Objective. The purpose of this study was to assess the accuracy of sonographic pneumothorax detection by radiology residents as a part of extended focused assessment with sonography for trauma (eFAST). Methods. In a prospective study, a sonographic search for pneumothoraces was performed as part of a standard FAST examination by the on‐call resident Research Article Effective Pneumothorax Detection for Chest X-Ray Images Using Local Binary Pattern and Support Vector Machine Yuan-Hao Chan,1 Yong-Zhi Zeng,2 Hsien-Chu Wu ,2,3 Ming-Chi Wu,4 and Hung-Min Sun 1,5 1Institute of Information Systems and Applications, National Tsing Hua University, Hsinchu, Taiwan 2Department of Computer Science and Information Engineering, National Taichung. Pneumothorax, sometimes abbreviated to PTX, (plural: pneumothoraces) refers to the presence of gas (often air) in the pleural space.When this collection of gas is constantly enlarging with resulting compression of mediastinal structures, it can be life-threatening and is known as a tension pneumothorax (if no tension is present it is a simple pneumothorax)
Pneumothorax Fauniel Self 10/14/2020 RAD 4001 Bosserman, Andrew, MD. McGovern Medical School Clinical History •Patient is a 36-year-old male who presented as a level 1 trauma with GSW primarily to L chest with small ballistic injuries to all extremities bilaterally •+ SOB •GCS 1 This is especially true inasmuch as diagnostic pneumothorax furnishes valuable information, is relatively safe and easy to perform, and does not aggravate the patient's condition. The technic depends on whether or not there is an associated pleural effusion. In the absence of pleural fluid, the air usually is introduced under local anesthesia. Hydropneumothorax. A hydropneumothorax (plural: hydropneumothoraces) (or less commonly pneumohydrothorax (plural: pneumohydrothoraces)) is the term given to the concurrent presence of a pneumothorax and pleural effusion (i.e. hydrothorax) (i.e. gas and fluid) in the pleural space Pneumothorax. 1.

Some use the term pulmonary bleb for a similar lesion less than 1 or 2 cm, whereas others use both the terms bleb and bulla interchangeably. They are often subpleural in location and are typically larger.
Trapped lung, also known as unexpandable / unexpanded lung , is a term used where there is non-expandable lung after fluid removal, often thoracentes i s . It is similar to but not entirely synonymous with the term lung entrapment, which is a similar condition caused by active pleural disease rather than pleural inflammation from remote disease Pneumomediastinum and spontaneous pneumothorax as an extrapulmonary complication of COVID-19 disease Jesse Mauricio López Vega1 & María Luz Parra Gordo1 & Aurea Diez Tascón1 & Silvia Ossaba Vélez1 Received: 12 May 2020 /Accepted: 8 June 2020 # American Society of Emergency Radiology 2020 Abstrac A pneumothorax (collapsed lung, dropped lung) is the entry of air into the pleural space (the space between the lungs and chest wall).. When air enters this area, the lung loses contact with the inside of the chest and drops down. As this happens, the lung is not able to expand as it usually does

