    Odontogenic keratocyst is the most likely diagnosis. Lucent, unilocular and expansile make it the most likely diagnosis. When it does not arise from an unerupted tooth then it is most likely an odontogenic keratocyst. When associated with an unerupted, impacted or embedded tooth consider dentigerous cyst. 囊性、单房、膨胀性病变,这些特点最符合牙源性角化囊肿,尤其是非起源于一个未萌出牙时,反之,合并有阻生齿或埋伏牙时,需要考虑含齿囊肿。W4X影像园cn-diwater.com

    Ameloblastoma is usually locally invasive, bubbly mixed cystic and solid mass involving the posterior mandibular ramus associated with an unerupted 3rd molar tooth.W4X影像园cn-diwater.com

    造釉细胞瘤通常有局部的侵蚀性,表现为多囊泡状改变和和实性的肿块,累及下颌支后部伴有未萌出的第三磨牙。W4X影像园cn-diwater.com

    Dentigerous cyst is a radiolucent, well circumscribed, expansile cyst surrounding crown of unerupted, impacted or embedded tooth. Pathology is needed to differentiate this lesion from an odontogenic keratocyst.W4X影像园cn-diwater.com

    含齿囊肿是一个囊性、边界清楚、膨胀性肿块,环绕着未萌出的牙、阻生齿、埋伏齿等,病理上需要与牙源性角化囊肿相鉴别。W4X影像园cn-diwater.com

    Basal cell nevus syndrome is associated with multiple mandibular and maxillary odontogenic keratocystsW4X影像园cn-diwater.com

    基底细胞痣综合症常常伴有多发的下颌骨、上颌骨角化囊肿。W4X影像园cn-diwater.com

【要点】:Odontogenic keratocysts also known as primordial cysts arises from remnants of dental lamina. 牙源性角化囊肿又被称为始基囊肿,起源于牙板的残留。W4X影像园cn-diwater.com

     Theses cysts make up 10% of jaw cysts and are associated with Noonan and Marfan syndrome. 这些囊肿占颌囊肿的10%,并且常伴有Noonan氏和Marfan氏综合症。W4X影像园cn-diwater.com

    The natural history of odontogenic keratocysts are rapid growth with high recurrence rate. Treatment is with enucleation and aggressive curettage.a牙源性胶质囊肿发展迅速,复发率高,治疗包括摘除术和大范围的刮除术。
