Figure 3 Computed tomography (CT) scan of the cranial, cervical, and thoracic regions reveals a “tongue-like” soft-tissue mass in the nasopharyngeal apex extending into the nasopharyngeal cavity toward the left posterior-inferiorThe mass contacts the vertical plate of the ethmoid bone anteriorly, connects with the adenoid superiorly, and has an unclear boundary with the left nasopharyngeal side wall. The other margins are well-defined and free, measuring approximately 15×5×6 mm (anteroposterior×vertical×transverse diameter). The lesion shows homogeneous density with a CT value of approximately 49 Hounsfield units. There is no significant destruction of adjacent bone, and no clear communication with the intracranial region. The left posterior nasal cavity is notably obstructed and narrowed.
