Abstract

  1. 1.

    MR is generally preferred since it shows mucosal and parapharyngeal extensions better while CT is reserved for cases with skull base and spine involvement.

     
  2. 2.

    CT is the imaging of choice for nasopharyngeal angiofibromas in view of their vascularity but once they extend intracranially, MR provides better idea of the extensions.

     
  3. 3.

    Angiography and preoperative embolization is generally preferred in cases of angiofibromas prior to surgical excision.

     
  4. 4.

    PET-CT is the imaging modality of choice for assessing posttreatment relapses in Ca nasopharynx as well as in evaluation of lymphomas involving the nasopharynx.

     
  5. 5.

    In MUO (metastasis of unknown origin), CT or PET-CT may help identification of occult primary in nasopharynx.
