Cranial irradiation may lead to accelerated atherosclerotic changes to small or medium sized arteries, but @entity64 associated with pituitary irradiation is not frequent. A @entity1 treated with Gamma Knife radio-surgery (GKRS) for a @entity977 suffered a @entity385 with internal carotid artery occlusion 4 years after radiosurgery. The @entity1 was a 35-year-old male presenting with a visual disturbance. Endocrinological tests were normal. MRI revealed a 4.3 by 4.3 cm diameter invasive macroadenoma of the pituitary, projecting toward the suprasellar region and with cavernous sinus involvement with encasement of both internal carotid arteries (ICAs). GKRS was performed for @entity41 after a transcranial resection. The maximum dose was 40 Gy and the dose to the right carotid artery was below 20 Gy. The delayed @entity1269 was accompanied by a right capsular @entity1188 shown on MRI. The images also showed a marked reduction in @entity5 size. Total, @entity432 was confirmed by Doppler ultrasound. The @entity1 had no history or signs of @entity299 or @entity209 which could predispose to cerebrovascular
