多种病理状况可能起源于眼眶。虽然通常根据疾病类别（例如肿瘤和炎症）进行鉴别诊断，但将眼眶分割为解剖区域可以指导放射科医生了解每种表现和空间最常见的病理状况。眼眶可分为锥内室、锥内室和锥外室。此外，视神经鞘复合体和泪腺装置由于其独特的功能和病理特征可以分为单独的隔室。通过使用这种解剖方法，作者回顾了影响眼眶的最常见病理状况，并讨论了可以指导外观相似病变的鉴别诊断的临床和影像学发现。根据 CC BY 4.0 许可证发布。本文提供了补充材料。

A wide range of pathologic conditions can originate in the orbit. While it is common to approach the differential diagnosis based on disease categories, such as neoplastic and inflammatory, segmenting the orbit into anatomic compartments can direct the radiologist toward the most common pathologic conditions for each manifestation and space. The orbit can be divided into intraconal, conal, and extraconal compartments. Additionally, the optic nerve sheath complex and lacrimal apparatus can be partitioned into separate compartments due to their unique functions and pathologic features. By using this anatomic approach, the authors review the most common pathologic conditions affecting the orbit and discuss clinical and imaging findings that can guide the differential diagnosis for lesions with similar appearances.
