Radiologic characteristics of pulmonary lymphangitic carcinomatosis (6)
Chest radiography
- Coarse bronchovascular markings with irregular outline
- Coarse reticulonodular pattern with intraparenchymal extension of tumour
- Unilateral or bilateral changes predominantly in the lower lobes of the lungs
- Kerley A and B lines
- Hilar and mediastinal lymphadenopathy (20-40% of cases); usually asymmetric
- Pleural effusion (30-50% of cases)
- No abnormalities (30-50% of cases)
Chest CT scan
- Smooth (early stage) and nodular (late stage) thickening of interlobular septa and peribronchovascular interstitium
- Polygonal arcades with thickened limbs from thickened septa of adjacent lobules
- Normal lung architecture is maintained
- Ground-glass appearance from interstitial edema or extension of the tumour into the parenchyma
