Fig 4.

Sagittal T1-weighted image (500/14/3) in a 33-year-old woman with a 26-mm GH-secreting macroadenoma. No postoperative DI occurred. The figure 3 appearance of the high-signal-intensity area (arrows), which corresponds to ADH storage, is considered eutopic and ectopic at the same time. This shape is probably due to the compression of the hypothalamohypophyseal tract filled with ADH vesicles by the sellar diaphragm.
