In a case of median nasal fistula with a cyst accompanied by recurrent infection around the nasal root, a 73-year old woman was reported. Imaging study showed a subcutaneus cyst and fistula tract penetrating the left nasal bone to the nasal mucosa. The fistula and cyst were removed. Pathological examination revealed a dermoid cyst. Cases of median nasal fistula should be studied by CT and MRI and operated on due to the possibility of the cyst extending to the skull base.
