Sialo-cutaneous fistula with ectopic submandibular gland sialolith, revealing a hidden ipsilateral enlarged and elongated styloid process: a consideration based on CT findings

We report herein an unusual case of a 49-year-old obese man with sialo-cutaneous fistula containing a large, ectopic sia lolith in subcutaneous tissue that was expected to undergo spontaneous elimination, but revealed hidden Eagle syndrome featuring an ipsilateral enlarged, elongated styloid process. Furthermore, we offer a thorough review of the literature regarding sialo-fistulae and highlight the relationship betwe en an abnormal styloid process and submandibular sialadenitis with sialolithiasis and new tract formation based on computed tomography.
