Background Video-assisted thoracic surgery (VATS) is widely used for thoracic surgery operations, and day by day it becomes routine for the excision of undetermined pulmonary nodules. However, it is sometimes hard to reach millimetric nodules through a VATS incision. Therefore, some additional techniques were developed to reach such nodules little in size and which are settled on a challenging localization. In the literature, coils, hook wires, methylene blue, lipidol, and barium staining, and also ultrasound guidance were described for this aim...

PURPOSE: Efficient monitoring of tumor responsiveness to chemotherapy is essential to mitigate high mortality risks and cytotoxic effects of chemotherapeutics. However, there is no consensus on the most suitable diagnostic technique/parameters for assessing response to chemotherapy in malignant pleural mesothelioma (MPM). We compared the tumor responsiveness of MPM patients as assessed using modified RECIST (mRECIST) criteria and integrated 18F-FDG-PET/CT. METHODS: Histologically confirmed MPM patients (N=82) who were treated with three cycles of cisplatin and pemetrexed, or carboplatin and pemetrexed, were included...

BACKGROUND: The management of graft infection following ascending aortic replacement (AAR) and/or aortic valve replacement (AVR) with destruction of the root remains a challenge. Besides technical issues, the choice of graft material is controversial. The study aim was to investigate the initial results of aortic root replacement (ARR) as redo-surgery for infection using the xenopericardial all-biologic conduit (BioIntegral) as an alternative to a homograft or prosthetic material. METHODS: Between February 2013 and January 2015, a total of 18 consecutive patients (16 males, two females; mean age 61 ± 14 years) were reoperated on for infection at a mean of 55 ± 61 months (range: 3 to 219 months) following previous AVR (n = 6), supracoronary aortic replacement (SAR, n = 2), AVR + SAR (n = 1), root replacement (n = 7), and root reconstruction (n = 2)...

A 68-year-old man was referred to our hospital because of an abnormal shadow in the chest roentgenogram. Chest computed tomography (CT) showed the nodule in the right upper lobe (S3), 17 mm in size. One month later, fluorodeoxyglucose-positron emission tomography (FDG-PET)/CT scanning revealed positive reaction in the right upper lobe lesion and new lesion close to another lobe. In addition, interloblar small nodules were detected, 5 mm and 7 mm in size. A transbronchial brush cytology by bronchoscopy was performed, and the microscopic findings demonstrated the presence of atypical cells, suspected adenocarcinoma...

The aim of this study was to evaluate the relationship of the pre-treatment blood neutrophil/lymphocyte count ratio (NLR) with the maximum standard uptake value (SUVmax) of primary masses on positron emission tomography/computed tomography (PET/CT) taken before treatment in patients diagnosed with malignant pleural mesothelioma (MPM) and to evaluate the contribution to prognosis. A retrospective evaluation was made of 73 patients diagnosed with MPM in our hospital between January 2006 and January 2014. The SUVmax value of the primary mass on pre-treatment PET/CT, the haemogram parameters (Hb, Hct, NLR, MPV, PLT) at the time of diagnosis, the progression history, the date of the final visit and the date of death of exitus patients was recorted from patient files PET/CT...

BACKGROUND: The gross tumor volume (GTV) definition for malignant pleural mesothelioma (MPM) is ill-defined. We therefore investigated which imaging modality is optimal: computed tomography (CT) with intravenous contrast (IVC), positron emission tomography-CT (PET/CT) or magnetic resonance imaging (MRI). MATERIAL AND METHODS: Sixteen consecutive patients with untreated stage I-IV MPM were included. Patients with prior pleurodesis were excluded. CT with IVC, 18FDG-PET/CT and MRI (T2 and contrast-enhanced T1) were obtained...

Mesothelioma is an uncommon malignant neoplasm and a localised form of the pleura is especially very rare. Diagnosis of localised malignant pleural mesothelioma (LMPM) is very challenging. Histopathological verification is the gold standard, and studies such as CT, positron emission tomography (PET) and thoracoscopy are very valuable tools in assisting diagnosis. We report a case of histopathologically proven LMPM, which was discovered as a well circumscribed solitary subpleural nodule on PET-CT after presentation with cranial metastasis...

Mesothelioma is a rare pulmonary malignancy commonly associated with asbestos exposure. Its presentation is insidious and non-specific, with complaints of chest pain, dyspnea and cough. Chest X-ray may demonstrate unilateral pleural effusion. CT and PET scans may highlight nodular pleural plaques. Diagnosis often times is difficult with negative imaging and negative pleural fluid studies. In rare cases, hydropneumothoraces may be seen. We report a case of malignant pleural mesothelioma presenting as recurrent hydropneumothorax with negative CT scan of the chest for pleural abnormalities and negative pleural fluid studies...

BACKGROUND: Lymph nodes in patients with non-small cell lung cancer (NSCLC) are often staged using integrated 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT). However, this modality has limited ability to detect micrometastases. We aimed to define risk factors for occult lymph node metastasis in patients with clinical stage I NSCLC diagnosed by preoperative integrated FDG-PET/CT. METHODS: We retrospectively reviewed the records of 246 patients diagnosed with clinical stage I NSCLC based on integrated FDG-PET/CT between April 2007 and May 2015...

Immunoglobulin G4-related disease (IgG4-RD) is a chronic disease that presents with inflammation and fibrosis of involved tissue. It encompasses several disorders previously described using different terms, but all disorders are characterised by IgG4-positive plasma cells and lymphocytes infiltration of tissues. We report a rare case of a 58-year-old man with IgG4-related pleural disease without other systemic manifestations. The diagnosis was based on characteristic changes on PET-CT and typical histopathology in a pleural specimen...

A 72-year-old man presented with fever, dyspnea, and weight loss. He was referred to our hospital for further examination of the cause of the pleural effusions. Chest computed tomography showed pleural effusions, a pericardial effusion, and enlarged lymph nodes in the carina tracheae. We administered treatment for heart failure and conducted analyses for a malignant tumor. The pericardial effusion improved, but the pericardium was thickened. Positron emission tomography-computed tomography (PET-CT) showed fluorine-18 deoxyglucose accumulation at the superior fovea of the right clavicle, carina tracheae, superior mediastinum lymph nodes, and a thickened pericardium...
