Rheumatoid pleurisy is common in patients with rheumatoid arthritis, but distinguishing it from other diseases, such as heart failure and tuberculous pleurisy, is often difficult. A man in his 70s with stable rheumatoid arthritis presented with cardiac enlargement and bilateral pleural effusion on chest radiography. Pleural fluid studies showed lymphocytosis, adenosine deaminase level of 51.6 U/L and rheumatoid factor level of 2245.3 IU/mL, suggestive of rheumatoid pleurisy and tuberculous pleurisy. Thoracoscopy under local anaesthesia revealed erythema of the parietal pleura, small papillary projections and fibrin deposits. H&E-stained biopsy specimens showed inflammatory granulomas with strong lymphocytic infiltration and non-caseating granulomas. He was diagnosed with rheumatoid pleurisy. His symptoms improved with 30 mg of prednisolone. This study highlights that biopsy using thoracoscopy under local anaesthesia effectively diagnoses rheumatoid pleurisy, which may be challenging to diagnose.

BACKGROUND
Few studies have investigated the feasibility of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) using a free-breathing golden-angle radial stack-of-stars volume-interpolated breath-hold examination (FB radial VIBE) sequence in the lung.
PURPOSE
To investigate whether DCE-MRI using the FB radial VIBE sequence can assess morphological and kinetic parameters in patients with pulmonary lesions, with computed tomography (CT) as the reference.
MATERIAL AND METHODS
In total, 43 patients (30 men; mean age = 64 years) with one lesion each were prospectively enrolled. Morphological and kinetic features on MRI were calculated. The diagnostic performance of morphological MR features was evaluated using a receiver operating characteristic (ROC) curve. Kinetic features were compared among subgroups based on histopathological subtype, lesion size, and lymph node metastasis.
RESULTS
The maximum diameter was not significantly different between CT and MRI (3.66 ± 1.62 cm vs. 3.64 ± 1.72 cm; = 0.663). Spiculation, lobulation, cavitation or bubble-like areas of low attenuation, and lymph node enlargement had an area under the ROC curve (AUC) >0.9, while pleural indentation yielded an AUC of 0.788. The lung cancer group had significantly lower K, V, and initial AUC values than the other cause inflammation group (0.203, 0.158, and 0.589 vs. 0.597, 0.385, and 1.626; < 0.05) but significantly higher values than the tuberculosis group ( < 0.05).
CONCLUSION
Morphology features derived from FB radial VIBE have high correlations with CT, and kinetic analyses show significant differences between benign and malignant lesions. DCE-MRI with FB radial VIBE could serve as a complementary quantification tool to CT for radiation-free assessments of lung lesions.

BACKGROUND Lung cancer is the most common malignant neoplasm diagnosed worldwide. Early diagnosis and treatment are of great importance for patient's prognosis. A wide variety of pulmonary conditions display clinical and radiological presentation similar to that of lung cancer, and the awareness of their existence can help in making correct diagnoses. CASE REPORT This article presents a description of 4 patients with an insidious type of lesions mimicking pulmonary carcinomas. The first patient was referred to Department with a tumor-like lesion in the right lung. After CT of the chest and core-needle biopsy, the lesion turned out to be an ectopic thyroid tissue. The second patient reported a dry cough and weight loss. A lung nodule mass was revealed in chest CT and the patient was diagnosed with pulmonary tuberculoma. The remaining 2 patients, despite the suspicion of lung cancer, were subsequently diagnosed with a post-traumatic pleural hematoma and diffuse large B cell lymphoma. CONCLUSIONS Low-dose computed tomography of the chest plays a significant role in the diagnosis of newly detected lesions in the lungs. However, due to the similarity of the image of cancer to that of other diseases, the ultimate diagnosis should be based on the interpretation of full imaging diagnostic tests, clinical presentation, and histopathological examination of the material obtained from the lesion. Analysis of cases enables us to expand our understanding of the diseases that need to be considered in differential diagnosis of a patient with a detected tumor-like lesion in the lungs.

