Constrictive pericarditis is a rare disease. Localized constrictive pericarditis leading to bilateral pleural effusion is more difficult to recognize, and the diagnostic procedure can be ambiguous. Here, we report two patients diagnosed with localized constrictive pericarditis who presented with bilateral pleural effusion. A thorough work-up showed that the pleural effusion was nonspecific, as was the pathology of the pleura. One patient had a history of pericardial effusion 2 years ago, and the other had undergone surgery for an anterior mediastinum teratoma. Pericardial scarring was found on their chest CT scans. The patients underwent pericardiectomy, and localized pericardial thickening was excised. The bilateral pleural effusion was effectively cured, and the patients showed satisfactory recovery on follow-up. Physicians should be aware of localized pericarditis leading to bilateral pleural effusion, and pericardiectomy is an effective diagnostic and therapeutic procedure.

BACKGROUND
Mediastinal teratoma is an uncommon disease, nevertheless they represent the most common mediastinal germ cell tumors. It may grow silently for several years and remain undiagnosed until the occurrence of a complication.
AIM
The main aim of this article is to illustrate the silent evolution of an anterior mediastinal teratoma for over 70 years without presenting any notable complications.
CASE PRESENTATION
We present the case of a 70-year-old female, treated for hypertension referred to our department for managing a voluminous mediastinal mass, discovered fortuitously by a general practitioner in a chest X-ray. The anamnesis didn't relate any chest pain, cough, dyspnea nor hemoptysis. The clinical examination, in particular pleuropulmonary, was unremarkable. The workup (Chest X-Ray and CT scan) demonstrated a voluminous pleural mass at the expense of the right mediastinal pleura, rounded in shape, with calcified wall and fluid content. Blood tests did not demonstrate eosinophilia, and hydatid IgG serology was negative. serum human chorionic gonadotropin (hCG) and alpha fetoprotein (AFP) levels were found to be normal. The patient subsequently underwent a right posterolateral thoracotomy with resection of the lesion. The mass was dissected very carefully and then resected in toto. The macroscopic and microscopic histological examination demonstrated a mature cystic teratoma. Surgical resection was an adequate treatment and the prognosis was excellent for the patient.
CONCLUSION
Cystic mature teratomas are rare thoracic tumors, often recognized by radiological examination. This article relates the silent evolution that a teratoma could have, and the late appearance of symptoms that it could have.

The CME review presented here is intended to explain the significance of pleural sonography to the interested reader and to provide information on its application. At the beginning of sonography in the 80 s of the 20th centuries, with the possible resolution of the devices at that time, the pleura could only be perceived as a white line. Due to the high impedance differences, the pleura can be delineated particularly well. With the increasing high-resolution devices of more than 10 MHz, even a normal pleura with a thickness of 0.2 mm can be assessed. This article explains the special features of the examination technique with knowledge of the pre-test probability and describes the indications for pleural sonography. Pleural sonography has a high value in emergency and intensive care medicine, preclinical, outpatient and inpatient, in the general practitioner as well as in the specialist practice of pneumologists. The special features in childhood (pediatrics) as well as in geriatrics are presented. The recognition of a pneumothorax even in difficult situations as well as the assessment of pleural effusion are explained. With the high-resolution technology, both the pleura itself and small subpleural consolidations can be assessed and used diagnostically. Both the direct and indirect sonographic signs and accompanying symptoms are described, and the concrete clinical significance of sonography is presented. The significance and criteria of conventional brightness-encoded B-scan, colour Doppler sonography (CDS) with or without spectral analysis of the Doppler signal (SDS) and contrast medium ultrasound (CEUS) are outlined. Elastography and ultrasound-guided interventions are also mentioned. A related further paper deals with the diseases of the lung parenchyma and another paper with the diseases of the thoracic wall, diaphragm and mediastinum.

OBJECTIVE
Pleural adhesions (PLAs) have been shown to be a possible risk factor for air leak after lung volume reduction surgery (LVRS), but the relevance of PLA for lung function outcome remains unclear. We analyzed our LVRS cohort for the influence of PLA on short-term (ie, prolonged air leak) and long-term outcomes.
METHODS
Retrospective observational cohort study with 187 consecutive patients who underwent LVRS from January 2016 to December 2019. PLA were defined as relevant if they were distributed extensively at the dorsal pleura; were present in at least at 2 areas, including the dorsal pleura; or present extensively at the mediastinal pleura. In patients with bilateral emphysema, bilateral LVRS was performed preferentially. The objectives were to quantify the association of PLA and rate of prolonged air leak (chest tube >7 days), and the association of PLA with postoperative exacerbations and with forced expiratory volume in 1 second 3 months postoperatively. The associations were quantified with odds ratios for binary outcomes, and with between-group differences for continuous outcomes. To account for missing observations, 100-fold multiple imputation was used.
RESULTS
PLAs were found in 46 of 187 patients (24.6%). There was a 32.6% rate of prolonged air leak (n = 61), mean chest tube time was 7.84 days. A total of 94 (50.3%) LVRSs were unilateral and 93 were bilateral. There was evidence for an association between PLA and the rate of prolonged air leak (odds ratio, 2.83; 95% CI, 1.36 to 5.89; = .006). There was no evidence for an association between PLA and postoperative exacerbations (odds ratio, 1.11; 95% CI, 0.5 to 2.45; = .79). There was no evidence for an association between PLA and forced expiratory volume in 1 second (estimate -1.52; 95% CI -5.67 to 2.63; = .47). Both unilateral and bilateral LVRS showed significant postoperative improvements in forced expiratory volume in 1 second by 27% (8.43 units; 95% CI, 3.66-13.12; = .0006) and by 28% (7.87 units; 95% CI, 4.68-11.06; < .0001) and a reduction in residual volume of 15% (-33.9 units; 95% CI, -56.37 to -11.42; = .003) and 15% (-34.9 units; 95% CI, -52.57 to -17.22; = .0001), respectively.
CONCLUSIONS
Patients should be aware of potential prolongation of hospitalization due to PLA. However, there might be no relevant influence of PLA on lung function outcomes.

