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. ANATOMIC CONSIDERATIONS A general approach to orbital tumours should consider the anatomic compartment of involvement as a first...

CLASSIFICATION METHODS 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. COMPARTMENT-BASED CLASSIFICATION GLOBE TUMORS Not included in this review. ANTESEPTAL COMPARTMENT Tumours related to skin and conjunctival tumours,
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.
