Tornwaldt’s cyst is an uncommon midline nasopharyngeal cyst that arises from the pharyngeal bursa on the posterior nasopharynx. They represent as a communication between notochord remnants and the pharyngeal endoderm. Occlusion of this communication results in the formation of Tornwaldt’s cyst. Development of these cysts has been linked to scarring from prior adenoidectomy and nasopharyngeal inflammation. It is usually small and accidentally diagnosed on rhinoscopy, computerized tomography (CT) or magnetic resonance imaging (MRI). Clinical symptoms of nasopharyngeal cysts may include fullness in the ear, tinnitus, nasal obstruction, dysphagia, dysarthria, dysphonia, odynophagia, halitosis, cephalgia, or stiffness of cervical muscles. We report a case of a 24-year-old male with as an isolated nasal obstruction and discuss the clinical, radiological features, and the differential diagnosis of these cysts
