Presentation transcript:

An axial T2-weighted MR image (A) reveals mixed signal intensities with minimal surrounding edema in the right posterior mobile tongue. An axial T2-weighted MR image (A) reveals mixed signal intensities with minimal surrounding edema in the right posterior mobile tongue. Gd-enhanced T1-weighted MR image (B) demonstrates relatively well-defined, lobulated, and inhomogeneous ovoid enhancement of the lesion. A small, subtle, dot-like hyperattenuation is revealed on the noncontrast axial CT image (C, arrow), and a linear hyperattenuation on the coronal reformatted CT image (D, arrow). Plain radiograph (D) reveals a linear radiopaque foreign body impacted vertically in the posterior of the mobile tongue (arrow). H.J. Kim et al.
