Fig 1. 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).

Fig 2. T2-weighted MR image (A) demonstrates subtle and ill-defined hyperintensity to the right of the middle of the tongue. Gd-enhanced T1-weighted MR image (B) reveals a 4 x 1.6-cm, vertically ovoid, target-like enhancement. The PET-CT image (C) demonstrates a hypermetabolic lesion in the right tongue with a measured peak SUV of 7.4. Noncontrast axial (D) and sagittal reformatted (E) CT images show a small foreign body (arrow) within the slightly hyperattenuated lesion of the anterior tongue.
