hydatid cyst (hc) is a parasitic disease that may involve many organs, especially the lung and the liver. pulmonary artery location of the hydatid cyst is extremely rare, but it may cause life-threatening complications. we report a case of a hydatid cyst that completely filled the left main pulmonary artery and its distal part without cardiac involvement. thoracic computed tomography showed fil...

OBJECTIVE Endobronchial ultrasound-guided transbronchial needle aspiration could be performed better with computer-based preparation. METHODS Three-dimensional virtual bronchoscopy was used to develop 2 modes of computer-based "virtual endobronchial ultrasound." "Virtual endobronchial ultrasound standard" used conventional virtual bronchoscopy to determine the spot and angle for transbronchia...

OBJECTIVE Endobronchial ultrasound elastography is a new technique for describing the stiffness of tissue during endobronchial ultrasound-guided transbronchial needle aspiration. The aims of this study were to evaluate the utility of endobronchial ultrasound elastography for mediastinal and hilar lymph nodes, and to compare the elastographic patterns of lymph nodes with results from endobronchi...

OBJECTIVE Endobronchial ultrasound-guided transbronchial needle aspiration is of diagnostic value in hilar/mediastinal (N1/N2) lymph node staging. We assessed the utility of endobronchial ultrasound-guided transbronchial needle aspiration in lung cancer patients with N1/N2 lymph nodes detected on (18)F-fluorodeoxyglucose positron emission tomography/computed tomography. METHODS Fifty lung can...

A 47-year-old woman was referred to our hospital for further examination of a lung tumor. CT of the chest revealed a round, well-defined 2.4-cm nodule in S2, adjacent to right superior lobe bronchus. Endobronchial ultrasonography showed a well-defined, hypoechoic tumor with echogenic capsule and posterior acoustic enhancement. Diagnosis of schwannoma was confirmed from the specimen obtained by ...

OBJECTIVE Mediastinoscopy as diagnostic procedure for evaluation of mediastinum in patients with non-small-cell lung cancer has long been considered the reference standard. However, less invasive method has occurred. Endobronchial ultrasound-guided transbronchial needle aspiration came into widespread use and has resulted in controversy as to whether it is a good replacement for mediastinoscopy...

BACKGROUND Standard instructions for biopsy using the convex curvilinear endobronchial ultrasound scope include visualization and adjustment of the sheath housing the biopsy needle before every puncture. In our practice, we pre-set this relationship before inserting the endobronchial ultrasound scope and leave it fixed for every puncture. OBJECTIVE We postulated that this approach is more eff...

We present the case of an 84-year-old man with nonmassive hemoptysis and an obstructing endobronchial mass who was referred for rigid bronchoscopy and biopsy of the lesion. We illustrate how the pulsatile movement of his endobronchial lesion could be differentiated by convex probe endobronchial ultrasound bronchoscopy to be a vascular lesion rather than an endobronchial mass or tumor. Although ...
