What is mosaic ground glass attenuation?

Mosaic attenuation is a descriptive term used in describing a patchwork of regions of differing pulmonary attenuation on CT imaging.

What is mosaic attenuation pattern?

Introduction. Mosaic attenuation is an imaging pattern on computed tomography (CT) of the chest that is defined as variable lung attenuation that results in a heterogeneous appearance of the parenchyma.

What does a mosaic pattern in the lungs mean?

This CT mosaic pattern of lung attenuation is a nonspecific finding that can reflect the presence of vascular disease, airway abnormalities, or ground-glass interstitial or air-space infiltrates. However, it is often possible to distinguish among these categories.

How is mosaic attenuation treated?

Pulmonary endarterectomy (PEA) is a choice of treatment in chronic thromboembolic pulmonary hypertension (CTEPH). Mosaic attenuation pattern (MAP) is a radiological finding in CTEPH and there are equivocal findings on its use to determine the intensity of the disease.

Which is the best description of mosaic attenuation?

Mosaic Attenuation. Mosaic attenuation is a CT pattern defined by the Fleischner Society glossary as a “patchwork of regions of differing attenuation seen on CT of the lungs.” It is characterized by heterogeneous lung attenuation with well-defined borders corresponding to the secondary pulmonary lobules.

What does mosaic pattern of lung attenuation mean?

This CT mosaic pattern of lung attenuation is a nonspecific finding that can reflect the presence of vascular disease, airway abnormalitie … Areas of variable lung attenuation forming a “mosaic pattern” are occasionally seen on computed tomography (CT) or high-resolution CT (HRCT) images of the lungs.

What can cause a mosaic pattern in ground glass?

Diffuse ground-glass opacity can result in a mosaic pattern related to a number of processes in acute (eg, infection, pulmonary edema), subacute (eg, organizing pneumonia), or chronic (eg, fibrotic diseases) settings.

What can cause diffuse ground glass opacity?

Diffuse ground-glass opacity can result in a mosaic pattern related to a number of processes in acute (eg, infection, pulmonary edema), subacute (eg, organizing pneumonia), or chronic (eg, fibrotic diseases) settings.
