Dentigerous cyst appears surrounding the crown of an included tooth. On the radiographic exam, a radiolucent rounded well-defined lesion can be observed.
This study reports a clinical case of a 34-years old man with a pericoronal radiolucent lesion associated to an impacted lower third molar with the presence of radiopaque material inside. The radiological differential diagnosis was calcifying odontogenic tumor, adenomatoid odontogenic tumor and dentigerous cyst. The impacted third molar was removed and the lesion was sent for the histopathological exam.
The histopathological diagnosis was dentigerous cyst with capsular calcifications. Specifically, parietal calcifications on its connective wall and a piece of cemento-osseous tissue inside.
Non-neoplastic lesions such as dentigerous cysts could develop radiopacities inside the radiolucent pericoronal area. Dentigerous cyst, calcifications, third molar, differential diagnosis.
含牙囊肿出现在阻生牙牙冠周围。在影像学检查中，可观察到一个圆形、边界清晰的透射性病变。
本研究报告了一例34岁男性患者的临床病例，其下颌阻生第三磨牙周围存在透射性病变，内部有不透射线物质。放射学鉴别诊断包括钙化性牙源性肿瘤、腺样牙源性肿瘤和含牙囊肿。拔除了阻生第三磨牙，并将病变送去做组织病理学检查。
组织病理学诊断为含牙囊肿伴包膜钙化。具体表现为其结缔组织壁上有壁层钙化，内部有一块牙骨质 - 骨组织。
非肿瘤性病变如含牙囊肿可在透射性的冠周区域内形成不透射线区。含牙囊肿、钙化、第三磨牙、鉴别诊断。