Eligible patients include those with a giant bulla occupying one-fourth or more of one hemithorax on preoperative imaging. We describe in this report a valuable sign to distinguish pneumothorax from adjacent giant bullae: the double-wall sign. This sign occurs when one sees air outlining both sides of the bulla wall parallel to the chest wall. Diagnosis of a pneumothorax in the perioperative area can be difficult. Traditional gold-standard modalities may not be available or feasible to institute. Ultrasound guidance allows the anesthesia provider a method of quickly ruling out this potentially life-threatening complication. In this article we detail the use of sonography for fast and accurate diagnosis of pneumothorax Abstract. As the COVID-19 pandemic progresses, awareness of uncommon presentations of the disease increases. Such is the case with pneumothorax and pneumomediastinum. Recent evidence suggested that these can occur in the context of COVID-19 pneumonia, even in the absence of mechanical ventilation-related barotrauma. We present two patients with COVID-19 pneumonia complicated by. pneumothorax Radiology Apical, paraseptal and parenchymal lung bullae, paraseptal emphysema, apical pleural thickness, and subpleural nodules Spinal and paraspinal tumours Centrilobular emphysema, subpleural thin- walled lung cysts, bilateral basal reticular opacities, basa Three American College of Veterinary Radiology-certified veterinary radiologists blinded to surgical findings reviewed dorsal and sternal images simultaneously. Severity of pneumothorax, degree of atelectasis, lesion location and size, and view in which lesions were most confidently identified were compared to surgical and histologic findings
The pneumothorax case was a difficult judgment when pneumothorax region is extremely stenotic and close to the chest boundaries. In addition, pixels located near the chest boundaries tend to have less discriminative texture on image indication, because the bones and pleura existed in obvious edges, which reduced their correspondence of textures ESSENTIALS OF RADIOLOGY STUDY GUIDE The Essentials of Radiology Examination is designed to test the radiology knowledge and clinical skills across both the subspecialties and imaging modalities of diagnostic radiology for the imaging diagnosis of conditions that may be encountered in the practices of all radiologists Positioning patients in lateral decubitus with the biopsied lung dependent, puncture site down with a biopsy window in the CT table, using smaller calibre needles and using coaxial technique if multiple samples are needed are associated with a reduced incidence of pneumothorax
Methods Cases were collected retrospectively from UK hospitals with inclusion criteria limited to a diagnosis of COVID-19 and the presence of either pneumothorax or pneumomediastinum. Patients included in the study presented between March and June 2020. Details obtained from the medical record included demographics, radiology, laboratory investigations, clinical management and survival Coronavirus Disease 2019 (COVID-19) has rapidly spread worldwide. Numerous studies have shown its typical and atypical CT findings. We report one COVID-19 patient who presented with a transient pneumothorax, spontaneous pneumomediastinum (SP), as well as subcutaneous emphysema during hospitalization pneumothorax after thoracentesis with or without ultrasound guidance for all causes of pleural effusion. A meta-analysis of 24 studiesand6,605thoracentesespublishedin 2010 found that the overall pneumothorax risk after thoracentesis was 6.0%, and that ultrasound guidance was associated with a lower risk of pneumothorax (4.0% vs. 9.3% 41 Chest Radiology CH 2 Dyspnoea REMARKS 1 Dyspnoea can be broadly classified into cardiac or pulmonary origins. 2 Chest X-ray (CXR) usually forms part of the initial workup for patients presenting with dyspnoea. 3 In two-thirds of the cases, CXR can help to make a diagnosis. 4 For patients with asthma or chronic obstructive pulmonary disease (COPD) exacerbation Automated triage of patients in radiology is a rapidly developing machine learning application with the goal of early detection of urgent pathologies [1, 2].One such pathology is a pneumothorax, the relevance of which is reflected by its frequency and the possibility of severe complications
Patients with idiopathic pulmonary fibrosis (IPF) are at risk for a variety of acute pulmonary complications, including pneumothorax and pneumomediastinum. Our aim was to describe the radiographic and CT findings and to determine the frequency of complicating spontaneous pneumothorax and pneumomediastinum in patients with IPF.

Pneumothorax is an abnormal collection of air in the pleural space and classified as spontaneous (primary or secondary) or traumatic. Primary spontaneous pneumothorax usually occurs in the absence of underlying lung disease. Patients are classically described as tall men, aged 20 to 40 years, who are smokers Spontaneous pneumomediastinum, pneumothorax and spontaneous subcutaneous emphysema are rare entities. A rising trend in the setting of COVID-19 even in patients who are not put on invasive ventilation can suggest an alternative aetiology. We describe four cases which presented with suspected symptoms of COVID-19 and were diagnosed with pneumomediastinum, pneumothorax, and subcutaneous. Background Pneumothorax can lead to a life-threatening emergency. The experienced radiologists can offer precise diagnosis according to the chest radiographs. The localization of the pneumothorax lesions will help to quickly diagnose, which will be benefit for the patients in the underdevelopment areas lack of the experienced radiologists.

In a study of 4,262 consecutive lung biopsies, the overall rate of pneumothorax and chest tube placement was 30.2% and 15%, respectively . The rate of pneumothorax and chest tube placement was lower with the use of a 19 gauge guide needle (24.5% and 13.1%, respectively) when compared to 18 gauge guide needle (35% and 16.7%, respectively) The bedside chest x-ray (CXR) is an indispensible diagnostic tool for monitoring seriously ill patients in the intensive care unit. The CXR often reveals abnormalities that may not be detected clinically. In addition, bedside CXRs are an irreplaceable tool with which to detect the malposition of tubes and lines and to identify associated complications. Although the image quality is often. A chest radiograph showed a large right pneumothorax along with a smaller left pneumothorax, pneumomediastinum, and subcutaneous emphysema. Bilateral chest tubes were placed. A subsequent radiograph showed bilateral lung re-expansion but with a right-sided ovoid lucency measuring 11.3 x 5 cm suggestive of a pneumatocele (Figure 1C). Extensive. Pneumothorax often complicates the management of mechanically ventilated severe acute respiratory syndrome (SARS) patients in the isolation intensive care unit (ICU). We sought to determine whether pneumothoraces are induced by high ventilatory pressure or volume and if they are associated with mortality in mechanically ventilated SARS patients Benign pleural thickening caused by fibrosis is the second most common pleural abnormality, the most common one being effusion. Pleural fibrosis has a number of causes and is the outcome of many pleural diseases and a potential complication of every inflammatory condition that affects the lungs. The pleura show a variety of patterns of fibrosis

