case_images: Patient 1: (A) Diffusion-weighted magnetic resonance imaging (DW-MRI) showing a subtle hyperintense signal in the left internal capsule and thalamus. (B) DSA showing hypoperfusion of the medial and lateral lenticulostriate penetrating arteries (dashed-blue circle). Patient 2: (C) DW-MRI showing a hyperintense signal in the left thalamus and internal capsule. (D) DSA showing a decreased vascular perfusion in the lenticulostriate penetrating arteries of the left middle cerebral artery (dashed-purple circle).

case_images: A follow-up MRI at 24 h was performed and revealed an ischemic infarction in the left internal capsule and left thalamus (Figures 2A, B). T2 and FLAIR-weighted images (Figures 2C, D). The patient was transferred to DSA, which showed decreased vascular perfusion in the lenticulostriate penetrating arteries of the left middle cerebral artery. The diagnostic workup was the same as for patient 1 to rule out other etiologies and differential diagnoses.
