Indication:
Nasopharyngeal mass
Findings
- Well-circumscribed , nonenhancing cystic lesion along the midline posterior nasopharynx anterior to the longus colli musculature, compatible with a benign tornwaldt cyst.
Diagnosis
Tornwaldt Cyst
Discussion
-
Tornwaldt cysts are frequently seen as an incidental finding and are benign/developmental in etiology.
-
They are characteristically cystic, rounded/oval, well-circumscribed, and located in the nasopharynx immediately deep to the mucosa, midline, and anterior to the longus colli muscles.
-
Usually can be differentiated from malignancy given their characteristic appearance and location.
-
Rarely they can become infected, cause nasal obstruction, or Eustachian dysfunction.
