INTERLOBULAR SEPTAL THICKENING

Interlobular septal thickening is commonly seen in patients with interstitial lung disease. On HRCT, numerous clearly visible septal lines usually indicates the presence of some interstitial abnormality. Septal thickening can be definied as being either smooth, nodular or irregular and each likely represents a different pathologic process.
