Answer

A study by Wang et al indicated that the extent of deformation of the third ventricle and hypothalamus, as evaluated through preoperative magnetic resonance imaging (MRI), may help to predict the occurrence of DI subsequent to transcranial surgery for pituitary adenoma. The investigators found a positive correlation between the degree of deformation of the third ventricle and hypothalamus and the development of immediate postoperative DI, with postoperative hemorrhage also being linked to a higher degree of deformation. Moreover, postoperative hemorrhage was found to be associated with permanent DI. [35]
