Atypical adenomatous hyperplasia is a premalignant lesion reflecting a focal proliferation of atypical cells. These lesions are usually observed as incidental findings in lungs that have been resected due to other conditions, such as lung cancer. We report the youngest case of atypical adenomatous hyperplasia on record in a 12-year-old girl. In this patient, the lesion was found in association with pneumothorax.

Background: A ground glass nodule (GGN) is a radiologically descriptive term for a lung parenchymal area with increased attenuation and preserved bronchial and vascular structures. GGNs are further divided into pure versus subsolid lesions. The differential diagnosis for GGNs is wide and contains a malignant possibility for a lung adenocarcinoma precursor or tumor.

Objective: The aim of this study is to analyze the correlation between [18F]-FDG PET/CT (positron emission tomography/computed tomography) findings and pathological subtypes of lung adenocarcinoma with ground-glass opacity (GGO).
Materials And Methods: 88 patients were included in this study, which underwent [18F]-FDG PET/CT and were finally diagnosed with lung adenocarcinoma. A total of 90 GGO lesions were analyzed.

Background: The assessment of lung adenocarcinoma significantly depends on the proportion of solid components in lung nodules. Traditional one-dimensional consolidation tumor ratio (1D CTR) based on ideal, uniformly dense solid components lacks precision. There is no consensus on the CT threshold for evaluating invasiveness using the threshold segmentation method.

Background: Limited research exists on screening thresholds for low-dose CT in detecting malignant pure ground-glass lung nodules (pGGNs) in the Chinese population.
Materials And Methods: A retrospective analysis of the Guangzhou Lung-Care programme was conducted, retrieving average transverse diameter, location, histopathology, frequency and follow-up intervals. Diagnostic performances for 'lung cancers' were evaluated using areas under the curve (AUCs), decision curve analysis (DCA), sensitivities and specificities, with thresholds ranging from 5 mm to 10 mm.

Background: This study explores the value of interlobar fissure semilunar sign(IFSS) based on multifactor joint analysis in predicting the invasiveness of ground glass nodules(GGNs) with interlobar fissure attachment in the lungs.
Methods: This was a retrospective analysis of clinical data and CT images of 203 GGNs attached to the interlobar fissures confirmed by surgery and pathology. According to pathological results, those GGNs were divided into three groups: glandular precursor lesion (atypical adenomatous hyperplasia/adenocarcinoma in situ), minimally invasive adenocarcinoma (MIA), and invasive adenocarcinoma (IAC).