Tuberculosis (TB) is an airborne infectious disease caused by Mycobacterium tuberculosis (MTB). Although it typically affects the lungs (pulmonary TB), one-fifth of TB cases present as extrapulmonary TB. The diagnosis of extrapulmonary TB is often overlooked due to its atypical clinical and radiological manifestations. Differentiating TB from neoplastic conditions poses significant challenges. A 33-year-old female patient was admitted to the emergency clinic with shortness of breath, cough, and abdominal pain. Postero-anterior chest X-ray revealed massive pleural effusion leading to mediastinal shift. With a preliminary diagnosis of malignant pleural effusion, a pleural catheter was inserted, and the patient was referred for a positron emission tomography (PET/CT) to assess the primary site and the optimal location for a biopsy. The PET/CT revealed asymmetric soft tissue thickening on the left side of the nasopharynx, and increased fluorodeoxyglucose (FDG) uptake in the left cervical lymph nodes raised suspicion regarding primary nasopharyngeal cancer. Additionally, there was an increased FDG uptake observed in the mass lesion located in the right upper lobe, mediastinal lymph nodes, pleural surfaces in the left hemithorax, perihepatic areas, and peritoneum, indicating diffuse metastatic disease. Tuberculosis diagnosis was confirmed through biopsies demonstrating granulomatous inflammation in the lung and nasopharynx, along with culturing MTB from pleural effusion. Positron emission tomography played a crucial role in identifying sites of TB involvement. Despite its rarity, healthcare professionals should consider nasopharyngeal TB as a potential diagnosis when evaluating nasopharyngeal masses.

OBJECTIVE
In this study, we examined the value of chest CT signs combined with peripheral blood eosinophil percentage in differentiating between pulmonary paragonimiasis and tuberculous pleurisy in children.
METHODS
Patients with pulmonary paragonimiasis and tuberculous pleurisy were retrospectively enrolled from January 2019 to April 2023 at the Kunming Third People's Hospital and Lincang People's Hospital. There were 69 patients with pulmonary paragonimiasis (paragonimiasis group) and 89 patients with tuberculous pleurisy (tuberculosis group). Clinical symptoms, chest CT imaging findings, and laboratory test results were analyzed. Using binary logistic regression, an imaging model of CT signs and a combined model of CT signs and eosinophils were developed to calculate and compare the differential diagnostic performance of the two models.
RESULTS
CT signs were used to establish the imaging model, and the receiver operating characteristic (ROC) curve was plotted. The area under the curve (AUC) was 0.856 (95% CI: 0.799-0.913), the sensitivity was 66.7%, and the specificity was 88.9%. The combined model was established using the CT signs and eosinophil percentage, and the ROC was plotted. The AUC curve was 0.950 (95% CI: 0.919-0.980), the sensitivity was 89.9%, and the specificity was 90.1%. The differential diagnostic efficiency of the combined model was higher than that of the imaging model, and the difference in AUC was statistically significant.
CONCLUSION
The combined model has a higher differential diagnosis efficiency than the imaging model in the differentiation of pulmonary paragonimiasis and tuberculous pleurisy in children. The presence of a tunnel sign on chest CT, the absence of pulmonary nodules, and an elevated percentage of peripheral blood eosinophils are indicative of pulmonary paragonimiasis in children.

