[Imaging of orbital tumors in children].

Orbital tumors in children are characterised by a wide histological diversity due to the architectural complexity of the orbit. Several classifications may be proposed according to their location, histologic type and malignant or benign character. The most common clinical manifestation is the leukocoria. Diagnostic delay of these tumors, even if they are benign, may affect prognosis and lead to a loss of vision and/or a morphological deformation. Imaging plays an important role in positive diagnosis, in the differentiation between benign processes and potentially malignant processes, in the assessment of local and loco-regional staging and in follow-up monitoring under treatment. This study aimed to highlight the radiological features of primary intra-orbital tumors in children which are, in general, different from those of adults, by conducting a retrospective study of 40 medical records whose data were collected in the Division of Pediatric Radiology at the Mohammed VI University Hospital in Marrakech, Morocco over a period of 4 years (2014-2017).
