Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has been widely used for diagnosing intrathoracic lymphadenopathy. Here, we present two cases of endobronchial polyp formation after an EBUS-TBNA for suspicious malignant lymph nodes. An inflammatory polyp should be considered as a possible differential diagnosis for a newly developed mass after an EBUS-TBNA.

Endobronchial ultrasound has become the first choice standard of care procedure to diagnose benign or malignant lesions involving mediastinum and lung parenchyma adjacent to the airways owing to its characteristics of being real-time and minimally invasive. Although the incidence of lung cancer has been decreasing, it is and will be the leading cause of cancer-related mortality in the next few ...

Endobronchial ultrasound (EBUS) has emerged as a new diagnostic tool that allows the bronchoscopist to see beyond the airway. The radial probe EBUS was first introduced to evaluate the airway structure, which has been shown to be useful for identifying the extent of tumor invasion in the central airway. The newest development is the convex EBUS-TBNA scope with a curvilinear electronic transduce...

A 61-year-old woman came to the hospital with dyspnea and pleural effusion on chest radiography. She underwent repeated thoracentesis, transbronchial lung biopsy, bronchoalveolar lavage, and thoracoscopic pleural biopsy with talc pleurodesis, but diagnosis of her was uncertain. Positron emission tomography showed multiple lymphadenopathies, so she underwent endobronchial ultrasound-guided trans...

The development of a convex probe endobronchial ultrasound (CP-EBUS) videobronchoscope to allow real-time transbronchial needle aspiration (TBNA) has been a significant advance in minimally invasive lung cancer staging and diagnosis. Several recent studies have demonstrated CP-EBUS-TBNA to have recovery rivalling that of the current gold standard, cervical mediastinoscopy. These same studies ha...

A 45-year-old Japanese woman complained of uncontrolled hypertension and face swelling. She was diagnosed with Cushing's syndrome with secretion of adrenocorticotropic hormone. Fluorodeoxyglucose positron emission tomography-computed tomography revealed a 2 × 2 cm mass in her left lung, with high standardized maximum uptake value. She underwent bronchoscopy with endobronchial ultrasound via a g...

Radiation therapy has emerged as a useful alternative therapy for patients with early-stage, non-resectable lung cancer. In patients whose malignancies are difficult to localize on computed tomography imaging, such therapy becomes difficult. Fiducial markers are frequently placed in peripheral pulmonary lesions to assist radiation therapy. Although placement of markers under linear endobronchia...

Background: This study aimed to investigate the value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) guided purulence and local isoniazid injection after lymph node puncture in treatment refractory mediastinal tuberculous lymphadenitis (MTLA) as compared systemic anti-tuberculosis treatment.
