis

Case Discussion

Round atelectasis.

Case courtesy of Dr Laura Jimenez Juan.

On soft tissue windows, the mediastinal nodes-mainly right paratracheal-present on the previous study, have decreased slightly in size. There is no new mediastinal or chest wall adenopathy.

The right sided pleural effusion is encased in thickened slightly enhancing pleura and has not changed significantly.

The consolidated/atelectatic right lower lobe has partially re-aerated and is responsible for the opacity suggesting a mass on the December radiograph.

Again noted is cardiomegaly with coronary artery and aortic valve calcification. The chronic airway changes in the right apex are unchanged.


Chronic right encapsulated pleural collection. Empyema is a consideration even though the attenuation is somewhat low. Rounded atelectasis of the right lower lobe.
