Abstract：
The radicular cyst is the most common odontogenic cyst and is caused by inflammation. It can become atypically large, although the size of the radiographic osteolysis says nothing about the entity of the lesion. This case shows an unusually large multilocular radicular cyst expanding buccally from tooth 46 in a patient with severe autism who can only be treated under general anesthesia. The clinical and radiological picture as well as the intraoperative situation was more indicative of an aggressive cyst or benign tumor. The lesion was surgically completely removed and the teeth 46, 47 and 48 were extracted because of poor compliance and prognosis. Histopathology revealed a radicular cyst. There were no postoperative complications. After eight months, the lesions had almost completely reossified.
摘要：
根性囊肿是最常见的牙源性囊肿，由炎症引起。它可以变得非典型的大，尽管放射学骨质溶解的大小并不能说明病变的实体。该病例显示，患有严重自闭症的患者只能在全身麻醉下治疗，异常大的多房性根性囊肿从牙46向颊扩张。临床和放射学图片以及术中情况更能表明侵袭性囊肿或良性肿瘤。由于依从性和预后差，手术完全切除了病变，并拔除了46、47和48颗牙齿。组织病理学显示根性囊肿。术后无并发症发生。八个月后,病变几乎完全重新骨化。
