A case of schwannoma in the tongue diagnosed with enhanced magnetic resonance image

Abstract

We encountered a case of schwannoma of the tongue in a 74-year-old man, who complained chiefly of contact pain in an ulcer in the left sublingual region. Although by computed tomography we could not differentiate the lesion as a cyst or tumor, with magnetic resonance (MR) imaging we diagnosed a benign tumor on the basis of lesion enhancement. Axial and coronal MR imaging revealed the three-dimensional location of the lesion. This case showed that enhanced MR imaging is useful for the differential diagnosis of a benign tumor in the oral cavity.
