3例颌骨角化型成釉细胞瘤:病例报道及影像学特征分析
|
Abstract:
摘要 目的: 探讨角化型成釉细胞瘤的影像学特征,并结合文献资料讨论其影像学鉴别诊断。方法: 搜集2011~2017年我院经病理证实罕见的角化型成釉细胞瘤3例,回顾性分析并总结3例角化型成釉细胞瘤的影像学特征,并结合现有文献对于其鉴别诊断进行探讨。结果: 3例角化型成釉细胞瘤中,发病部位均位于左下颌骨体和升支部,共同的影像学特征为膨胀性不均匀密度影,边界呈扇贝样及虫蚀状,其内见不均匀性稍高密度影,部分伴有钙化致密影。结合文献,其主要与原发性骨内鳞状细胞癌、恶性成釉细胞瘤及颌骨中央性巨细胞病变进行鉴别。结论: 角化型成釉细胞瘤影像学上同时兼具良性及恶性特征表现。识别典型角化型成釉细胞瘤的影像学特征有助于本病的诊断及手术方案制定,此外更多的病例报道对于可以准确诊断这一罕见的角化型成釉细胞瘤至关重要
