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

Radiographic features

Small foci of calcifications seen within the tonsils, most likely represent tonsilloliths, and are usually incidental findings on CT. However, potentially more serious etiologies of tonsillar calcification, e.g. foreign bodies and neoplasm need to be excluded, although these entities will usually be easy to distinguish from simple tonsilloliths.
