Primary lung lymphoma (PLL) is a rare type of lymphoma confined to the lung at the time of diagnosis. Pulmonary diffuse large B cells lymphoma (P-DLBCL) is the second most common type of PLL and it usually appears radiologically as solitary or multiple nodules or areas of consolidation. We present the case of a 63-year-old Caucasian male who developed severe acute respiratory failure and diffuse ground glass opacities (GGO) on chest computerized tomography. Diffuse GGO may be the radiological expression of very different diseases, ranging from infectious processes to interstitial lung diseases (ILDs) and neoplastic diseases...

Ground-glass opacity (GGO) is a common CT imaging sign on high-resolution CT, which means the lesion is more likely to be malignant compared to common solid lung nodules. The automatic recognition of GGO CT imaging signs is of great importance for early diagnosis and possible cure of lung cancers. The present GGO recognition methods employ traditional low-level features and system performance improves slowly. Considering the high-performance of CNN model in computer vision field, we proposed an automatic recognition method of 3D GGO CT imaging signs through the fusion of hybrid resampling and layer-wise fine-tuning CNN models in this paper...

BACKGROUND: Lung cancer can be detected in its early stages with computed tomography (CT). Early lung adenocarcinoma often is displayed as ground glass opacity (GGO), an entity that has been well studied over the past decade. However, few studies have focused on the correlation between CT characteristics and pathologic subtype of GGO. We aimed to explore the correlation between CT characteristics, pathologic subtype, and gene mutation associated with GGO in an effort to aid in the treatment of lung adenocarcinoma...

Y Cao, H Xu
Background: We aimed to develop a new EGFR mutation-predictive scoring system to use in screening for EGFR -mutated lung adenocarcinomas (lacs). Methods: The study enrolled 279 patients with lac, including 121 patients with EGFR wild-type tumours and 158 with EGFR -mutated tumours. The Student t-test, chi-square test, or Fisher exact test was applied to discriminate clinical and computed tomography (ct) features between the two groups. Using a principal component analysis (pca) model, we derived predictive coefficients for the presence of EGFR mutation in lac...

Pulmonary ground glass opacity (GGO) is becoming an important clinical dilemma in oncology as its diagnosis in clinical practice is increasing due to the introduction of low dose computed tomography (CT) scan and screening. The incidence of cancer in GGO has been reported as high as 63%. The purpose of this manuscript is to review best available evidence papers on management of GGO in lung cancer to address the following questions: (I) how to correlate CT findings with malignancy; (II) when and who operate? (III) how to perform intraoperative detection of intrapulmonary GGO? (IV) wedge, segmentectomy or lobectomy? Taking a cue from a clinical scenario, a review on PubMed was conducted...

PURPOSE: Intraoperative localization and resection of ill-defined pulmonary ground-glass opacities (GGOs) during minimally invasive pulmonary resection is technically challenging. Current preoperative techniques to facilitate GGO localization include microcoil and hook-wire placement, but have logistic limitations, carry safety concerns, and do not help with margin assessment. In this clinical trial, we explore an alternative method involving near-infrared molecular imaging using a folate receptor-targeted agent, OTL38, to improve localization and margin confirmation of GGOs...

Background: Segmentectomy for small-sized stage Ia non-small cell lung cancer (NSCLC) may be comparable to lobectomy regarding prognosis and local recurrence. However, the clinical results of wedge resection for such patients are still under debate. In this international multicenter study, we retrospectively studied surgical outcomes of sublobar resections for patients with small-sized stage Ia adenocarcinoma to elucidate whether wedge resection is inferior to segmentectomy for such patients...

Radiological findings of pulmonary infarction have been well characterized mainly in established infarction. However, the early course CT appearance of patients who develop pulmonary infarction has not yet been fully elucidated. A 50-year-old female with a history of postmenopausal hormone replacement therapy (HRT) presented with dry cough and high-resolution computed tomography (HRCT) findings of fan-shaped segmental ground-glass opacity (GGO) in the right lower lobe. As the parenchymal density in the GGO gradually enlarged over a period of 4 weeks in spite of antibiotic treatment, the patient was referred to our hospital on clinical suspicion of bronchioloalveolar cell carcinoma...

Due to emphasis on early screening for lung cancer, the detection rate of multiple ground glass opacities (GGOs) on computed tomography (CT) image increases in recent years, and research on multifocal adenocarcinomas presented by GGOs has been thriving. It is more common in women and non-smokers and has excellent prognosis both in patients with natural history and after surgery. These clinical features suggest that it is likely to be a distinct disease entity. From the perspective of molecular genetics, lesions in the same individual are likely to have distinct clonal features...
