Tonsilloliths Diagnosis and Management

Introduction to Tonsilloliths

Tonsilloliths are calcified concretions that form within the crypts of the palatine tonsils due to chronic inflammation, and are relatively common findings on panoramic radiographs, typically appearing as radiopaque shadows on imaging 1

The American College of Chest Physicians guidelines state that solid nodules that have been stable for at least 2 years do not require additional diagnostic evaluation, which applies to the case of a small radiographic dot on the lower left side of the throat that has remained unchanged in size for 2.5 years 1
The Fleischner Society guidelines emphasize that stability over time is a strong indicator of benignity for any type of nodule, which supports the benign nature of a tonsillolith that has remained unchanged in size for 2.5 years 2

Small calcifications in the tonsils are common and typically benign, with nasopharyngeal tonsilloliths often being less than 1 cm in size and frequently detected on imaging when there are no clinical symptoms, and the absence of symptoms such as dysphagia, odynophagia, or foreign body sensation further supports the benign nature of this finding 1
The American College of Chest Physicians guidelines clearly state that solid nodules stable for at least 2 years do not require additional diagnostic evaluation, which applies to the case of a small radiographic dot on the lower left side of the throat that has remained unchanged in size for 2.5 years 1
