Abstract：
UNASSIGNED: The aim of the current study was to analyse the demographic, clinical and radiological features of primary aneurysmal bone cysts (ABCs) involving the maxillofacial region.
UNASSIGNED: Histologically confirmed cases affecting the maxillofacial region were retrospectively reviewed over a 21-year period (2000-2021). Cases were collected from the archives of five Oral Pathology laboratories from three countries: South Africa, Guatemala and Brazil. The information was analysed, with emphasis on the clinical and radiological spectrum.
UNASSIGNED: Following the inclusion criteria, a total of 31 cases of primary ABCs were included in the study. A nearly equal male-to-female distribution was seen, with ABCs occurring in males at an earlier age compared to females. Localised swelling was the main clinical presentation. ABCs had a mandibular predominance, particularly in the posterior regions. All ABCs presented as blow-out expansile well-demarcated radiolucent lesions with the majority having a multilocular appearance. Cortical expansion was seen in 91% of cases with loss of cortical integrity being common (78%).
UNASSIGNED: Primary ABCs involving the maxillofacial region are extremely rare with the majority of current published literature consisting of isolated case reports. The current study is the first large series detailing the radiological features.

摘要：
未经评估：本研究的目的是分析人口统计学，涉及颌面部的原发性动脉瘤性骨囊肿（ABCs）的临床和放射学特征。
UNASSIGNED：对21年（2000-2021年）影响颌面部区域的组织学确诊病例进行回顾性分析。病例是从三个国家的五个口腔病理学实验室的档案中收集的：南非，危地马拉和巴西。对信息进行了分析，重点是临床和放射谱。
未经评估：按照纳入标准，本研究共纳入了31例原发性ABCs.男女分布几乎相等，与女性相比，男性发生ABC的年龄较早。局部肿胀是主要临床表现。ABC的下颌占优势，特别是在后部区域。所有ABC都表现为吹出的可膨胀的边界清晰的射线可透性病变，大多数具有多房性外观。在91％的病例中观察到皮质扩张，皮质完整性丧失是常见的（78％）。
未经证实：涉及颌面部区域的原发性ABCs极为罕见，目前发表的大部分文献都是孤立病例报告。当前的研究是第一个详细介绍放射学特征的大型系列。
