This is the name of the tagged structure below.
Right paratracheal line.
Distortion suggests Middle mediastinal mass.

The image finding below is classically found in this chronic irreversible lung disease.
Bronchiectasis.
This is the signet ring sign- dilated bronchus next to accompanying pulmonary artery.

The name of the common finding on the image below suggesting a later stage of pulmonary fibrosis. 
Honeycombing

According to the WHO, pulmonary hypertension caused by this mechanism is classified as Group 3.
Pulmonary hypertension secondary to chronic hypoxemia (COPD, sleep apnea, ILD)

300
Name this sign.
Diagnosis?
1.Donut sign

This relatively rare endobronchial tumor shown below can cause increased cortisol levels in your blood.
Carcinoid.
Fun facts:
Cacinoid is rare in adults,however, it is the most common bronchial tumor in children.
Carcinoid almost always occurs distal to the carina.
CT shows an endoluminal bronchial mass with homogeneous arterial enhancement.
