Precarinal lymph nodes are located in the precarinal area, which is within the chest cavity around the lungs. For patients with lymph nodes measuring 16 mm on CT and a negative FDG-PET result a post-test probability for N2 disease of 21% was found, suggesting that these patients should be planned for mediastinoscopy prior to possible thoracotomy to prevent too many unnecessary thoracotomies in this subset.

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. Invasions of the diaphragm, mediastinum, heart, great vessels, trachea, carina, esophagus, recurrent laryngeal nerve, or vertebral body are termed T4 , and in the absence of mediastinal lymph node metastases are classified as stage IIIA.

The short-axis or least diameter (i.e., the smallest node diameter seen in cross section) is generally used when one is measuring the size of a lymph node. Different values for the upper limits of normal short-axis node diameter have been found for different mediastinal node groups ( Table 4.2 ). The location of precarinal lymph nodes in the body is the pericardial space. Dr. Arun Phophalia. The lymphatic system includes the lymph nodes (lymph glands), spleen, thymus gland and bone marrow.

As sarcoidosis is an inflammatory disease, false-positives on PET are often seen and a misdiagnosis of cancer made (15,16). One of the first attempted links between sarcoidosis and malignancy was a paper by Brincker in 1974 (5). Pretracheal or paratracheal nodes occupy the pretracheal (or anterior paratracheal) space ( Figs. 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). 4.7 ). In the absence of a known disease, an enlarged node must be regarded as likely hyperplastic or reactive. Pathologic lymph nodes with an increased vascular supply may increase significantly in attenuation.
