Introduction: intracranial meningiomas, with extension into the orbit through bone, the superior orbital fissure, or the optic canal, and optic nerve sheath meningiomas can lead to proptosis and visual loss. In this study we evaluated meningiomas’s cases presented with proptosis in Ghaem Hospital from 1374 to 1384 with respect to etiological factors, clinical findings, imaging studies, histopathological and prognostication. Materials and Methods: we reviewed medical records of fifty patients that because of orbital mass and proptosis underwent cranio-orbital surgery, then cases of meningiomas (a with respect to pathology) selected. The chi-square test was used for the statistical analysis. Results: Of fifty cases with proptosis, 6 cases (12%) were meningiomas with orbital involvement. In 6 meningioma’s cases, 5 (83%) were intracranial sphenoid wing meningiomas with orbital extension and 1 (17%) was optic nerve sheath meningiomas. Of six patients with meningiomas’s diagnosis, there were women (67%) and men. Mean age of patients in secondary meningiomas was 54.4 years (43-70 years) and in one primary meningiomas age was 21 years. In all cases there was decreased vision in addition to proptosis. Conclusion: The most common orbital meningiomas were secondary that arise intracranial. Visual loss is frequent; The most common cause of proptosis in neurosurgery ward is sphenoid wing meningiomas.
