| 摘 要： | Objective: To assess MRI in the evaluation of enlarged superior ophthalmic vein (SOV). Meth-ods：MRI manifestations and etiology of forty-six patients with enlarged SOV were analyzed. Results: SOV enlargement was noted to occur in carotid-cavernous fistula, ophthalmic Graves‘ disease, Tolosa-Hunt syn-drome, inflammation at the apex of the orbit, orbital pseudotumor and thrombosis of cavernous sinus. The dilated vein appeared as signal void tubular shadows on both T1 and T2 weighted images. The diameter of the enlarged vein was 3.5 — 6.0 mm. Extraocular muscle enlargement, orbital pathologies, enlarged carotid cav-ernous sinus etc were also revealed by MRI. Conclusion: The dilated SOV may be well demonstrated by MRI. The etiological diagnosis of enlarged SOV can be made in combination with the associated findings.
