[Pathologic studies of pituitary changes with hypertensive hemorrhage].
The pituitarism of 20 deaths from hypertensive cerebral hemorrhage at different periods were studied pathologically. No matter where the location of intracerebral hemorrhage may be, and how much the content of hemorrhage may involve, usually there are some changes in pituitary could be observed. Early period of the cerebral hemorrhage show the expansion, congestion and edema interstitial venous sinus of anterior pituitary; after then empty bulb degeneration of anterior spongy degeneration and necrosis etc may be taken place. The pathologic changes of pituitary is induced by the following three factors: 1. Blood penetrates into cerebral ventricle and pituitary. 2. Blood mass was formed after hemorrhage--increment in intracerebral pressure pressed by cerebral herniation. 3. The disturbance caused by cerebral blood circulation after cerebral hemorrhage makes the pituitary primary plexus obstructed and pituitary destroyed.