Pneumothorax or hemothorax may also be identified by placing the probe along the chest wall and looking for the presence of lung sliding. Loss of sliding implies the possible presence of a pneumothorax. 10. Radiology: Imaging Trauma Patients in Deployed Setting, 13 Mar 2017. Abnormal. An apical pneumothorax is present on the right side. Diagnosis: Spontaneous Pneumothorax. Note: the difference between the apices of the right and left lungs. Specifically (1) the visceral pleural line is just visible at the right apex, and (2) the absence of any lung markings lateral to this visceral pleural line A primary spontaneous pneumothorax occurs in young people without known respiratory illnesses. A secondary spontaneous pneumothorax occurs in patients with pre-existing pulmonary diseases.A tension pneumothorax is a medical emergency that requires immediate decompression.Patients with a pneumothorax Pneumothorax is the medical term for a collapsed lung. This occurs when air is trapped in the space around the lungs. A collapsed lung can result in your chest feeling tight and achy and make it. SP, pneumothorax and subcutaneous emphysema are extremely rare in COVID-19. The probable cause of SP in COVID-19 in the reported case was alveolar damage. SP and pneumothorax may be related to death when SP and pneumothorax are found, and the patient should be carefully monitored to prevent respiratory deterioration
When interpreting a chest X-ray you should divide each of the lungs into three zones, each occupying one-third of the height of the lung. These zones do not equate to lung lobes (e.g. the left lung has three zones but only two lobes). Inspect the lung zones ensuring that lung markings are present throughout clamp the distal end; if there is a pneumothorax, bubbling may be seen. If there is a large pleural effusion, it will begin collecting. Do not reclamp the chest tube, once released, unless the pleural drainage system is being changed. Reclamping the tube may lead to the redevelopment of a pneumothorax and may create a tension pneumothorax Pneumothorax is a recognized cause of preventable death following chest wall trauma where a simple intervention can be life saving. In cases of trauma patients where cervical spine immobilization is mandatory, supine AP chest radiograph is the most practical initial study. It is however not as sensitive as CT chest for early detection of a pneumothorax Tension pneumothorax as the cause of death may be missed, unless post mortem examination includes chest radiology or monitors pleural pressure before opening the thoracic cavity (84,85). This raises the question as to whether any asthma deaths may be due to tension pneumothorax and if they could have been prevented
Pneumothorax is defined as the presence of air or gas in the pleural cavity (ie, the potential space between the visceral and parietal pleura of the lung). The clinical results are dependent on the degree of collapse of the lung on the affected side. Pneumothorax can impair oxygenation and/or ventilation Determining the size of pneumothorax in the upright patient.Radiology 1982:144:733-736). Both studies compare the size of the lung in relation to the size of the thorax with labels B and C referring to the interpleural distance at the mid points of the upper and lower hemithoraces respectively, not the midpoints of the collapsed lungs, as used.
Tension pneumothorax is a life-threatening condition that can occur with chest trauma when air is trapped in the pleural cavity leading to a cascading impact including a rapid deterioration of a patient's ability to maintain oxygenation. Tension pneumothorax is more likely to occur with trauma involving an opening in the chest wall Clinical features of a pneumothorax. A pneumothorax is a collection of air between the parietal and visceral pleura of the lung.There are several different ways to classify and name pneumothoraces. Pneumothoracies can be classified as either primary or secondary:. A primary pneumothorax develops in the absence of an underlying disease process.; A secondary pneumothorax develops as a result of. Lung transplant patients commonly undergo transbronchial biopsy to evaluate for rejection. Post-biopsy radiographs are used to exclude pneumothorax, one of the most common major complications. We report a lung transplant patient who developed a pneumothorax 5 months after transbronchial biopsy, with multiple intervening chest computed tomograms documenting that the pneumothorax developed from.
