To provide a classification of orbital tumors based on compartmental location and age of presentation.
To describe the main radiologic features of orbital tumors,
including contributions of advanced imaging techniques.
A wide range of processes can produce space-occupying lesions inside the orbit.
Most of them arise from orbital contents.
Cross-sectional imaging has been traditionally used for detection and mapping.
latest techniques allow differentiation between aggressive and non-aggressive tumors and might play a valuable role in characterization of these lesions.
A general approach to orbital tumours should consider the anatomic compartment of involvement as a first step.
The globe is located centrally in orbit.The eyeball will not be discussed in this review.
Findings and procedure details
In the last years a compartment-based classification has become popular.
This classification method is easier to manage and remember and creates less confusion between radiologists.
We will revise this classification,
emphasizing the most frequent tumour-types on each category and their main radiological features.
Not included in this review.
Tumours related to skin and conjunctival tumours,
accessible to biopsy.
Imaging techniques are used to assess orbital invasion.
Optic nerve-sheath complex tumours:
Optic nerve glioma...
Orbital tumors compromise a diverse group of lesions,
complex to characterize and challenging for radiologists.
A useful strategy is to make a diagnosis based on compartmental location,
combined with advanced MRI techniques,
which can help to narrow our differential diagnosis.
