Clinical question: Possible stroke. Signs and symptoms: Left upper and/or extremity weakness. Nonenhanced head CT:Examination demonstrates a large area of vasogenic edema in the right frontal lobe there there is an isodense mass measuring 14 times 17-mm in size within the area of vasogenic edema. There is resultant effacement of adjacent cortical sulci however no midline shift is present. There is no evidence of hemorrhage associated with this finding. A questionable area of low attenuation in the inferior aspect of the left cerebellum may represent an additional focus of edema and or an artifact. Recommend follow-up with an MRI exam.
1.Right frontal lobe tumor measuring 17 times 14-mm in size with surrounding vasogenic edema.2.Either artifact or an additional small foci of edema in the inferior left cerebellum.3.Recommend follow-up with an MRI.
