LINEAR PATTERN
LINEAR PATTERNPerihilar and peripheral basal septal lines,changes acutely and resolves with diuretics
LEFT VENTRICULAR FAILURE
Coarsening of lung markings in lower zones, nochange on review of recent films
Normal ageing
Coarse nodular and linear thickening ofmarkings, known malignancy, often associatedwith pleural effusion, rapid clinicaldeterioration of patient
Lymphangitis
LINEAR PATTERNLINEAR PATTERN
Short thin lines, often basal, new on review ofprevious films
Atelectasis
Longer thicker bands, often perihilar or basal,suggest recent infection or infarction
Subsegmentalcollapse
Any length, persist over time unchanged
Volume loss is key, persists over time
Scarring
Fibrosis
Causes of fibrosisMid zone lung Lower zone lung Upper zone lung
tuberculosis Drug indused fibrosis(most common)
