Rhinolith

Definition: A calcification in the nasal cavity.

Radiographic Features:

Location: Nasal cavity, will appear superior to the floor of the nasal cavity on a pantomograph.

Edge: Well-defined, smooth or irregular outline.

Shape: Round, ovoid, irregular.

Internal: Radiopaque, may have a ‘laminated’ appearance with radiopaque and radiolucent bands evident due to continued laying down of calcium salts.  (This looks similar to layers of an onion.)

Other: None

Number: Typically single.

TIP: A maxillary standard occlusal radiograph is helpful to determine the location before a cone beam CT is recommended.