BACKGROUND
To perform step-by-step analysis of the different factors (material, anesthesia technique, human, and location) that led to major pneumothorax during an infrequent pediatric cardiac MRI and to prevent its occurrence in the future. Anesthesia equipment used in a remote location is often different than those in operating rooms. For magnetic resonance imaging (MRI), ventilation devices and monitors must be compatible with the magnetic fields. During cardiac MRI numerous apneas are required and, visual contact with the patient is limited for clinical evaluation. Anesthesia-related barotrauma and pneumothorax are rare in children and the first symptoms can be masked.
CASE PRESENTATION
A 3-year-old boy with atrial septal defect (ASD) and suspicious partial anomalous pulmonary venous return was anesthetized and intubated to perform a follow up with MRI. Sevoflurane maintenance and ventilation were performed using a circular CO absorber device, co-axial circuit, and 500 mL pediatric silicone balloon. Apneas were facilitated by Alfentanyl boluses and hyperventilation. A few moderated desaturations occurred during the imaging sequences without hemodynamic changes. At the end of the MRI, facial subcutaneous emphysema was observed by swollen eyelids and crackling snow neck palpation. A complete left pneumothorax was diagnosed by auscultation, sonography examination, and chest radiograph. Pneumo-mediastinum, -pericardium and -peritoneum were present. A chest drain was placed, and the child was extubated and transferred to the pediatric intensive care unit (PICU). Despite the anesthesiologist's belief that PEEP was minimal, critical analysis revealed that PEEP was maintained at a high level throughout anesthesia. After the initial barotrauma, repeated exposure to high pressure led to the diffusion of air from the pleura to subcutaneous tissues and mediastinal and peritoneal cavities. Equipment check revealed a functional circular circuit; however, the plastic adjustable pressure-limiting valve (APL) closed within the last 30° rotation. The balloon was found to be more rigid and demonstrated significantly reduced compliance.
CONCLUSIONS
Anesthetists require proficiency is using equipment in non-OR locations and this equipment must be properly maintained and checked for malfunctions. Controlling the human factor risks by implementing checklists, formations, and alarms allows us to reduce errors. The number of pediatric anesthesia performed routinely appeared to be essential for limiting risks and reporting our mistakes will be a benefit for all who care about patients.

BACKGROUND
Tuberculosis (TB) is a very common and easily diagnosed as a malignancy. However, studies have described the difference between TB and lung cancer. Single-organ TB and lung cancer are often easily distinguished clinically. Atypical systemic hematogenous disseminated TB (HDTB) is uncommon, including rare cases involving multiple organs such as cervical lymph nodes, pleura, liver, and lung TB simultaneously, which are more confusing and easily misdiagnosed in clinical practice.
CASE PRESENTATION
A HIV-negative 56-year-old male was hospitalized for chest disease with main symptoms of chest tightness, chest pain, fatigue, anorexia, and weight loss. Heart rate 109 times/min, the computed tomography (CT) scans of the neck, chest, and abdomen revealed multiple nodules in the right pleura, right pleural encapsulated effusion, and limited, incomplete expansion of the middle and lower lobes of the right lung, enlarged lymph nodes in the right hilar and mediastinal and diaphragm groups, and multiple slightly low-density nodules in the liver, bone destruction in the 2nd thoracic vertebra, raising the possibility of multiple liver metastases of right lung cancer and malignant pleural fluid. The lymph nodes in the neck, mediastinum, abdomen, and pelvis were enlarged bilaterally. After comprehensive analysis, the patient was diagnosed with atypical systemic HDTB. After three months of conventional anti-TB treatment, the patient refused our hospital follow-up, and his symptoms improved significantly during the telephone follow-up.
CONCLUSION
Most previous TB misdiagnoses involved a single organ, and this case enriches the clinical experience of diagnosing atypical HDTB. We encourage clinicians to establish a dynamic diagnostic and therapeutic mindset, emphasizing the value of biopsy and pathology.

