Very nice video, thank you. The IASLC nodal scheme describes the changeover between lower paratracheal and hilar node stations at the lower margin of the azygos vein on the right, and the upper rim of the left main pulmonary artery on the left, not the carina as you mention in the video. I appreciate the added description of other nodal disease not discussed in the IASLC framework.
Thanks for your comment, yes you're right I should have mentioned that. The IASLC document describes these nodes as immediately adjacent to the mainstem bronchi and hilar vessels, so that's why I described it the way I did. The landmarks you point out are more accurate. Incidentally, nodes that are anterior to the carina, I would still classify as right paratracheal.
Good luck to the team of physicians and consultants in endocrinoligy dental gynae and gastroentrogy and medical nano technology team looking into my care. From kathelizjenruddy
Amazing video! Thank you I just uploaded a blog post about chest anatomy on my website and used some of the images from this video (with the reference). Please let me know if you don't want your contents to be reused and I will delete them.
Hi Rishi.. Can ypu pls explain this ultra sound report comment.. "Multiple upto 37 x 13.5 mm sized porta peri pancreatic enlarged lymph nodes" What could it be.. I am very scared
PET is an imaging modality that uses a radioactive tracer to cause certain tissues to light up. In the case of F-18 FDG PET, the radiotracer goes to tissues that are highly metabolically active. In the case of a hypermetabolic lymph node, that could be due to cancer, or it could be from other things like sarcoid, infection, or other inflammatory diseases. the AP window is a location in the chest.
Out of curiosity, are infraclavicular lymph nodes examined / visible on a thorax CT? You mentioned supraclavicular nodes, but not infra. Not a medical professional, just an enthusiast - so excuse my ignorance :)
Hi Rishi, Thanks for sharing a nice talk. Just to ask regarding nodal chart you refereed, it is 8th edition. Are you still using same chart or any updated version (as this talk was uploaded about 3 years ago)? Secondly, i couldn't find any satisfactory answer about few subcentimeter thoracic nodes we see in our routine practice in patient with inflammatory conditions or in known malignancy situations. Referring services expect us to comment on these particularly on 1st / baseline study.
Yes I frequently see 9-10 mm nodes in connective tissue disease which I do mention in the report. In known malignancy, I don't usually mention small nodes unless they are unusual, for example enlarging nodes or nodes where there are usually no nodes like near diaphragm, pleura, and internal mammary.
Sorry for asking 1 more question. If you found a patient with chest ct and there is 0.7 size paratracheal node, and the lung itself is normal. Do you think he need a repeated Ct?
