A variety of extracranial sites have been described for Meningiomas including the nose, various viscera, skin, eye and extraspinal tissue. Among them cutaneous Meningioma generally occur most frequently on the scalp, forehead or paravertebral areas. We are reporting in this article one case of cutaneous Meningioma in the forehead region with respect by reviewing the literatures is very rare tumor. Our patient is a middle age woman with right forehead mass from two years ago, in the skull X-ray and computerized tomography of our case intracranial lesion is not seen and also there is some thickening involving frontal bone. After the surgical excision of the mass and in the microscopic examination of specimens, histopathologic diagnosis is Meningioma (Meningotheliomatous type) and immunohistochemical study react for epithelial membrane antigen. In the clinical course, extracranial Meningiomas enlarge slowly and are usually cured by simple excision alone but incomplete excision may lead to recurrence, the things have been occurred in our patient.

Background and Objective: Brain computed-tomography (CT) scan has a well documented accuracy in detecting the tumors this study was carried out to assess the conformity and correlation of CT-Scan diagnosis of the brain tumors with pathological findings in Ghaem Hospital Mashad University of Medical Sciences-Iran. Materials and Methods: This descriptive prospective study was done on 75 patients, 5-83 years, with the clinical suspicion of brain tumors. According to the CT-Scan findings 1-3 differential diagnosis were made for each patient. This was followed by surgery and biopsy, and the CT-Scan diagnoses were compared with pathological findings. Results: The best conformity and correlation of radiologic and pathologic diagnosis was seen in pituitary adenoma, acoustic neuroma, epidermoid cyst and craniopharyngioma. Also, according to the CT-Scan findings, the highest degree of sensitivity, specificity, positive predictive value and negative predictive value, were related to pituitary adenoma, high grade astrocytoma and meningioma. Conclusion: This study showed thant no single imaging modality may claim optimal sensitivity or specificity for the assessment of CNS disorders, although several imaging methods carry independent and complementary information, and CT-scan has different ability for diagnosis of different kind of tumors.
