摘要

鼻腭管囊肿(NPDCs)是上颌骨最常见的非牙源性囊肿,通常是诊断成像的偶然发现。当出现症状时,通常表现为无痛性肿胀,可能伴有瘘管。常规x线摄影显示上颌中门牙根部之间有圆形到卵形或心形的透光度。虽然基于x线的NPDCs的放射学特征已经被很好地描述,但其磁共振成像(MRI)特征很少被报道。近年来,牙科核磁共振技术的发展和各种牙科核磁共振技术的引入,使其在牙科医学中得到了广泛的应用。MRI正在成为发现和诊断偶发或非偶发牙颌面囊肿的重要工具。本报告介绍并讨论了2例NPDC病例的MRI特征,采用传统的和新实施的特殊牙科MRI方案,采用新型的15通道下颌线圈,展示了这些方案在无辐射颌面诊断中的应用。

Appearance of nasopalatine duct cysts on dental magnetic resonance imaging using a mandibular coil: Two case reports with a literature review.

Nasopalatine duct cysts (NPDCs), the most common non-odontogenic cysts of maxilla, are often incidental findings on diagnostic imaging. When symptomatic, they usually present as a painless swelling with possible fistula. Conventional radiography shows a round-to-ovoid or heart-shaped radiolucency between the roots of central maxillary incisors. While the radiographic features of NPDCs in X-ray-based modalities have been well described, their magnetic resonance imaging (MRI) features have rarely been reported. Developments in dental MRI in recent years and the introduction of various dental MRI protocols now allow a wide range of applications in dental medicine. MRI is becoming an important tool for the detection and diagnosis of incidental or non-incidental dentomaxillofacial cysts. This report presented and discussed the characteristics of 2 NPDC cases visualized on MRI using both conventional and newly implemented specific dental MRI protocols with a novel 15-channel mandibular coil, demonstrating the use of these protocols for radiation-free maxillofacial diagnoses.
