Fig. 10From: Role of magnetic resonance imaging in characterization of central nervous system lesions in pediatric patients with leukemia and post-treatment complicationsLeft orbital leukemic infiltration. Female patient 17 years old diagnosed as Burkitt’s leukemia presented by left orbital swelling. Axial MRI of the brain: a, b Non-contrast T1WI and c, d axial FLAIR images show left intra-orbital mass infiltrating the superior rectus muscle (arrow) and extending to the pre-septal space (thick short arrow). The mass is of intermediate signal in T1WI and bright signal in FLAIR images. e DWI and f ADC of the same patient show diffusion restriction of the orbital mass. g, h Axial post-contrast MRI of the orbit with the patient with fat saturation shows avid enhancement of left orbital massBack to article page
