SUMMARY

This paper describes a 52-year-old woman with an orbital paraganglioma that was completelly removed through a lateral orbitotomy. Paragangliomas are benign tumors, extremelly rare in the orbit with only 28 cases previously reported. Our patient had a lesion that enhanced markedly on computerized tomography scan. Magnetic resonance imaging studies revealed that the tumor was isointense in T1, hipointense in T2 and showed enhancement with the administration of gadolinium. These findings, as well as the clinical ones, are very important in the differential diagnosis of these lesions.
