Hard candy. Hard candy. Sagittal reconstruction from enhanced CT shows a curvilinear attenuation (arrowheads) in the oral cavity representing a ring-shaped intraoral foreign body. The attenuation is similar to that of the contrast-enhanced vessels, and the inferior aspect of the foreign body is obscured by dental amalgam, such that the foreign body might be mistaken for an enlarged vessel or vascular abnormality.
