    1. Cocotet says:

      The iris heterochromia suggests me neurofibromatosis therefore it may be neurogenic tumour?
      Moreover it is not water density in CT so i discard the other two options.

      Lisch nodules NF1

      • Jose Caceres says:

        Quote from the NEJM: “Lisch nodules are melanocytic hamartomas that appear as well-defined, dome-shaped elevations projecting from the surface of the iris and are clear to yellow or brown”. Does this patient have Lisch nodules?

      Branchial cyst

    4. gus says:

      She didn’t come for her eyes that means is something not acquired recently.
      the mass extends above the superior clavicle on the face view so it is located either in the neck or in the posterior mediastinum.
      on CT the mass it looks like solid from the neck to the mediastinum
      Lisch nodules NO
      Waardenburg syndrome NO
      Congenital Horner’s syndrome ? but we don’t have all the symptoms of Horner’s syndrome

      • Jose Caceres says:

        This case was diagnosed by the resident searching the web. Of course, you have to look for the right information. This is why it is important to make a correct interpretation of the findings.

      paraganglioma ?
      schwannoma ?

    6. Konstantinos Drevelegas says:

      It is probably a lesion of the posterior mediastinum. I go for lymphocele.

      ..eterocromia, ma anche mosaicismo somatico occhio dx, da S,di Claude-B-Horner, per neuroblastoma toracico.

    8. Mirzada Irshad says:

      Cervicotoracic sign. Means most probably the mass is in posterior medistnium. Most peobably neurogenic tumor. Schwanoma with iris color change … Will go for NF 1.

    9. Dr. Pepe says:
