What does reticular pattern mean?

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).

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 are reticular lines?

The reticular pattern appears as a grid of thin brown lines over a diffuse light-brown background. This is a honeycomb-like structure, consisting of round pigmented lines and lighter hypopigmented holes, forming a subtle pattern that appears in many melanocytic lesions.

What causes reticular shadowing?

Symmetric reticular opacities are typically seen on chest radiographs of patients presenting with ECD. Kerley B lines on the chest radiograph are due to interlobular septal thickening as a result of interstitial lung infiltrate along the lymphatics or lymphatic engorgement from obstruction of the lymph drainage routes.

What is a reticular shadow?

Reticular Radiographic Shadows* The term ‘diffuse’ will be taken to mean scattered more or less uniformly over both lung fields. ‘Nodular’ means giving the impression of being caused by small nodules; that is, consisting of many small, rounded opacities. ‘Reticular’ means pro- ducing an appearance resembling a net.

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 is a globular pattern?

Abstract. Background: Dermoscopically, one of the most common findings in melanocytic lesions is a globular pattern. A regular globular pattern is a common finding in naevi. Melanoma can also show a globular pattern, with globules typically irregular in size, colour and distribution.

What is a Reticulonodular pattern?

What does reticular shadowing mean?

Reticular shadowing – Fibrosis 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’ Chest X-rays can be helpful in monitoring the progression of pulmonary fibrosis.

Does lung scarring show on xray?

A chest X-ray shows images of your chest. This may show the scar tissue typical of pulmonary fibrosis, and it may be useful for monitoring the course of the illness and treatment.

What causes a reticular pattern on a chest radiograph?

A reticular pattern on the radiograph may result from summation of smooth or irregular linear opacities, cystic spaces, or both. In approximately 10% of patients with interstitial lung disease, the chest radiograph is normal.

What does reticular interstitial pattern mean on a CT scan?

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 does reticular infiltrate in lungs mean on chest X ray?

Since your reticular pattern on chest x ray is static with comparison in previous x ray, no need to worry. As this must be old healed scar lesion. As ILD and pneumonia will worsen if not treated. So static reticular pattern suggest healed lesion only.

What causes an irregular pattern of reticular opacities?

Intralobular interstitial thickening results in an irregular reticular pattern smaller in scale than the reticular pattern of interlobular septal thickening. The presence of a few thickened interlobular septa can be seen in a wide variety of diffuse lung diseases and is, in general, a nonspecific finding.
