Fig 5. A 61-year-old woman with hemangioblastoma; postcontrast T1WI (TR/TE = 525/17 ms) (A), T2WI (2500/15 ms) (B), perfusion image by ASL (C), and CD-34–immunostained histopathologic specimen with the dark gray color overlaid on vessel lumen areas (x20) (D). A, Postcontrast T1WI shows a strongly enhanced mass (arrow) in the right cerebellar hemisphere. B, T2WI shows a high-signal-intensity mass (arrow) with surrounding edema. C, Perfusion image by ASL shows remarkably high signal intensity (%Signal intensity = 524%) (arrow). D, The image analysis of the CD-34–immunostained histopathologic specimen shows attenuated vascular proliferation (%Vessel = 36.0%).
