Palpation showed reducible, soft and swinging mass, at the upper internal angle of the orbit, with impairment and varix of upper eyelid (Figure 1), ocular motility was mildly restricted (Figure 2).

Diagnostic assessment: computed tomography scan of the orbit showed a vascular lesion of the upper internal angle of the left orbit (Figure 3).
(A) orbito encephalic MRI; (B) axial and coronal T1 section: image of orbital mass in upper internal angle of left orbit, the lesion has an in heterogeneous hypersignal with serpiginous appearance; (C) axial T1 section with gadolinium enhancement, the mass has intense contrast enhancement; (D, E, F) axial and coronal T2 section, axial diffusion section: heterogeneous hypersignal lesion with serpiginous appearance mimicking an arteriovenous malformation

Magnetic resonance imaging (MRI) revealed an orbital vascular mass of the left internal canthus, measuring 3 x 2.7 x 2.4 cm in diameter and responsible for a grade II proptosis with scalloping on the internal orbital wall (Figure 4).
(A,B) histological examination finding endothelial cells with solid area of fibrosis and papillary hyperplasia limited to vascular wall without atypical features
