case_images: A, Endoscopic view of nasopharynx with left torus tubarius demonstrating irregular and
  lobular changes to the submucosal tissue. Similar changes could be seen of the right
  eustachian tube. B, MRI T1 fat suppressed post-contrast image which demonstrates cystic
  lesions of the bilateral tori tubarius with surrounding isointensity.

case_images: Nasopharyngoscopy demonstrated irregular, lobular, submucosal enlargement of bilateral tori tubarius (Figure 1(A)). MRI with contrast showed cystic lesions within the bilateral tori tubarius (Figure 1(B)).
case_images: A, Low power view shows sections of an oncocytic proliferation arising within a dilated
  mucoserous gland, or retention cyst, of the nasopharynx. Cyst lining shows papillary
  projections lined by oncocytic cells. Nasopharyngeal epithelium is seen overlying the
  cyst. B, This high power view shows bland oncocytic epithelium, which in some areas has
  a bi-layered appearance, lining papillary projections into the retention cyst.