BACKGROUND
Miliary Tuberculosis (TB) remains an important infectious disease that threatens human health. The clinical characteristics and prognostic factors of miliary TB are summarized in this study.
METHODS
The clinical information of miliary TB patients between 2010 and 2022 was retrospectively analyzed. Patients with miliary TB were characterized and compared to adverse outcomes cases. Factors independently associated with adverse outcomes were determined via multivariate logistic regression analysis.
RESULTS
A total of 288 patients were analyzed, including 181 with adverse outcomes. The clinical manifestations are atypical. 88.54% Of them experienced systemic symptoms, whilst 69.79% manifested respiratory symptoms. 40.97% Presented with neurologic symptoms, while 35.07% reported gastrointestinal symptoms. The major comorbidities were pharmacological immunosuppression (21.53%), pneumoconiosis (15.28%), diabetes (10.76%), and pregnancy or postpartum (7.29%). Regarding microbiology, most patients were diagnosed via sputum or Bronchoalveolar Lavage Fluid (BALF), pleural effusion, ascites, cerebrospinal fluid, urine TB-DNA, and tuberculosis culture. Meanwhile, 2.43% of patients were diagnosed via cerebrospinal fluid NGS. Independent risk factors predictive of adverse outcomes were current smoking, leukocytosis, elevated alanine aminotransferase (ALT) levels, and the combination of lymphopenia with bone marrow tuberculosis or tuberculous lymphadenitis. The accuracy of the model was validated by an area under the ROC curve of 0.753 (95% IC 0.697-0.810).
CONCLUSIONS
The clinical manifestations of miliary TB are atypical, and early diagnosis is challenging. The major comorbidities in miliary TB patients were pharmacological immunosuppression, pneumoconiosis, diabetes, pregnancy, and postpartum. Regarding etiological detection, multi-site and multi-type specimens should be collected for a timely diagnosis. Cerebrospinal fluid mNGS test may be a viable choice in some cases. Finally, current smoking, leukocytosis, elevated ALT levels, and the combination of lymphopenia with bone marrow tuberculosis or tuberculous lymphadenitis were identified as independent risk factors for adverse outcomes.

BACKGROUND Effusive-constrictive pericarditis (ECP) is an uncommon clinical syndrome characterized by the coexistence of pericardial effusion and constriction involving the visceral pericardium. This differs from constrictive pericarditis, which presents with thickening of the pericardium without effusions. Specific diagnostic criteria of ECP include the failure of right atrial pressure to decrease by 50% or reach a new level below 10 mmHg after normalization of intrapericardial pressure. CASE REPORT We present the case of a 32-year-old obese man with multiple comorbidities who initially presented with flu-like symptoms and pleural effusion with development of constrictive-like symptoms. Despite undergoing numerous pericardiocentesis and appropriate medical management, the patient's condition failed to improve, leading to the likely diagnosis of effusive-constrictive pericarditis. Cultures of pericardial fluid revealed E. -faecium, which required multiple antimicrobial therapy. Despite infection, the exact etiology of ECP remained unknown and likely idiopathic. Common causes of ECP include idiopathic, tuberculosis, cardiac surgery complications, radiation, or neoplasia. Ultimately, the patient underwent a pericardiectomy involving the visceral and parietal pericardium, resulting in hemodynamic stability and resolution of symptoms. CONCLUSIONS This case highlights the challenges in diagnosing and managing ECP, emphasizing the importance of considering surgical intervention in refractory cases. ECP initially presents as a pericardial effusion, often addressed through pericardiocentesis; however, in a small subset of patients, sustained symptoms and altered hemodynamics persist following pericardiocentesis, necessitating further evaluation and management. The success of pericardiectomy in our patient highlights the potential efficacy of surgical intervention in improving outcomes for patients with ECP.

Tuberculosis can present at various extrapulmonary sites. However, even in endemic countries, concomitant involvement of different sites in the same patient is rarely reported. Further, tuberculous pericarditis represents a fraction of all tuberculosis infections and is an uncommon form of extrapulmonary tuberculosis. In underdeveloped nations, it is the most frequent cause of massive pericardial effusion. Additionally, it is the most common cause of constrictive pericarditis in adults, which has a high death rate and a poor prognosis. Furthermore, concomitant pleural effusion due to is infrequently reported. Herein, a case of concomitant pericardial and left-sided pleural effusion in an Indian female is reported. She came with complaints of breathlessness, chest pain, night sweats, and loss of appetite. A diagnostic pleural thoracentesis and pericardiocentesis helped establish the diagnosis, and she was commenced on antituberculous treatment for 168 days.
