case_images: There was mild mass effect on the adjacent pons (Figure 1(a)). Brain MRI performed 3 days later did not demonstrate bleeding either in the cerebellopontine angle mass or elsewhere (Figure 1(b)).

case_images: Noncontrast head CT demonstrated a hyperdense right middle cerebral artery, bilateral basal ganglia calcification, and an occipital falcine mass (Figure 2(a)). Head CT performed at 36 hours demonstrated increasing edema in the distribution of the large right MCA infarct, with midline shift measuring 5 mm, but there was no evidence of hemorrhagic transformation or intratumor bleeding (Figure 2(b)).
