  Cerebellar Watershed Injury in Children

  Focal signal abnormalities at the depth of the cerebellar fissures in children have been reported and hypothesized to represent a novel pattern of bottom-of-fissure dysplasia. The authors report a series of 23 patients with a similar distribution and appearance of cerebellar signal abnormality attributable to watershed injury. T2 prolongation was observed at the depths of the cerebellar fissures bilaterally in all 23 patients, centered at the expected location of the deep cerebellar vascular borderzone. Diffusion restriction was associated with MR imaging performed during acute injury in 13/16 patients. Five of 23 patients had prior imaging, all demonstrating a normal cerebellum. The etiology of injury was hypoxic-ischemic injury in 17/23 patients, posterior reversible encephalopathy syndrome in 3/23 patients, and indeterminate in 3/23 patients.

  Initial MRIs from 50 subjects with diffuse intrinsic pontine gliomas recruited for a prospective clinical trial before treatment were analyzed. Retrospective imaging analyses included FLAIR/T2 tumor volume, tumor volume enhancing, the presence of cyst and/or necrosis, median, mean, mode, skewness, kurtosis of ADC tumor volume based on FLAIR, and enhancement at baseline. Molecular subgroups based on EGFR and MGMT mutations were established. Histone mutations were also determined (H3F3A, HIST1H3B, HIST1H3C). Enhancing tumor volume was near-significantly different across molecular subgroups, after accounting for the false discovery rate. Tumor volume enhancing, median, mode, skewness, and kurtosis ADC T2-FLAIR/T2 were significantly different between patients with H3F3A and HIST1H3B/C mutations.

  Predictors of Cerebral Aneurysm Rupture after Coil Embolization: Single-Center Experience with Recanalized Aneurysms

  The authors evaluated a total of 426 unruptured aneurysms and 169 ruptured aneurysms that underwent coil embolization in their institution between January 2009 and December 2017. Recanalization occurred in 38 (8.9%) of 426 unruptured aneurysms and 37 (21.9%) of 169 ruptured aneurysms. The Modified Raymond-Roy Classification on DSA was used to categorize the recanalization type. In untreated recanalized aneurysms, class IIIb aneurysms ruptured significantly more frequently than class II and IIIa. In the ruptured group, the median follow-up term was 28.0 months. Retreatment for recanalization was performed in 16 aneurysms. Four of 21 untreated recanalized aneurysms (2.37% of total coiled aneurysms) ruptured. Class IIIb aneurysms ruptured significantly more frequently than class II and IIIa. Coiled aneurysms with class IIIb recanalization should undergo early retreatment because of an increased rupture risk.

  The Impact of Intracortical Lesions on Volumes of Subcortical Structures in Multiple Sclerosis
  I. Kalinin, G. Makshakov and E. Evdoshenko
  
  American Journal of Neuroradiology May 2020, 41 (5) 804-808; DOI: https://doi.org/10.3174/ajnr.A6513
  
  The authors investigated the impact of intracortical lesions on the volumes of subcortical structures (especially the thalamus) compared with other lesions in 71 patients with MS. The volumes of intracortical lesions and white matter lesions were identified on double inversion recovery and FLAIR imaging, respectively, by using 3D Slicer. Volumes of white matter T1 hypointensities and subcortical gray matter, thalamus, caudate, putamen, and pallidum volumes were calculated using FreeSurfer. They conclude that thalamic atrophy was explained better by intracortical lesions than by white matter lesion and T1 hypointensity volumes, especially in patients with more profound disability.
