(a) Computed tomographic scan showed a focal lesion in the white matter of the left cerebral hemisphere. (b) FLAIR magnetic resonance imaging sequences showing lesion with surrounding cerebral edema that involved posterior central cerebral convolution, posterior limb of internal capsule, corpus callosum of the left hemisphere, and right central cerebral convolution.

For this reason, a computed tomography (CT) scan was performed, and it highlighted a focal lesion with enhanced border, measuring 15 mm, in the white matter of the left cerebral hemisphere (Figure 1(a)). Magnetic resonance imaging (MRI) of the brain confirmed the presence of a lesion with surrounding cerebral edema that involved posterior central cerebral convolution, posterior limb of internal capsule, corpus callosum of the left hemisphere, and right central cerebral convolution (Figure 1(b)).

A positron emission tomogram (PET) scan also showed fludeoxyglucose (FDG) uptake in the left lateral paraventricular region (SUVmax 11.2) (Figure 2).
