Tonsilloliths, also known as tonsil stones or tonsils calculi, are clusters of calcifications that form into tonsillar crypts within the tonsils or around them. Although they are an uncommon benign finding, they may be symptomatic (pain, halithosis, etc.).

Radiographic features

Small foci of calcifications seen within the tonsils are diagnostic of tonsillolith. They usually are a fortuitous finding on CT-scan. With more important foci of calcifications, foreign bodies and neoplasm must be excluded, although these entities will usually be easy to distinguish from simple tonsilloliths.
