Figure 2. Magnetic resonance imaging of the brain with and without contrast. There are 2 enhancing lesions seen in the right and left posterior frontal aspect of the brain. There can also be seen moderate vasogenic edema surrounding the lesions. Mild diffusion restriction is noted at the periphery of these masses. There is no associated hemorrhage. No additional lesions are seen. The brain otherwise appears to be of normal volume and formation, without midline shift, herniation, or hydrocephalus.
