      Brain Magnetic Susceptibility Changes in Patients with Natalizumab-Associated Progressive Multifocal Leukoencephalopathy
      J. Hodel, O. Outteryck, S. Verclytte, V. Deramecourt, A. Lacour, J.-P. Pruvo, P. Vermersch and X. Leclerc
      American Journal of Neuroradiology December 2015, 36 (12) 2296-2302; DOI: https://doi.org/10.3174/ajnr.A4436

      These authors retrospectively evaluated 12 patients with natalizumab–progressive multifocal leukoencephalopathy (PML), 5 with PML from other causes, and 55 patients with MS without progressive PML for comparison. They observed T2* or SWI signal abnormalities at the chronic stage in all patients with PML, but in patients without PML no areas of low SWI signal intensity were detected. PML—related to natalizumab or not—induces brain susceptibility changes within U-fibers or deep gray matter that are visible on T2* or SWI and potentially explained by iron deposition.

    1. EDITOR'S CHOICEAdult Brain
      Diagnostic Accuracy of PET, SPECT, and Arterial Spin-Labeling in Differentiating Tumor Recurrence from Necrosis in Cerebral Metastasis after Stereotactic Radiosurgery
      G. Lai, A. Mahadevan, D. Hackney, P.C. Warnke, F. Nigim, E. Kasper, E.T. Wong, B.S. Carter and C.C. Chen
      American Journal of Neuroradiology December 2015, 36 (12) 2250-2255; DOI: https://doi.org/10.3174/ajnr.A4475

      The authors retrospectively reviewed patients treated between 2007–2010 and identified 14 patients with cerebral metastasis who had clinical or radiographic progression following stereotactic radiosurgery and were imaged with arterial spin-labeling (ASL), FDG-PET, and thallium SPECT before stereotactic biopsy. FDG-PET and ASL were equally sensitive in detecting tumor progression (83%). The specificity of ASL was superior to that of the other modalities (100%, 75%, and 50%, respectively). A combination of modalities did not augment the sensitivity, specificity, positive predictive value, or negative predictive value of ASL.

      Risk Factors for Hemorrhagic Complications following Pipeline Embolization Device Treatment of Intracranial Aneurysms: Results from the International Retrospective Study of the Pipeline Embolization Device
      W. Brinjikji, G. Lanzino, H.J. Cloft, A.H. Siddiqui and D.F. Kallmes
      American Journal of Neuroradiology December 2015, 36 (12) 2308-2313; DOI: https://doi.org/10.3174/ajnr.A4443

      In this study of 793 patients with 906 aneurysms, 20 (2.5%) had intraparenchymal hemorrhage. Nine patients with intraparenchymal hemorrhage (45.0%) died, 10 (50.0%) had major neurologic morbidity, and 1 (5.0%) had minor neurologic morbidity. Variables associated with higher odds of intraparenchymal hemorrhage included treatment of ruptured aneurysms and the use of 3 or more Pipeline Embolization Devices. The Shuttle sheath was not associated with intraparenchymal hemorrhage.
