Reticular Patterns

Upper Lobe Reticular Pattern : C-A-S-S-E-T

Lower Lobe Reticular Pattern : B-A-D-L-A-S-S

Diffuse Fine Reticular Densities:

(From Chest Radiology: Plain film patterns and differential diagnoses by James C. Reed)

This pattern must be distinguished from the normal pattern of blood vessels. The best way to do this is to demonstrate the presence of Kerley B lines which represent thickening of the interlobular septa that extend to the pleural surface.

Acute Etiologies:

1. Pulmonary Edema:

Pulmonary interstitial edema is probably the most common cause of a diffuse, fine reticular pattern

A. Cardiogenic

B. Non-cardiogenic:

  • Uremia
  • Fluid Overload
  • Severe hypoproteinemia: Cirrhosis and nephrosis

2. Infection:

Chronic Etiologies:

1. Chronic Pulmonary Edema:

2. Collagen Vascular Disease:

3. Inhalational Lung Disease:

  • Asbestosis
  • Silicosis (More commonly has a combination of small nodules and fine reticulations)

4. Idiopathic Causes:

5. Granulomatous disease:

  • Sarcoid (More commonly presents with small, nodular densities)

6. Lymphangetic metastases

7. Lymphatic Obstruction
