Antrochoanal polyp

Discussion:

An antrochoanal polyp (ACP) is a solitary polyp that arises within the maxillary sinus but passes to the nasopharynx through the sinus ostium and posterior nasal cavity,

The MRI signal characteristics of this case are typical:

  • T1: intermediate to low signal
  • T2
    • high homogeneous T2 signal
    • signal may vary if they are chronic and/or if fungal infection is present
  • T1 C+ (Gd): peripheral enhancement is seen on post-contrast images.
