The purpose of this study is to examine the correlation between histopathologic and radiographic findings and to discuss the cause of the simple bone cyst.
Histopathologically, we classified 53 simple bone cysts into two types. Type A has a connective tissue membrane and type B has a partially thickened wall with dysplastic bone formation. Radiographically, we evaluated the following: margin, radiolucency, or radiopacity, relationship with tooth apices, bucco-lingual bone expansion, and displacement of the mandibular canal.
Bone expansion and radiopacity were closely related to histopathologic findings although there was no correlation between the histopathologic findings and radiographic margin, relationship with tooth apices, and displacement of mandibular canal. Local recurrence was more likely to be observed in patients diagnosed as having type B than type A lesions.
Type A and type B bone cysts may have different causes. Cysts determined radiographically to be radiopaque, those diagnosed as type B histopathologically, and cysts that have been treated surgically should all be followed by radiographic examinations.
本研究旨在探讨组织病理学与影像学表现之间的相关性，并讨论单纯性骨囊肿的病因。
在组织病理学方面，我们将53例单纯性骨囊肿分为两种类型。A型有结缔组织膜，B型有部分增厚的壁并伴有发育异常的骨形成。在影像学方面，我们评估了以下内容：边缘、透光度或不透光度、与牙根尖的关系、颊舌侧骨膨胀以及下颌管移位。
骨膨胀和不透光度与组织病理学表现密切相关，尽管组织病理学表现与影像学边缘、与牙根尖的关系以及下颌管移位之间没有相关性。诊断为B型病变的患者比A型病变患者更易出现局部复发。
A型和B型骨囊肿可能有不同的病因。影像学上表现为不透光的囊肿、组织病理学诊断为B型的囊肿以及接受过手术治疗的囊肿都应进行影像学检查随访。
