From: Prevalence and imaging characteristics of detectable tonsilloliths on 482 pairs of consecutive CT and panoramic radiographs

Figure 5

Cases with tonsilloliths are detected on CT images, but not on panoramic radiographs. A) Panoramic radiographs at the palatine tonsillary level of a 65-year-old male. A radiopaque nodular mass is not seen. B) Axial CT images at the palatine tonsillary level of the same patient as in Figure 5A. Tonsilloliths (arrowheads) are seen at the level of the mandibular teeth as high-density, oval-like structures with a long axis of 5.03 mm and 1128 HU. C) Panoramic radiographs at the palatine tonsillary level of a 32-year-old female. A radiopaque nodular mass is not seen. D) Axial CT images at the palatine tonsillary level of the same patient as in Figure 5C. Tonsilloliths (arrowheads) are seen at the level of the mandibular teeth as high-density, oval-like structures with a long axis of 5.96 mm and 912 HU. E) Panoramic radiographs at the palatine tonsillary level of a 48-year-old female. A radiopaque nodular mass is not seen. F) Axial CT images at the palatine tonsillary level of the same patient as in Figure 5E. Tonsilloliths (arrowheads) are seen at the level of the mandibular teeth as high-density, oval-like structures with a long axis of 5.35 mm and 905 HU.
