Inflammatory endobronchial polyp is a rare disease mostly encountered in asthmatic patients. Chronic airway and foreign material irritation or thermal injury may result in the formation of granulated tissues and become polypoid mass. Herein, we describe a 52-year-old man with severe respiratory distress and infection with 35 years history of smoking. He had an obstructive pattern in his pulmona...

Pulmonary embolism (PE) is a life-threatening condition with varied presentation and, therefore, poses clinical challenge for early diagnosis and proper management without which it carries high mortality. Previous studies on the role of endobronchial ultrasound (EBUS) in diagnosis of PE were carried out after PE was already diagnosed by computed tomography pulmonary angiography. We report a cas...

State-of-the-art practice for lung-cancer staging bronchoscopy often draws upon a combination of endobronchial ultrasound (EBUS) and multidetector computed-tomography (MDCT) imaging. While EBUS offers real-time in vivo imaging of suspicious lesions and lymph nodes, its low signal-to-noise ratio and tendency to exhibit missing region-of-interest (ROI) boundaries complicate diagnostic tasks. Furt...

In the last years, several techniques have been developed to obtain a prompt diagnosis or rule out lung cancer. Endobronchial ultrasound- guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive procedure with a high diagnostic yield for mediastinal and central pulmonary lesions. This procedure is especially useful for lung cancer diagnosis and mediastinal staging. Two differ...

Accurate staging is the first step in the management of lung cancer. Nodal staging is quite important for physicians to be able to judge the primary operability of patients harboring no distant metastasis. For many years, mediastinoscopy has been considered a "gold standard" modality for nodal staging. Mediastinoscopy is known to be a highly sensitive procedure for mediastinal staging and has b...

In a recent issue of CHEST (January 2011), Gounant et al 1 showed that dedicated linear echoendoscope endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) needles are able to release metal particles, probably by friction between the stylet and the needle, with a potential risk of injecting particles into nodes. After reading this article, we are a bit confused for severa...

BACKGROUND In lung cancer patients, the adrenal glands are predilection sites for distant metastases. Esophageal endoscopic ultrasound - fine-needle aspiration (EUS-FNA) is a minimally invasive and accurate method for left adrenal gland (LAG) analysis but requires a conventional gastrointestinal echoendoscope. Complete endobronchial and esophageal mediastinal nodal staging can be achieved by ju...
