Case Discussion
CT features of a fistulous communication, between a chronic dental infective focus and a cutaneous superficial septic focus most consistent with an odontogenic cutaneous fistula.
Odontogenic cutaneous fistulae are rare and occur when chronic dental infection is complicated by a fistulous tract reaching the skin, usually in the chin or cheek regions.
