OBJECTIVES
Calcifying cystic odontogenic tumour (CCOT) is a rare disorder of the jaw. A comparison between conventional radiographs and CT images in CCOTs has not been reported. The purposes of this study were to analyse conventional radiographs and CT images of CCOTs, establish CT images of CCOTs and assess the utility of CT in the diagnosis of CCOTs.
METHODS
Nine patients with a histopathologically confirmed CCOT who had both conventional radiographs and CT images were enrolled.
RESULTS
CT was superior to conventional radiographs in detecting buccolingual expansion, odontomas and radio-opaque bodies.
CONCLUSION
The characteristic CT appearances of CCOT were that radio-opaque bodies were typically located in the periphery of the lesion and the shape of radio-opaque bodies was linear and/or spotted. CT was useful in diagnosing a CCOT.
目的
牙源性钙化囊性瘤（CCOT）是一种罕见的颌骨疾病。目前尚未有 CCOT 的常规 X 线片与 CT 图像比较的报道。本研究旨在分析 CCOT 的常规 X 线片和 CT 图像，建立 CCOT 的 CT 图像，并评估 CT 在 CCOT 诊断中的应用价值。
方法
本研究纳入了 9 例经组织病理学证实的 CCOT 患者，这些患者均同时接受了常规 X 线片和 CT 检查。
结果
CT 比常规 X 线片更能检测颊舌向膨胀、牙瘤和不透射线体。
结论
CCOT 的典型 CT 表现为不透射线体通常位于病变的外周，形状为线性和/或斑点状。CT 有助于诊断 CCOT。
