Initial non-enhanced head computed tomography (CT) revealed no hemorrhage but showed hypodensity throughout the left frontal lobe and left insular lobe, indicating acute ischemia (Figure 1).
Axial diffusion-weighted image and apparent diffusion coefficient showed acute infarction in the left temporal lobe, left insular lobe, left basal ganglia, and left radial crown 24 h after admission.

Post-rt-PA magnetic resonance imaging (MRI) found multiple cerebral infarctions (Figure 2), and contrast-enhanced MRI revealed that the hypodense area in the left insula and frontal lobe was edema adjacent to a tuberculoma but not ischemia (Figure 3).
MRI revealed nodular enhancement in the left pontine cistern.
