Images from the case of a 62-year-old man with malignant lymphoma Images from the case of a 62-year-old man with malignant lymphoma.A, Axial contrast-enhanced T1-weighted MR image obtained before treatment. Images from the case of a 62-year-old man with malignant lymphoma.A, Axial contrast-enhanced T1-weighted MR image obtained before treatment. Thick arrows, thin arrow, and arrowhead indicate edema-like change, incidentally found venous angioma, and tumor, respectively.B, Coronal contrast-enhanced T1-weighted MR image obtained before treatment. High and low signal mass (arrowhead) is visible in the third ventricle. Low signal edema-like changes (arrows) are noted along the optic tracts. A venous angioma was incidentally found in the left anterior basal ganglia, as in A.C, Axial heavily T2-weighted MR image obtained before treatment. Tumor (arrowhead) is visible. Marked edema-like changes are visible in the hypothalamus and midbrain and along the optic tracts (arrows).D, Coronal heavily T2-weighted MR image obtained before treatment. Tumor (arrowhead) is visible. Marked edema-like changes are visible in the hypothalamus and midbrain and along the optic tracts (arrows).E, Axial heavily T2-weighted MR image obtained before treatment. Edema-like changes (large arrows) extend as far as the basal ganglia and the internal capsule. The venous angioma (small arrow) is visible in the left anterior basal ganglia.F, Coronal heavily T2-weighted MR image obtained before treatment. Edema-like changes (large arrows) extend as far as the basal ganglia and the internal capsule. Marked edema-like change is visible in the hypothalamus and midbrain (small arrow).
