Measuring the short-axis diameter is better than measuring the long-axis or greatest diameter because it more closely reflects the actual node diameter when nodes are obliquely oriented relative to the scan plane and shows less variation among healthy individuals. These regions are where the lymphatics are extensive, and this pattern is termed a perilymphatic distribution (2).

Statement on sarcoidosis. abuts 2R, inferior border: superior border of the left main pulmonary artery, lymph nodes anterior to the tracheal bifurcation are inferior to the above anatomic definitions and are thus technically unclassified by IASLC, these nodes are in the mediastinum (N2) and their surgical management mirrors that of 4R/4L lymph nodes, hence, pre-carinal nodes are best classified as part of the 4R/4L stations, superior border: inferior border of the aortic arch, superior border: line tangential to the upper border of the aortic arch, inferior border: lower border of the aortic arch, superior border: station 7, i.e. This type progresses fairly rapidly without treatment. Answer (1 of 3): Shotty lymph nodes are clusters of small, swollen lymph nodes suggesting reaction to an infection. They drain the posterior chest wall and pleura. PET has a sensitivity of about 80% for diagnosis of mediastinal node metastases (vs. 60% for CT) and a specificity of about 90% (compared with 70% for CT). They are commonly seen in patients with active tuberculosis, fungal infections, and neoplasms, such as metastatic carcinoma and lymphoma. Winterbauer RH, Lammert J, Selland M et al.

Also, an irregular lesion in the posterior right upper lobe measuring currently 1.2 x 3.0 cm. Paratracheal lymph nodes The right and left paratracheal lymph nodes (or paratracheal chains) are groups of lymph nodes located in the throat . Several numerical systems have been proposed for identifying the specific locations of intrathoracic lymph nodes (i.e., lymph node stations ), primarily for the purpose of lung cancer staging. Small lymph nodes are visible in the aortopulmonary window, Upper Limits of Normal for the Short-Axis Node Diameter. Diagnosis of unknown sarcoidosis associated to erythema nodosum with 18 IT IS IN THE CARNIA, HILUM,PARATRACHEAL NODE AND SUPERIOR MEDIASTINUM. Positron emission tomography (PET) is more accurate than CT in the assessment of mediastinal lymph node metastases in lung cancer and has assumed a significant role in preoperative staging.
