Computed tomography and pathology evaluation of lung ground‑glass opacity

Abstract: The aim of this study was to investigate the pathogenesis of lung ground-glass opacity (GGO) and the diagnostic value of computed tomography scan for lung GGO. Computed tomography (CT) images of 106 lung GGO cases were analyzed retrospectively, and the type, location, size, structure, boundaries and surrounding lung fields were evaluated. There were 12 cases of GGO with a diameter <1.0 cm, 36 cases with diameter of 1.0-1.5 cm, 25 cases with diameter of 1.6-2.0 cm, 19 cases with diameter of 2.0-2.5 cm and 14 ca… Show more

“…Ground-glass opacity (GGO) refers to hazy areas with mildly increased density in lungs, but without obscuration of bronchial and vascular margins, which generally is due to destruction of alveolar walls and lling of the cavity with serous, cells and hemorrhage as well as local interstitial brosis. (7). Consolidation opacity is caused by any pathologic process that diffuse alveolar injury in both lungs with brous mucinous exudate.…”

“…GGO and CLO are the typical lung abnormalities on CT imaging of COVID-19, and are highly heterogeneity at histology and cellular level. GGO lesions can be caused by numerous pathology changes, which generally present as incomplete lling of the alveolar cavity with cells and liquids (such as edema and hemorrhage), or lung interstitial thickening due to in ammation, edema (7). Consolidation opacity is caused from any pathologic process that lls the alveoli with uid, pus, blood, cells or other substances resulting in lobar, diffuse or multifocal ill-de ned opacities.…”

“…Although GGO can be seen in various pathologies, its pattern and distribution along with the clinical picture can favor one diagnosis over the other. The typical findings in patients with negative RT-PCR results can be attribute to other pathologies mimicking the typical CT appearance; such as influenza pneumonia, organizing pneumonia like in drug toxicity and connective tissue disease (20). Recently, new publications aim to differentiate Influenza A from COVID-19 pneumonia by identifying specific CT imaging features (21,22).…”
