Ameloblastic carcinoma (AC) is a rare malignant odontogenic tumor. Surgical resection of the tumor is the mainstay of its treatment. To date, radiotherapy for this tumor remains controversial. This report describes a case of AC with intracranial extension and provides the first report of the efficacy of single-fraction helical tomotherapy for the treatment of residual AC after surgical resection.
