Figure 1: Growth hormone producing pituitary macroadenoma in a 43-year-old woman. Tumor consistency was judged as hard at surgery. Coronal apparent diffusion coefficient map and diffusion-weighted imaging (a and b) images show hypointense signal from the tumor (red star) compared with normal brain tissue. The photomicrograph (c) shows abundant fibrous stroma (collagen is depicted in blue color: arrow) with scant cellularity
