Article Abstract
Objective: To assess the rate of detection of pulmonary nodules on preoperative computed tomography, based on intraoperative palpation of non-imaged pulmonary nodules, in patients who underwent thoracotomy for metastasectomy with bimanual lung palpation.
Methods: A retrospective study carried out on all cases of pulmonary metastasectomy performed in King Faisal Specialist Hospital and Research Center over a 10-year period (2001-2011). The number of nodules detected on preoperative computed tomography by a radiologist was compared with the number of nodules identified on pathology. Resected pulmonary nodules were classified to benign or malignant. Secondary outcomes were operative approach and primary malignancy.
Results: 215 metastasectomies were performed by thoracotomy. The incidence of nodules that were not imaged preoperatively was 36% (41% of mesenchymal tumors, 28% of epithelial tumors).
Conclusion: Metastasectomy by an open approach, which affords bimanual palpation of the entire lung, discovered ipsilateral non-imaged malignant pulmonary metastases in 36% of cases (41% of mesenchymal tumors).

Introduction: Amyloidosis, a polymeric deposition disease classified according to protein subtype, may have varied pulmonary manifestations. Its anatomic-radiologic phenotypes include nodular, cystic, alveolar-septal, and tracheobronchial forms. Clinical presentation may range from asymptomatic parenchymal nodules to respiratory failure from diffuse parenchymal infiltration or diaphragmatic deposition.

Ambient air pollution is an important contributor to increasing cases of lung cancer, which is a malignant cancer with the highest mortality among all cancers. It primarily manifests in the form of pulmonary nodules, but not all will develop into lung cancer. Therefore, it is highly desired to distinguish between benign and malignant pulmonary nodules for the early prevention and treatment of lung cancer.

Patients And Methods: We retrospectively analyzed 57,119 individuals who underwent health checkups at the People's Hospital of Guangxi from May 2020 to May 2024.
Assessment of intratumor heterogeneity for preoperatively predicting the invasiveness of pulmonary adenocarcinomas manifesting as pure ground-glass nodules.
Quant Imaging Med Surg

Department of Clinical Engineering, Nanfang Hospital, Southern Medical University, Guangzhou, China.
Background: The increased use of low-dose computed tomography (CT) for lung cancer screening has improved the detection of ground-glass nodules. However, as the clinical utility of CT findings to predict the invasiveness of pure ground-glass nodules (pGGNs) is currently limited, differentiating pGGNs that indicate invasive adenocarcinoma (IAC) from those that represent other histological entities is challenging. We aimed to quantify intratumor heterogeneity of lung adenocarcinomas characterized by pGGNs on CT to assess its efficacy in predicting IACs before surgery.
