Swelling of lymph nodes is scientifically called as Lymphadenopathy. Children are known to have swollen lymph nodes more often than adults. The swelling might be due to an infection in children, while it might be a more dangerous cause for adults. Absence of thymus is suggested a by the narrow upper mediastinum, presence of the anterior junction line in a small child, and b radiolucency of the retrosternal space in the lateral view.

Revisiting the chest for surgical clearance was not possible due to the fitness of the patient and the stormy postoperative period following the initial surgery. 12 mm for subcarinal node; 10 mm for right paratracheal node; 8 mm for others; Q2: Are you aware of the nomenclature for lymph node stations. Although careful analysis of the mediastinum on plain films is not a replacement for computed tomography of known or suspected mass lesions, it is important in detecting early or unsuspected lesions from routine chest roentgenograms. The more cephalad an upper mediastinal mass extends while still remaining visible, the more posteriorly it lies. The anterior borders of the upper lobes join immediately behind the manubrium to form the anterior junction line slightly to the left of midline. The most common lesions which cause mediastinal widening are summarized in Table 2.1 according to their usual location. 3 . 2.4) indicates that a considerable portion of the mass is in the abdomen. Mediastinal lymph node enlargement is seen on the initial chest roentgenogram in approximately 50% of patients. In an infant, pneumomediastinum may dissect the thymus from the rest of the mediastinum and elevate it like a ‘spinnaker sail.’. Mediastinal Lymphadenopathy.
