The case of a 64-year-old man with histologically confirmed pituitary adenoma without evidence of hemorrhage or infarction.A, Coronal spin-echo T1-weighted MR image (500/20 [TR/TE]) shows a large homogeneous intrasellar mass compressing the optic chasm, consistent with a nonhemorrhagic macroadenoma.B, Coronal spin-echo T1-weighted MR image (500/20) shows diffuse uniform enhancement after the administration of contrast medium (0.05 mmol/kg).C and D, Tensor diffusion-weighted MR images (b = 1000 mm2/s) show isointensity within the pituitary mass (arrows) compared with that in normal brain.E and F, ADC maps show isointensity within the pituitary mass (arrows) compared with that in normal brain.
