a Diffusion-weighted imaging 95 min after symptom onset demonstrating a large volume of tissue infarction within the right hemisphere. b Noncontrast CT scan at 180 min showing hemorrhage within the right basal ganglia and extension into both lateral ventricles. c Serial coregistered images during the MRI showing the appearance and growth of hematoma (arrows) over time from the beginning of the scan. Diffusion-weighted sequence: b = 0 s/mm2; T1-weighted image; arterial spin-labeled perfusion image, unprocessed data.

She underwent a perithrombolysis MRI scan with initial diffusion-weighted imaging confirming extensive acute ischemic stroke and no evidence of hemorrhage at that time (fig. 1a, c). Six minutes into the sequences, an increasing mass effect was noted on the reformatting images within the head of the right caudate and ventral putamen (fig. 1c). Immediate CT confirmed extensive intraventricular hemorrhage with early hydrocephalus (fig. 1b).
