X-ray showed a rounded soft tissue mass arising from the alveolus which had multiple small calcifications and a large triangular calcification resembling a partly formed vertebra [Figure 1b]. Computed tomography showed similar findings with absence of hyoid bone and no intracranial, retropharyngeal, or parapharyngeal extension [Figure 1c].

The excised specimen measured 12 x 8 x 5 cm and cut surface revealed the majority of the lesion to consist of soft with fleshy areas, one being cystic with few areas of calcifications [Figure 2b]. Microscopic examination showed presence of neural tissue, cartilages, bone, epididymis, and vas deferens with intestinal epithelium [Figures 2c and 2d].
