The lymph nodes in the mediastinum. The "normal" size of a lymph node varies based off of where it is. We studied 40 adult cadavers and determined the number and size of normal lymph nodes for each region of the mediastinum, counting all nodes and directly measuring the short and long diameters of each in the transverse plane of the node. Patients with peripheral tumors smaller than 2 cm and a normal mediastinum were ineligible. A PET/CT nomogram incorporating SUVmax and CT radiomics for preoperative nodal staging in non-small cell lung cancer. Establishment of an upper limit for node size by specific location, analogous to that which has been reported for mediastinal lymph nodes, was sought. As many diseases cause the lymph nodes in the chest to be enlarged and there is no certain way of knowing which disease is causing them to be enlarged doctors often require a small sample (biopsy) from the lymph nodes to make a clear diagnosis. Findings for 56 patients show the largest normal mediastinal nodes to be in the subcarinal and right tracheobronchial regions. 2021 Aug 19;12(1):5045. doi: 10.1038/s41467-021-25188-0. doi: 10.1097/MD.0000000000026897.
