A study was conducted to evaluate CT imaging in differentiating nonodontogenic nasopalatine duct cysts from odontogenic radicular cysts. The patient's palatine cystic lesion was analyzed by CT and excised with postoperative microscopic identification. CT findings of a nasopalatine cyst are midline location, smooth expansion with sclerotic margins and displacement of teeth apices. Radicular cysts differ in that the teeth apices are within the cyst rather than being displaced. We concluded that differentiation is clearly demonstrated by CT images.
开展了一项研究以评估CT成像在鉴别非牙源性鼻腭管囊肿与牙源性根囊肿方面的作用。通过CT对患者腭部囊性病变进行分析，并在术后通过显微镜鉴定进行切除。鼻腭囊肿的CT表现为中线位置、边缘硬化的平滑扩张以及牙根尖移位。根囊肿的不同之处在于牙根尖位于囊肿内而非移位。我们得出结论，CT图像能够清晰地显示两者的差异。
