Radiology of Abnormal Globe Contour

The orbits are easily identified on routine computed tomography (CT) and magnetic resonance imaging (MRI) imaging of the head and neck. Although there are many structures within the orbits, the overall structure of the globe is the most noticeable and can be an important source for pathology. In particular, many disease processes alter globe morphology and it is imperative that the radiologist be aware of not only the most common, but uncommon etiologies as well. This article provides an image-rich review of the wide range of emergent and non-emergent pathology that can result in altered globe contour.
