What is reticular pattern?
The reticular appearance refers to a collection of innumerable small linear opacities that together produce an appearance resembling a “net”. The pattern can be fine, medium or coarse. Fine and medium patterns are shown here. Reticular patterns represent interstitial lung disease.
What does interstitial pattern mean?
An interstitial lung pattern is a regular descriptive term used when reporting a plain chest radiograph. It is the result of the age-old attempt to make the distinction between an interstitial and airspace (alveolar) process to narrow the differential diagnosis.
What does Reticulonodular pattern mean?
A reticulonodular interstitial pattern is an imaging descriptive term that can be used in thoracic radiographs or CT scans when are there is an overlap of reticular shadows with nodular shadows. This may be used to describe a regional pattern or a diffuse pattern throughout the lungs.
What does reticular shadowing mean?
Pulmonary fibrosis causes reticular (net-like) shadowing of the lung peripheries which is typically more prominent towards the lung bases. It may cause the contours of the heart to be less distinct or ‘shaggy’
What’s reticular mean?
adjective. having the form of a net; netlike. intricate or entangled. Anatomy. of or relating to a reticulum.
What does reticular mean?
1. having the form of a net; netlike. 2. intricate or entangled. 3.
What is reticulation in the lungs?
Reticulation results from thickening of the interlobular or intralobular septa and appears as several linear opacities that resemble a mesh or a net on HRCT scans. 7. The presence of reticulation is indicative of interstitial lung disease.
What causes interstitial pattern?
Interstitial lung disease can be caused by long-term exposure to hazardous materials, such as asbestos. Some types of autoimmune diseases, such as rheumatoid arthritis, also can cause interstitial lung disease. In some cases, however, the causes remain unknown. Once lung scarring occurs, it’s generally irreversible.
What is reticular opacity?
In chest radiology, reticular and linear opacification refers to a broad subgroup of pulmonary opacification caused by a decrease in the gas to soft tissue ratio due to a pathological process centered in or around the pulmonary interstitium.
What are subpleural reticular markings?
Subpleural reticulation is a type of reticular interstitial pattern where the changes are typically in a peripheral subpleural distribution (i.e. adjacent to costal pleural surfaces, located ≤1 cm from the pleura according to some publications 4).
What is Reticulonodular infiltration?
The differential diagnosis of diffuse, coarse, reticulonodular pulmonary infiltrates includes collagen vascular diseases such as rheumatoid lung and scleroderma, Gaucher’s disease, drug sensitivity from nitrofurantoin, busulfan, and bleomycin, and inhalation exposure such as silo filler’s disease, silicosis, and …
What is reticular formation?
The reticular formation is a complex network of brainstem nuclei and neurons that serve as a major integration and relay center for many vital brain systems to coordinate functions necessary for survival.
What is a reticular pattern in anatomy?
Reticular. The reticular interstitial pattern refers to a complex network of curvilinear opacities that usually involved the lung diffusely. They can be subdivided by their size (fine, medium or coarse). The subdivision refers to the size of the lucent spaces created by the intersection of lines:
What is a reticular interstitial pattern?
Reticular. The reticular interstitial pattern refers to a complex network of curvilinear opacities that usually involved the lung diffusely. They can be subdivided by their size (fine, medium or coarse). The subdivision refers to the size of the lucent spaces created by the intersection of lines: fine “ground-glass” (1-2 mm): seen in processes…
What is reticulation pattern on HRCT?
Reticular interstitial pattern is one of the patterns of linear opacification in the lung . It can either mean a plain film or HRCT/CT feature. Reticulation can be subdivided by the size of the intervening pulmonary lucency into fine, medium and course.
What is a reticular opacities?
The term reticular is defined as meshed, or in the form of a network. Reticular opacities can be described as fine, medium, or coarse, as the width of the opacities increases.
