Abstract
- An osteoma of the tongue is a rare benign tumor, typically located in the posterior one-third of the tongue. Several etiological hypotheses have been proposed in previous literature reviews. Herein, we report the case of a lingual osteoma in a 39-year-old woman, who complained of a lump in the throat. The lesion presented as a homogeneously hyperdense submucosal mass without any enhancement in the base of the tongue on CT, consistent with previous image findings of lingual osteoma. After surgical resection, the mass was pathologically proven to be a lingual osteoma. The patient no longer complained of the sensation of a lump. Typical CT findings of a lingual osteoma"”a well-circumscribed hyperdense submucosal mass seen around the foramen cecum"”could be helpful in the diagnosis of lingual osteoma and the prevention of further unnecessary work-up.

Fig. 1 A 39-year-old woman with ligual osteoma, complaining a recently developed lump in the throat. A. The laryngoscopy image shows a small, whitish submucosal mass protruding from the dorsum of the tongue base. B, C. Contrast-enhanced CT axial image with bone window setting (B) and sagittal image with soft tissue window setting (C) show a well-circumscribed, markedly hyperdense oval mass (arrows) with bone density, arising from the base of the tongue without any definite enhancing soft tissue component. D. Photomicrograph shows submucosal mass composed of dense mature lamellar bone (hematoxylin and eosin stain, × 100). E. Photomicrograph shows benign squamous epithelium of the tongue and mature lamellar bone of lingual osteoma (hematoxylin and eosin stain, × 300).
