Images in a 49-year-old women with leptomeningeal carcinomatosis from adenocarcinoma of the lung. Images in a 49-year-old women with leptomeningeal carcinomatosis from adenocarcinoma of the lung. MR images in A–C were obtained at the acute stage (4 days after symptom onset).A, Axial T2-weighted image shows localized subcortical low intensity (arrow) in the right parietal lobe.B, Axial FLAIR image also demonstrates subcortical low intensity in the same area, with adjacent sulcal hyperintensity. Hyperintensity of cortex is not demonstrated on T2-weighted or FLAIR images.C, Contrast-enhanced T1-weighted image demonstrates diffuse leptomeningeal enhancement in both hemispheres. Strong leptomeningeal enhancement adjacent to the subcortical low-intensity lesion is also seen in the right parietal lobe. Jae Hee Lee et al.
