Abstract Objective: To investigate the MR imaging features of cerebral cortical laminar necrosis(CLN). Methods: The MR imaging materials of 17 CLN patients diagnosed in our hospital ranged from January 2012 to October 2014 were retrospectively analyzed. The MRI characteristics were studied. Results: CLN was detected from 12 to 32 d since the patients were admitted. The affected regions were bilateral cerebral hemisphere(3/17), unilateral cerebral hemisphere(14/17), then the single lobe(11/17), double lobes(4/17), multiple lobes(2/17). On MRI, the gyral shape lesion showed high intensity on T1WI and fluid-attenuated inversion-recovery(FLAIR), lesions showed more clearly on original three dimensional time of flight magnetic resonance angiography(3D-TOF MRA) images, ill defined on T2WI, 12 patients manifested as high intensity on DWI. No hemorrhagic focus showed on SWAN in 6 patients. Conclusion: Typical imaging features could be revealed in CLN, which is high intensity on MRI T1WI. Accurate diagnosis could be obtained with imaging examination in combination with clinical history.
