Primary central nervous system lymphoma (PCNSL) involving the pituitary stalk. A 60-year-old male with generalized body malaise. The pituitary stalk is enlarged with contrast enhancement on contrast-enhanced T1WI (arrows) (a, b) and hyperintensity on diffusion-weighted imaging (DWI) (arrow) (c). d DWI showing hyperintensity lesion along the ventricular wall DWI showing hyperintensities along the ventricular wall (arrows), which represents hypercellularity. Brain biopsy confirmed a diffuse large B-cell lymphoma
