Abstract
Pulmonary lesions with wall contact represent a frequent pathology that requires complex imaging studies, and often interventional procedures, in order to reach the complete diagnosis. In most cases, after a pulmonary lesion is found on a thoracic radiograph,the next step is to perform a bronchoscope and/or a Computed Tomography (CT). But peripheral pulmonary lesions often call for additional investigations. Transthoracic ultrasonography (TUS) permits visualization of these lesions, their structural characterization, while offering suggestive elements for their malignant nature and for the differential diagnosis. Furthermore ultrasound allows percutaneous guided biopsies with lower risks compared with the other radiological guiding methods (fluoroscopy and CT). Ultarsound advantages are numerous;accesibility (including bedside examination), lower costs, no radiation exposure, and shorter biopsy time. In the present study we aimed to evaluate the role of ultrasound guided transthoracic fine needle aspiration and core needle biopsy in the diagnosis of peripheral pulmonary lesions.
