FIG 4. The case of a 69-year-old woman 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 homogeneous intrasellar mass extending inferiorly, with remodeling of the sellar floor.
B, Tensor diffusion-weighted MR image (b = 1000 mm2/s) shows isointensity within the pituitary mass (arrows) compared with that in normal brain.
C, ADC map shows isointensity within the pituitary mass (arrow) compared with that in normal brain; mean ADC was 0.90 (10–3 mm2/s).
