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 cases with diameter of 2.5‑3.0 cm. There were 20 lesions with a round shape and 68 lesions with an oval shape. There were 56 lesions with spinous processes, 18 lesions with air bronchograms and 37 lesions with surrounding pleural indentation. The diagnosis and differential diagnosis of GGO would be improved with combined CT scan and pathology results.
