Magnetic resonance imaging (MRI). The first MRI suggests an acute infarct in the left basal ganglia. The second MRI scan suggests an expanded infarct in the left basal ganglia. The third MRI suggests acute infarction in the left basal ganglia and right callosum genu and bleeding in the left basal ganglia. MRI, magnetic resonance imaging; T1WI, T1-weighted imaging; T2WI, T2-weighted imaging; DWI, diffusion-weighted imaging.

MRI suggested an acute infarct in the left basal ganglia (Figure 1) and the right posterior horn of the lateral ventricle. A repeat brain MRI suggested expanded infarct lesions in the left basal ganglia (Figure 1). Her brain MRI suggested acute infarction in the left basal ganglia and right callosum genu and bleeding in the left basal ganglia (Figure 1).
Magnetic resonance angiography. Multiple stenoses in the bilateral middle cerebral arteries, anterior cerebral artery, and basilar artery. The red arrows indicate stenosis.

New lacunar infarct lesions in the right corona radiata and stenosis in the bilateral middle cerebral arteries (MCA), anterior cerebral artery (ACA), and basilar artery (BA) were noted (Figure 2).
High-resolution magnetic resonance imaging. Concentric enhancement in the left middle cerebral artery and anterior cerebral artery. Red circles suggest vessel wall enhancement.

Concentric contrast enhancement of the vessel walls was observed in the left MCA and ACA (Figure 3).
Timeline of stroke aggravation and intervention. Stroke occurred on day 1 and was aggravated twice (days 16 and 30). Hexadecadrol was initiated on day 23, roxithromycin was initiated on day 27, and roxithromycin was replaced with doxycycline on day 30. The patient was discharged on day 41.
