Abstract:
Lung cancer is one of the leading causes of death worldwide. Pulmonary nodules located in the vicinity of the mediastinum, retrocardiac, near the aorta or pulmonary vessels, and in front of the spine, may be difficult to access through a percutaneous or bronchoscopic approach. Fine needle aspiration/biopsy guided by transesophageal echoendoscopy (EUS-FNA/FNB) is a minimally invasive method with low morbidity that could allow access to lesions in these places. We present the case of a patient with a solitary pulmonary nodule, in which the diagnosis of lung cancer was obtained by EUS-FNA/FNB.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
