Chronic Eosinophilic Pneumonia (CEP)

Enlarged A-P window Lymph Node  Chronic Eosinophilic Pneumonia (CEP) was made
CT scan in the axial plane performed 6 months ago at the time of clinical presentation shows an enlarged A-P window lymph node likely reactive. Subsequent diagnosis by BAL of chronic eosinophilic pneumonia (CEP) was made

DIP – Mediastinal Adenopathy

Axial CT- Desquamative Interstitial Pneumonia – Mediastinal Adenopathy
60-year-old male smoker with a history of progressive dyspnea. Axial CT through the level of the left pulmonary artery shows borderline enlarged mediastinal lymph nodes.
Pathology of the lung confirmed a diagnosis of DIP

Carcinoma of the Cervix Metastatic Mediastinal Adenopathy Encasement of the Airways

CT Carcinoma of the Cervix Metastatic Mediastinal Adenopathy Encasement of the Airways
33-year-old female with known primary carcinoma of the cervix presents with infiltrating and encasing mediastinal adenopathy with subtotal narrowing of the left main stem bronchus and significant stenosis of the right

Carcinoma of the Cervix Metastatic Mediastinal Adenopathy Encasement of the Pulmonary Arteries

CT Carcinoma of the Cervix Metastatic Mediastinal Adenopathy Encasement of the Pulmonary Arteries
33-year-old female with known primary carcinoma of the cervix presents with infiltrating and encasing mediastinal adenopathy with severe stenosis of both the left (LPA) and right main pulmonary (RPA) arteries. In the upper panel the severe narrowing of the LPA is appreciated and in the lower panel the bilateral severe proximal stenosis is appreciated.

Carcinoma of the Cervix Metastatic Mediastinal Adenopathy Encasement of the Airways with Ball Valve Effect on the Left Upper Bronchus

CT Carcinoma of the Cervix Metastatic Mediastinal Adenopathy Encasement of the Airways with Ball Valve Effect on the Left Upper Bronchus
33-year-old female with known primary carcinoma of the cervix presents with infiltrating and encasing mediastinal adenopathy with severe stenosis of both the left and right main stem bronchi. The upper panels reveal hyperinflation of the left upper lobe (a, b blue arrow heads) likely secondary to air trapping. The lower panel reveals the severe stenosis of the left main stem bronchus (c white arrowhead) with subtotal occlusion appreciated in d, (white arrowhead). This severe subtotal occlusion probably accounts for the hyperinflation secondary to ball valve mechanism

Carcinoma of the Cervix Metastatic Mediastinal Adenopathy – Encasement of the Pulmonary Veins

CT Carcinoma of the Cervix Metastatic Mediastinal Adenopathy – Encasement of the Pulmonary Veins
33-year-old female with known primary carcinoma of the cervix presents with infiltrating and encasing mediastinal adenopathy with stenosis of the bilateral pulmonary veins. The upper panel (a) reveals encasement of the right superior pulmonary vein (a, maroon arrowheads) and compression of the left atrium (white arrowhead). The lower panel b, reveals stenosis of both the superior and inferior pulmonary veins on the right,(maroon arrowheads) and mass effect on the superior aspect of the left atrium (LA) (white arrowhead).
