Fig 2. A, Contrast-enhanced axial CT scan at the level of hyoid bone revealed a well- defined mixed attenuation mass that has expanded to the left lesser cornu and has replaced the normal body of the hyoid bone with peripheral rim calcification and internal chondroid calcification. The right lesser cornu cannot be demonstrated.

B, Contrast-enhanced coronal CT scan revealed a round well-defined inhomogeneous attenuation mass with peripheral rim calcification and internal chondroid calcification below the floor of the mouth.
