BACKGROUND: It is well known that ultrasound-guided needle-aspiration (USGNA) for intrapulmonary subpleural lesion in contact with the pleura is useful and safe, and its diagnostic yield is high. However, reports concerned with the analyses of cases with intrapulmonary subpleural lesion which could not be diagnosed using USGNA are limited. The objective of this study is to clarify the radiological properties of subpleural primary lung cancer which obstruct diagnosis by USGNA. METHODS: The consecutive cases with subpleural primary lung cancer whose radiological properties could be confirmed by thoracic computed tomography (CT) without contrast enhancement (CE), and examined by USGNA at our hospital between January 1999 and December 2014 have been analyzed...

Background: To find small pulmonary nodules or ground grass nodules (GGNs) with video-assisted thoracoscopic surgery (VATS) is very difficult. There are several conventional methods to localize small nodules or GGNs, which require additional radiation exposure and may cause some complications such as pneumothorax or hemothorax. We aimed to evaluate the effectiveness and feasibility of electromagnetic navigational bronchoscopy-guided pulmonary localization in a minimally invasive thoracic surgery field...

INTRODUCTION: Endometriosis is a pathological, benign, inflammatory condition characterized by the presence of endometrial glands and stroma outside the uterine cavity, typically in the pelvis. In rare conditions, this estrogen-dependent disease may be extrapelvic, presenting with a variety of symptoms, including Thoracic Endometriosis. METHODS: A 37 year-old woman presented with her third right hydropneumothorax in three months. Her medical history included infertility, an ovarian mass (in study), biliary diskinesia and protein C deficiency...

INTRODUCTION: Performing a routine postoperative chest X-ray (CXR) after general thoracic surgery is daily practice in many thoracic surgery departments. The quality, frequency of pathological findings and the clinical consequences have not been well evaluated. Furthermore, exposure to ionising radiation should be restricted to a minimum and therefore routine practice can be questioned. METHODS: As a hospital standard, each patient was given a routine CXR after opening of the pleura and inserting a chest tube...

BACKGROUND: Congenital rib abnormalities are found in approximately 2% of the general population. Usually, they occur in isolation, when they are rarely symptomatic, but they can also associate with other malformations. MATERIALS AND METHODS: We reviewed imaging examinations performed over a period of two years (2014-2015), enabling us to identify isolated rib abnormalities in six adult patients. RESULTS: The case series consisted in three cases with bilateral cervical ribs and one case each with bifid rib, costal fusion and rib pseudarthrosis...

The extrapleural space (EPS) is an anatomic space at the periphery of the chest that can be involved in a number of disease processes. This space lies between the inner surface of the ribs and the parietal pleura and contains adipose tissue, loose connective tissue, lymph nodes, vessels, endothoracic fascia, and the innermost intercostal muscle. It is often overlooked on cross-sectional imaging studies and almost invariably overlooked on conventional radiographic studies. At conventional radiography, the EPS occasionally can be seen when there is extrapleural fat proliferation, which might be confused with pleural thickening or pleural effusion...

A distinct subset of thoracic sarcomas with undifferentiated rhabdoid morphology and SMARCA4 inactivation has recently been described, and potential targeted therapy for SMARC-deficient tumors is emerging. We sought to validate the clinicopathological features of SMARCA4-deficient thoracic sarcomas. Clinicopathological information was gathered for 40 undifferentiated thoracic tumors with rhabdoid morphology (mediastinum (n=18), lung (n=14), pleura (n=8)). Thymic carcinomas (n=11) were used as a comparison group...

BACKGROUND: Unhooking or displacement of hookwire or microcoil due to technical failures is rather common. We aim to establish a new technique for remedial localization in the case of displacement or unhooking of primary mechanical localization during lung surgery. METHODS: From February 2014 to September 2015, 18 consecutive cases of intraoperative dislodgement during video-assisted thoracoscopic surgery (VATS) were enrolled. Nodule's projection on body surface was located by analyzing computed tomography (CT) images, and a needle was inserted into thoracic cavity through this point...

INTRODUCTION: The presence of endometrial tissue in airways, pleura and lung parenchyma is called thoracic endometriosis syndrome (TES). It is a rare pathology, and typically consists of catamenial pneumothorax, haemothorax, haemoptysis, and pulmonary nodules. We report a case of a 36-year-old woman with thoracic endometriosis causing catamenial haemothorax. CONCLUSIONS: The diagnosis of thoracic endometriosis is complicated and often delayed. TES should be suspected in a reproductive age woman with exacerbating symptoms during the menstruation...

Purpose  Lung Ultrasound Score (LUSS) is a useful tool for lung aeration assessment but presents two theoretical limitations. First, standard LUSS is based on longitudinal scan and detection of number/coalescence of B lines. In the longitudinal scan pleura visualization is limited by intercostal space width. Moreover, coalescence of B lines to define severe loss of aeration is not suitable for non-homogeneous lung pathologies where focal coalescence is possible. We therefore compared longitudinal vs. transversal scan and also cLUSS (standard coalescence-based LUSS) vs...

BACKGROUND: The use of video-assisted thoracoscopic surgery (VATS) has substantially increased in recent years. These procedures involve the insertion of specialized devices into the thoracic cavity via access ports. However, conventional devices such as cotton-tipped applicators and graspers can limit the field of view and injure the fragile lung tissue. The aim of this study was to develop a novel lung-stabilizing device for VATS that provides a good surgical field of view without causing lung injury...

Thymoma is an epithelial neoplasm of the thymus. It commonly lies in the anterior mediastinum and represents 20-30% of mediastinal tumours in adults. In this report we present a case of giant thymoma locating in the anterior-inferior mediastinum. A 46-year-old male came to our institute with slight pectoralgia and dyspnea. Chest CT shows a giant tumor measuring 19 cm × 16 cm × 15 cm in the left thoracic cavity. After careful examination, we performed surgery. At surgery, we found the tumor was adherent to left upper lobe of the lung, mediastinal pleura, and parietal pleural...
