Tumors of the orbit

This short review will present an overview not only of the findings in imaging, but the main clinical symptoms of the different orbital space occupying lesions, (not only different tumors, but even tumor-like lesions), as those should be included in differential diagnostic consideration. This should lead to a targeted diagnostic procedure in the individual patient. Basic knowledge of orbital anatomy is as important as the knowledge of the pros and contra's of computed tomography (CT) and magnetic resonance imaging (MRI), which should influence the examination protocol. Imaging findings of the most important tumors/lesions of the globe, the intraconal and extraconal space as well as of the optic nerve are presented with different examples (without any demand of completeness).
