The linguofacial trunk (LFT) is the conjoined origin of the lingual (LA) and facial (FA) arteries. We present an uncommon case of LFT due to its origin, length, and diameter. The computed tomography angiogram of an adult male case was evaluated. On the right side, the external carotid artery (ECA) gave off a large LFT before reaching the greater hyoid horn, with an outer diameter of 3.7 mm. The outer diameter of the ECA of 3.4 mm. The ECA and the LFT were on the outer side of the greater hyoid horn. After an ascending course of 20.9 mm anteriorly to the ECA, the LFT branched into the LA and FA. Bilateral elongated styloid processes reaching laterally to the oropharyngeal isthmus were also assessed. In conclusion, care should be taken not to confuse a large LFT with the ECA on the outer side of the greater hyoid horn.
