X Ray Kerley B Lines Chest X ray

Although this is not commonly tested in USMLE Step 2 CK as I think but it's a good idea to see how do these look like on CXR.

Have a look here

In the above image, they are specially prominent on the right lower lung field.

Good to remember that there are 2 main DDx for the kerley B lines on CXR:
1- heart failure
2- carsinomatose lymphangitis

Default Lymphangitic Carcinomatosis

Lymphangitic Carcinomatosis

LC occurs as a result of the initial hematogenous spread of tumor to the lungs, with subsequent malignant invasion through the vessel wall into the pulmonary interstitium and lymphatics. Tumor then proliferates and easily spreads through these low-resistance channels. Less commonly, direct infiltration occurs as a result of contiguous mediastinal or hilar lymphadenopathy or an adjacent primary bronchogenic carcinoma.

On radiographs, LC appears as reticular or reticulonodular opacification, often with associated septal lines (Kerley A and B lines), peribronchial cuffing, pleural effusions, and mediastinal and/or hilar lymphadenopathy (20-50% of cases).
