      The quality of the films is not so good.
      I think the finding is at the level of aortic arc but on the right side.

    2. Laurens says:

      There is a nodular lesion located in the projection of right tracheobronchial angle. I also see indistinct left tracheal wall ,above aortic arch, I also suspect a lesion there.
      Additionally, lytic lesion of fifth rib on the right? (mid-axillary line). With all mentioned above, I would suspect metastases.

      ….carissimo dr Pepe…per primo una condiderazione clinica-anamnestica….il soggetto è stato operato di S.Ewing un anno prima,…quindi sono stati fatti dei toraci precedenti….l’immagine era presente nei radiogrammi precedenti o è comparsa dopo? …mi sembra inoltre che , nei campi polmonari, specie a dx, ci siano immagini opache micronodulari….Pertanto , pur essendo quella la sede della v. Azygos, in quella sede ci sono ANCHE linfonodi….In conclusione se l’immagine non era presente nei radiogrammi precedenti e se si confermano , come micrometastasi polmonari quanto visto nei polmoni la conclusione è linfoadenopatia metastatica in sede N2…..

    4. Laurens says:

      If other lesions are excluded (rib and trachea ok) I will go with enlarged azygos vein.

      • Laurens says:

        And I hope for patient’s sake this isn’t because of vertebroplasty material leakage into vascular system.

    5. genchi bari italia says:

      ….carissimo dr pepe…la lesione è quindi connessa con la malattia di base:sarcoma di Ewing…..Se escludiamo l’adenopatia metastatica allora l”opacità è la vena azygos “dilatata”….tenendo presenti le connessioni emodinamiche del vaso, la sua dilatazione potrebbe rappresentare lo “scarico collaterale” di una eventuale occlusione della CVI(vena cava inferiore), occlusa su base trombotica-metastatica….

    6. MP says:

      On the PA view the right hila appears to be elevated with respect to the left. There is also a faint rounded opacification just superior to the right hila. The lateral view seems to show a rounded irregular opacification in the middle mediastinal compartment just anterior to the spine. The patient has a history of Ewing sarcoma which I believe most frequently gives metastases to bone and the lungs. I would consider this a suspicious lesion and follow-up with a CT to rule out metastatic disease.

    7. Dr. Pepe says:

      At this time of the day I can safely congratulate Laurens for being the first to mention the azygos vein and Genchi Bari for giving an explanation of the findings.
      Full answer tomorrow.
