EBUS-TBNA was performed to puncture the subcarinal
lymph node (#7) on August 17, 2016.
Bronchogenic cysts are typically located in the precarinal and subcarinal
regions (Figure 12) but may occur in any part of the mediastinum and even be intrapulmonary (20%).
We completed positron emission and computed tomography scans by using intravenous F-18 fluoro-2-deoxyglucose that detected hypermetabolic foci in the right axilla, subpectoral, subcarinal
, and para hilar regions.
Furthermore, conventional TBNA and EBUS-TBNA have comparable diagnostic accuracy in puncture sampling of mediastinum 4R, subcarinal
group, and large lymph nodes (17,18).
29,34] Computed tomography (CT) may reveal the enlargement of left paratracheal' paraaortic' and subcarinal
lymph node groups also.
Infection of the subcarinal
, paratracheal and parabronchial lymph nodes is thought to result in caseative necrosis and abscess formation with eventual rupture into the oesophagus and trachea.
A thoracic computer tomography revealed bilateral hilar, subcarinal
, and aortopulmonary lymphadenopathies as well as perilymphatic and peribronchovascular nodules in both lungs.
Lymphadenopathies at both hiluses (arrows) and subcarinal
Multiple marginally enlarged lymph nodes were noted at pretracheal, right paratracheal, subcarinal
region and at aortopulmonary window; but once again, the aetiology of SVC syndrome remained undiagnosed as no lymph node or mass was found to compress SVC.
Se hace tomografia de torax simple de control que muestra aumento de la neumonia con signos de hepatizacion, tiene aspecto de masa, adenopatias en hilio izquierdo, conglomerado subcarinal
importante, ganglios perivasculares y minimo derrame pleural.

In determining the lymph node involvement in cases of NSCLC, EBUS-guided transbronchial needle aspiration (TBNA) has a much better diagnostic yield as compared to conventional TBNA in all lymph node stations except the subcarinal
