Official Title: CT Enlarged Mediastinal/Hilar Lymph Nodes Not Visible on Chest X-ray in the Non Cancer Patient : Diagnosis and Clinical Implications Using Endobronchial or Esophageal Ultrasound Controlled Needle Aspi

Brief Summary: Patients are often referred for E(B)US examination and sampling of enlarged mediastinal and/or hilar lymph nodes that are not visible on a standard chest X-ray but are discovered by accident on CT scan performed outside the context of lung cancer or extrathoracic malignancies. Since CT scan is largely used and E(B)US is a minimally invasive technique, these cases are explored more frequently but so far nothing is known, however, on the prevalence of abnormal findings in EBUS sampling in this particular population and on the clinical implications (mainly therapeutical implications) of E(B)US findings.

Detailed Summary: The primary aim is to assess the nature and prevalence of abnormal findings in samplings obtained during E(B)US-NA in the non-cancer patient with CT enlarged mediastinal/hilar lymph nodes that are not visible on chest X-ray. As secondary aims, the clinical implications of E(B)US-NA findings will be assessed, in particular the number of cases where a specific treatment is initiated.
