Meningiomas have been described as the most frequent extra-axial tumor in the brain. Most are benign and correspond to World Health Organization (WHO) grade I; however, there are some reports of cases that shows atypical locations, like subcortical intra-axial meningiomas. This represents a challenge in radiological diagnosis because it could be taken as a metastasis tumor or vascular malformations. The authors bring a case report of a previously healthy patient who presents a traumatic brain injury with no traumatic lesions. A computed tomography (CT) evidenced a left frontal rounded subcortical lesion surrounded by large vasogenic edema. The first diagnostic impression was a metastasis tumor. During surgery, a total resection was completed, and the appearance of the tumor was meningioma. This was later confirmed by histological analysis. The literature was reviewed in order to determine the importance of including intraparenchymal meningiomas in the differential diagnosis of intracranial lesions.
