We report a case of immunoglobulin G4 (IgG4)-related lung disease presenting as a solitary pulmonary nodule with an irregular margin on computed tomography. The nodule showed a high standardized uptake value on positron emission tomography. A malignant pulmonary tumour could not be excluded. Middle lobectomy was performed. Histological analysis revealed marked lymphoplasmacytic infiltration and storiform fibrosis. Immunostaining indicated the presence of IgG4-positive plasma cells. A definitive diagnosis of IgG4-related disease was confirmed...

REVIEW
Katsuhiro Okuda, Ryoichi Nakanishi
Surgical treatment for lung cancer including airway resection following reconstruction is typically performed under general anesthesia with single-lung ventilation because it is necessary to maintain a sufficient working space and to adjust the airway pressure for the leak test. However, non-intubated thoracic surgery has been gradually developed in recent years for thoracoscopic surgery, due to its lower rate of postoperative complications, shorter hospitalization duration, and lower invasiveness than the usual single-lung anesthesia...

The objective includes radiofrequency ablation (RFA) of a cancerous nodule results in immunogenic cell death. Tumor antigens are presented and the inflammatory environment may help stimulate adaptive and innate antitumor immunity. The objective of this study was to investigate the immune response following RFA and subsequent surgical resection in early stage non-small cell lung cancer (NSCLC). In methods, a single-session approach of computed tomography-guided tumor biopsy with immediate frozen section (and proof of NSCLC) was performed followed by RFA of the tumor in 4 patients with a solitary pulmonary nodule...

Primary pulmonary meningiomas represent a rare tumor entity. Few cases have been reported in the English medical literature, and they have almost all been solitary and benign in nature, with the exception of several extremely rare cases. We report herein a case of PPM that raised suspicion of a pulmonary metastatic tumor initially, as it was depicted as a single, round, small, ground-glass opacity pulmonary nodule on a chest computed tomography scan, in a 55-year-old man with a history of buccal cancer. Increased awareness of the clinical and radiologic characteristics of this rare category can assist a multidisciplinary team to perform adequate management...

BACKGROUND: The detection of solitary pulmonary nodules (SPNs) that may potentially develop into a malignant lesion is essential for early clinical interventions. However, grading classification based on computed tomography (CT) imaging results remains a significant challenge. The 2-[18F]-fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography (PET)/CT imaging produces both false-positive and false-negative findings for the diagnosis of SPNs. In this study, we compared 18F-FDG and 3-deoxy-3-[18F]-fluorothymidine (18F-FLT) in lung cancer PET/CT imaging...

We report an aggressive papillary thyroid carcinoma (PTC) with focal undifferentiated component in a 32-year-old female. She had limited disease confined within the thyroid gland at diagnosis. Within 12 months of thyroidectomy and radioiodine ablation, thyroglobulin (Tg) levels were elevated. Second radioiodine ablative dose was given, however, stimulated Tg levels showed an upward trend with negative iodine scan within 12 months. An 18F fludeoxyglucose-avid solitary pulmonary nodule that was detected on positron emission tomography/computed tomography scan was resected followed by empiric radioiodine therapy...

BACKGROUND AND OBJECTIVE: Dimensionality reduction techniques are developed to suppress the negative effects of high dimensional feature space of lung CT images on classification performance in computer aided detection (CAD) systems for pulmonary nodule detection. METHODS: An improved supervised locally linear embedding (SLLE) algorithm is proposed based on the concept of correlation coefficient. The Spearman's rank correlation coefficient is introduced to adjust the distance metric in the SLLE algorithm to ensure that more suitable neighborhood points could be identified, and thus to enhance the discriminating power of embedded data...
