Because of the close anatomical relationship between the maxillary sinus and the adjacent dental region, determining the primary site of cysts in these regions can be a diagnostic dilemma. In this article, two cases with similar radiological findings are presented. These cases had lesions involving the maxillary sinus and the adjacent alveolar process; the lesions were surrounded with egg-shaped, linear opacities. Diagnoses of a residual radicular cyst in one case and a calcified mucocoele (which is very rare) in the other case were predicted with the help of radiological findings and were confirmed surgically and histopathologically.
由于上颌窦与相邻牙区之间存在紧密的解剖关系，确定这些区域囊肿的原发部位可能会成为诊断难题。本文介绍了两例具有相似影像学表现的病例。这些病例的病变累及上颌窦和相邻的牙槽突；病变周围有椭圆形的线性不透光区。借助影像学表现，一例诊断为残余牙根囊肿，另一例诊断为钙化黏液囊肿（非常罕见），并经手术及组织病理学证实。
