Radiolucent lesions within the jaws represent a whole variety of lesions. Generally, they can be classified into two categories. The first category comprises well circumscribed lesions, either unilocular, multilobular or multilocular. They may be further subdivided into odontogenic or nonodontogenic lesions. The key feature that distinguishes these two subgroups is the relationship with the underlying dentition. Poorly circumscribed radiolucent lesions are the second category and consist of acute infectious disease and primary or metastatic malignancies. Although many of these lesions may present with non-specific imaging characteristics, careful analysis of a combination of imaging parameters may suggest a presumptive diagnosis. This article discusses the imaging features on different imaging techniques that may be useful in the characterization of these lesions.
颌骨内的透射性病变代表了各种各样的病变。一般来说，它们可分为两类。第一类包括边界清晰的病变，可为单房性、多叶性或多房性。它们可进一步细分为牙源性或非牙源性病变。区分这两个亚组的关键特征是与下方牙列的关系。边界不清的透射性病变是第二类，包括急性传染病以及原发性或转移性恶性肿瘤。尽管这些病变中的许多可能表现出非特异性的影像学特征，但仔细分析一系列影像学参数可能会提示一个初步诊断。本文讨论了不同成像技术上的影像学特征，这些特征可能有助于对这些病变进行特征描述。
