Maxillary sinus can pose diagnostic dilemma radiographically because of its anatomical variation which can mimic a periapical pathosis. This case report deals with one such diagnostic problem, where a maxillary sinus was interpreted in an intraoral periapical radiograph as a periapical cyst. With the advances in imaging techniques, the use of an Ultrasound imaging together with application of Colour Power Doppler helped in revealing the contents of the radiolucent area and come up with an accurate diagnosis. Thus a thorough knowledge about the normal anatomy and its variations and proper diagnostic aids are essential in the diagnosis of periapical pathology.
由于上颌窦的解剖变异可模仿根尖周病变，因此在影像学上可能会造成诊断难题。本病例报告涉及这样一个诊断问题，即在一张口腔根尖片上，一个上颌窦被误诊为根尖囊肿。随着成像技术的进步，超声成像结合彩色能量多普勒的应用有助于揭示透射区的内容物并得出准确诊断。因此，对正常解剖结构及其变异有全面的了解以及使用合适的诊断辅助手段对于根尖周病变的诊断至关重要。
