Radiographic Feature of Ameloblastic Fibro- Odontoma : Report of Four Cases and Review of Literature

造釉細胞纖維齒瘤已經被世界衛生組織定爲一好發於兒童的罕見齒源性腫瘤。造釉細胞纖維齒瘤主要出現在後牙區，特別是下顎後牙區。在放射線影像上，造釉細胞纖維齒瘤的表徵大多爲邊缘清楚的放射線透過性影像合併有不透過性影像，且伴隨有未萌發的牙齒。本文報告的目的在研究台灣人口中，造釉細胞纖維齒瘤在影像學上不同的表徵。我們將其分成四類：1.完全放射線透過性影像；2.放射線透過性影像合併少量不透過性影像；3.放射線透過性影像合併多量不透過性影像；4.singleopaquemass放射線透過性影像合併單一放射線不透過性影像。此報告提出台灣族群中造釉細胞纖維齒瘤的影像特徵，以利臨床醫師在影像診斷上的參考，並且加上文獻上的回顧及提出建議的治療方式。

Ameloblastic fibro-odontoma (AFO) has been defined by the World Health Organization (WHO) as a rare odontogenic tumor that is more prevalent in children. AFO usually occurs in the posterior region of the jaws, especially in the mandibular area. In radiographic images, most AFO demonstrates a well-demarcated circumscribed radiolucent lesion containing variable amounts of radiopaque material and usually involved with an unerupted tooth. The aim of this report is to present various types of radiographic images of AFO in the Taiwanese population. We classified these images into 4 groups as follows : 1. total radiolucent without radiopaque material, 2. few proportion of opacities, 3. large proportion of opacities, 4. single opaque mass from x-ray image. The present report is to demonstrate four different types of radiographic images of AFO and four case reports of Taiwanese population.
