Meningiomas are common and mostly benign intracranial tumors, which originate from arachnoid cells of the meninges, and account for approximately 25% of all primary intracranial tumors. Many external etiological factors have been described as etiology of meningioma in the literature, one of which is head trauma. However, trauma as a cause of meningioma remains a controversial subject. Here, a case of a patient with posttraumatic meningioma, who was wounded 25 years before, is presented. The assessment of the clinical characteristics of the patient and those reported in the literature seem to confirm that, in some cases, head trauma may be a factor contributing to the development of meningioma.
