Caceres’ Corner: Case No.18 (Update: Solution)

Dear Friends,

Muppet is in a good mood today (Miss Piggy may be responsible for that) and wants to present a ‘wysiwyg’ case (what you see is what you get).

64-year-old, asymptomatic male. Chest images taken one month after an episode of myocardial infarction.


1. Aortic aneurysm
2. Aortic elongation
3. Type A aortic dissection
4. Type B aortic dissection

    1. Alice says:

      I would go for elongation and very likely aneurysm and do a ct. You can not rule out a dissection without contrast… ??

    2. andreea says:

      Can it be a marfan syndrome with aortic aneurysm of the descending aorta?

    3. Marce says:

      2. Evidently there is a aortic elongation.
      The retrosternal space is clear, so, there is any ascending aortic aneurysm.
      In the AP projection I am not sure to identify both margins of the descending aorta, so it make me difficult so say if there is an aneurysm. I need a CT

      • Jose Caceres says:

        Performing an enhanced CT is the only way to have a definite diagnosis. But it’s more cool to suggest a possible diagnosis with the plain film.

    4. Genchi Bari Italia says:

      l’aorta discendente è tutta dilatata proseguendo con un kinking nel tratto addominale : si veda la netta differenza di calbro in LL, tra,aorta ascendente e quella discendente.SI veda in ap un arco normale e la netta impronta-dislocazione della trachea. Non ci sono segni di scompenso del piccolo circ olo ed il paziente è aSINTOMATICO. lA DIAGNOSI PIù PROBABILE è DI ANEURISMA AORTCO-ADDOMINALE( TIPO c CLASS. safi).UNA ANGIO-TC CON RICOSTRUZIONE IN 3 D, DOVREBBE CONFERMARE LA DIAGNOSI.

    5. vaggoul says:

      The correct answer should be A. aortic aneurysm (the aorta is dilated as shown better in lateral view)
      C + D should be excluded on clinical grounds (asymptomatic patient)

      • Jose Caceres says:

        What if the dissection happened a few months ago?

        • vaggoul says:

          A type A dissection would require some kind of therapeutic intervention which is not apparent here. So if that is case it should be a type B dissection.

          Another remark is the presence of a moderate pectus excavatum (better appreciated in the lateral film) which can be related to Marfan syndrome and vascular compromise.

    6. DAG says:

      Aortic elongation

    7. Adam says:

      Type B aortic dissection – maybe a PTA complication? He probably had one in myocardial infarction episode.

    8. VINCENZO GENCHI says:


    9. saly says:

      i think it is aortic aneurysm, i cannot see the signs of aortic dissection by X-ray like calcium sign. widening of the mediastinum, pleural or pericardial effusion and i can determine the wall of the aorta well on contrary to the dissection.
      NB are you sure that Muppet in good mood with this case.

      • Jose Caceres says:

        Muppet is in excellent mood! (perhaps miss Piggy was a good influence). Happy to see you all sending answers.
        He wishes to give all of you a diagnostic pearl.

    10. Susan says:

      Looks a little like an old aortic coarctation because of the step from arcus to descending aorta – and aortic aneurysm with or without dissection (only type B seems to be realistic, if even…)- here I need a second method, e.g. CTA or MRI. Dissektion as complication of PCI would be an type A most of all.

    11. Alice says:

      Ok back to the beginning: I guess there are signs for type B dissection – double aortic contour on level of aortic knob, and unusual placement of atherosclerotic plaques on distal descending aorta.

    12. Vilma says:

      Type B aortic dissection

    13. Monofiner Med says:

      Dissection type A…Because we can clearly see the silluete of the aorta, and the silluete of the dissection maybe all over the thoracic aorta.

    14. yasir jamil khattak says:

      I think there can be two pathologies at a time a well, i.e aneurysm along with dissection but i ll go with aortic aneurysm since there has to be one choice.

    15. kailash says:

      It looks like type B aortic dissection,as here is a sharp widening and a thin line is present at the point of widening.But asymptomatic patient suggest more towards aneurysm.

    16. Marce says:

      For an aortic dissection I would like to see the displaced intimal calcification, but in this case i don’t see it.

      The X ray, show an enlarged and elongated descending aorta

    17. Marius says:

      Aortic dissection Stanford type B. Intimal calcification flap is visible on profile at the superior limit of aorta at the site of the change in caliber. Sinuous descending aorta. Pectus excavatum.

    18. Elen says:

      I would go for Type B Aortic Dissection for all the reasons that have already been mentioned. Then I remembered a friend of yours with “abnormal” mediastinum on the plain film due to pectum excavatum ( ECR 2012 ). So I got confused!

      • José Caceres says:

        Pectus will give an abnormal cardiac silhouette , but should not alter the aortic contour.

    19. Adriana Barreiro says:

      Type B dissection (the lateral view shows an indentation in the begining of the desending aorta), maybe an aneurysm, a contrast CT is needed.

    20. J says:

      Pectus excavatum? Isn’t it pectus carinatum?