BACKGROUND
The incidence of critical leptospirosis manifested as massive pulmonary hemorrhage has been significantly reduced, which has been rarely reported in recent years, while the mortality rate is extremely high once it occurs.
CASE PRESENTATION
A 54-year-old man with no HIV infection was admitted to the local county hospital due to high-grade continuous fever lasting four days (38.5-40.5C), upper limb and shoulder-back muscle pain, and general fatigue. The chest CT (Aug 26, 2021) showed "multiple patchy, cloudy, and fuzzy shadows in both lungs, mainly under the pleura of the upper and lower lobes of both lungs; some lymph nodes in the mediastinum are enlarged". Despite being diagnosed with "common community-acquired pneumonia" and starting injectable levofloxacin, the symptoms worsened, and massive hemoptysis occurred. However, after being transferred to our hospital, the patient was diagnosed with the "pulmonary hemorrhage type of leptospirosis" through comprehensive dynamic analysis. The patient recovered very well after undergoing "penicillin 3MIU q6h" alone for two weeks to fight the infection.
CONCLUSIONS
Leptospirosis has a high mortality rate when it becomes critical or severe. Diagnosis typically relies on factors such as epidemiology, clinical symptoms, and pathogenetic testing. Metagenomic next-generation sequencing (mNGS) is more effective in sensitivity and speed than traditional detection methods, making it an excellent option for diagnosing challenging and severe infections in emergencies. Additionally, when experiencing sudden coughing up of blood, it's important to consider the possibility of pulmonary hemorrhage as a type of leptospirosis.

BACKGROUND
Systemic artery to pulmonary artery fistula (SA-PAF) is an uncommon disease which is often incidentally diagnosed during evaluation of hemoptysis patients. The aim of our study was to describe the cases of SA-PAF in our institution and to report the correlating clinical and radiological findings.
METHODS
We reviewed 231 chest computed tomography (CT) scans performed in our institution due to hemoptysis from January 2020 to February 2023. In patients diagnosed with SA-PAF had their electronic medical records and CT images analyzed.
RESULTS
In 231 patients, 19 (8.2%) of them had SA-PAF findings which was characterized by a peripheral nodular soft tissue opacity in the subpleural lung and traceable vascular structure in continuity with one or more peripheral pulmonary artery branches in CT. Etiology of each patient was categorized as either congenital (7, 36.8%), and acquired (12, 63.2%). The origins of SA-PAFs were 16 intercostal, two anterior mediastinal, and one costocervical artery. Eight of 19 patients did not show any associated intralobar imaging abnormalities, while bronchiectasis, cellular bronchiolitis, centrilobular emphysema, and pleura effusion were observed in 11 patients.
CONCLUSIONS
SA-PAF is a benign vascular anomaly which is frequently overlooked when evaluating hemoptysis by either clinician or radiologists but is an important factor in the differential diagnosis of patients with hemoptysis.

BACKGROUND
To evaluate the effect of tract embolization (TE) with gelatin sponge slurries during a percutaneous lung biopsy on chest tube placement and to evaluate the predictive factors of chest tube placement.
METHODS
Percutaneous CT-guided lung biopsies performed with (TE) or without (non-TE) tract embolization or between June 2012 and December 2021 at three referral tertiary centers were retrospectively analyzed. The exclusion criteria were mediastinal biopsies, pleural tumors, and tumors adjacent to the pleura without pleural crossing. Variables related to patients, tumors, and procedures were collected. Univariable and multivariable analyses were performed to determine risk factors for chest tube placement. Furthermore, the propensity score matching analysis was adopted to yield a matched cohort.
RESULTS
A total of 1157 procedures in 1157 patients were analyzed, among which 560 (48.4%) were with TE (mean age 66.5 ± 9.2, 584 men). The rates of pneumothorax (44.9% vs. 26.1%, respectively; p < 0.001) and chest tube placement (4.8% vs. 2.3%, respectively; p < 0.001) were significantly higher in the non-TE group than in the TE group. No non-targeted embolization or systemic air embolism occurred. In the whole population, two protective factors for chest tube placement were found in univariate analysis: TE (OR 0.465 [0.239-0.904], p < 0.05) and prone position (OR 0.212 [0.094-0.482], p < 0.001). These data were confirmed in multivariate analysis (p < 0.001 and p < 0.0001 respectively). In the propensity matched cohort, TE reduces significatively the risk of chest tube insertion (OR = 0.44 [0.21-0.87], p < 0.05).
CONCLUSIONS
The TE technique using standardized gelatin sponge slurry reduces the need for chest tube placement after percutaneous CT-guided lung biopsy.
CRITICAL RELEVANCE STATEMENT
The tract embolization technique using standardized gelatin sponge slurry reduces the need for chest tube placement after percutaneous CT-guided lung biopsy.
KEY POINTS
1. Use of tract embolization with gelatine sponge slurry during percutaneous lung biopsy is safe. 2. Use of tract embolization significantly reduces the risk of chest tube insertion. 3. This is the first multicenter study to show the protective effect of tract embolization on chest tube insertion.
