Legend Axial noncontrast CT images show low attenuation in the left perisylvian region with mild mass effect upon the adjacent lateral ventricle. There is some increased density along the medial margin of the lesion that may represent hemorrhage.

Legend Following contrast administration there is abnormal heterogeneous enhancement within the area of edema. A definite mass is not identified.

Legend There is heterogeneous signal intensity and worsening mass effect on axial T2WI.

Legend Coronal T1W image shows a heterogeneous mass in the left temporal and adjacent frontal lobe. Coronal and axial T1W post Gd images demonstrate irregular nodular enhancement of the mass. Key words: mri tumor neoplasia
