A tumor-like foreign body in the maxillary sinus is reported. Examination of the paranasal sinuses by computerized tomography revealed a dense and well defined lesion equal to that of bone in the left maxillary sinus. After surgery, the lesion was found to be alginate used for impression-taking before fitting of a prosthesis, and not a tumor.
报告了一例上颌窦内类似肿瘤的异物。通过计算机断层扫描检查鼻窦发现，左侧上颌窦内有一个密度高且边界清晰的病变，与骨质相当。手术后发现该病变是在安装假体前用于取模的藻酸盐，而非肿瘤。
