      Extra- and subligamentous lumbar disk herniations are treated differently. These authors utilized 10 criteria in an attempt to establish the exact location of disk herniations with respect to the posterior longitudinal ligament. Extraligamentous herniations showed: 1) spinal canal compromise of more than half its diameter, 2) internal signal difference in the disk, 3) ill-defined disk margins, 4) disruption of the continuous low-signal-intensity line covering the disk, and 5) presence of an internal dark line in the herniated disk. When combined these 5 yield sensitivity, specificity, accuracy, and an odds ratio of 77.3%, 74.5%, 76.1%, and 9.93, respectively.

      Images from over 500 patients with glioblastoma were used to build location atlases corresponding to genetic and biologic abnormalities as well as prognosis based on age. Most glioblastomas grew into the periventricular regions adjacent to the subventricular zone. MGMT promoter methylated tumors occurred more frequently in the left temporal lobe in young patients, in IDH1 mutant tumors, in those having the proneural gene expression subtype, and in tumors lacking loss of PTEN that occurred most frequently in the frontal lobe. MGMT methylated tumors with IDH1 mutation tended to occur in the left frontal lobe. EGFR amplified and EGFR variant 3-expressing tumors were found most frequently in the left temporal lobe. Tumors in the left temporal lobe were associated with favorable response to radiochemotherapy and increased survival.
