case_images: Brain MRI axial T2 scans (A, B) and postcontrast sagittal T1 (E), showing an expansive formation in the right orbit causing proptosis and extending to the cavernous sinus through the superior orbital fissure. Magnetic resonance angiography revealed developmental venous anomalies in the right frontal and temporal regions and cerebellar hemispheres (C, D).
