Objective To explore the MR imaging characteristics and the clinical application value of lesions of orbits tumors in extraconal compartment. Methods Analyzed the MR imaging characteristics of 67 patients with orbits tumors in extraconal compartment retrospectively, all of them were confirmed by surgical pathology. Results Totally find out 78 lesions in orbital extraconal compartment, 27 cases in left eye and 31 cases in right eye, 9 case in bilateral. Lymphoproliferative diseases account for 24 cases, 22 of them growing along with the orbital structure and showed isointensity on T1WI and isointensity or hyperintensity on T2WI, and 2 cases showed isointensity on T1WI and T2WI. A total of 9 cases were inflammatory disease, and showed isointensity on T1WI and hypointensity or hyperintensity on T2WI. Three cases were cancer, and showed slight hypointensity on T1WI,slight hyperintensity on T2WI. Vascular tumor account for 5 cases, which showed hypointensity on T1WI and hyperintensity on T2WI. Benign tumor were 16 cases, which showed hypointensity on T1WI and hyperintensity on T2WI, 4 cases were cystic mass, showed hypointensity on T1WI and hyperintensity on T2WI, 6 cases showed hyperintensity on T1WI and T2WI, however 4 cases dermoid cyst showed characteristic signal decrease after fat suppression on T1WI and T2WI. Conclusion MR imaging can clearly show the characteristic of orbital tumors in extraconal compartment, and it's an important method in the differentiation, diagnosis and preoperative localization for orbital tumors in extraconal compartment.
