Patient with intra-orbital varicosity A1. Appearance when the patient was sitting, Hertel’s exophthalmometry revealed 2 mm of enophthalmos of right eye; A2. Appearance when the patient had bent down and bowed his head for 1 min, 4 mm of proptosis of right eye than the left; B. Horizontal MRI and coronal scan(supine position), showed a superotemporal ribbonlike mass in the extra-conal orbital compartment. The lesion displayed isointense on T1-weighted images (B1), hyperintense on T2-weighted images (B2), and significantly heterogenous contrast enhancement on enhanced and fat suppression MRI scan (B3–5). C. Axial CT scanning (prone position, the symbol of the right eye “R” was opposite to that on the MRI) showed a right superotemporal huge spindle-shaped homogenous mass pushing the eyeball to protrude and extending to the orbital apex. The superior rectus, lateral rectus and optic nerve were difficult to identify. D. CDFI (30 mmHg pressure was applied to the neck by the cuff of sphygmomanometer) showed a ribbonlike well defined hypoechoic mass expanded. The lesion was affecting the lateral rectus and pushed the optic nerve moving inward. There were signals of blood flow in the lesion. The arrow pointed to the lesion in Fig. 2
