Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: hypernatremia major surgical or invasive procedure: none history of present illness: mr. is a 46 year-old man with a history of pineal dysgerminoma s/p xrt with consequent panhypopit. he was admitted to on for decreased energy. this was thought to be secondary to dehydration due to recently started outpatient lasix, and he received stress-dose steroids and 3l of fluids with improvement in mental status. free t4 was within normal limits. endocrinology was consulted and outpatient meds continued. however, he became hypernatremic (na 134 on admission rose to 144 on and then 174 on ). he was transferred to for his na of 174; he initially was received on the medical floor where repeat na was noted to be 151 (suggesting a 20 point drop in a 12 hour period). he had no apparent change in his mental status, which at baseline, is suggestive of reduced intellectual function s/p pineal gland surgery and xrt. given his rapid change in na, he was transferred to the micu for further monitoring and close follow-up of his serum na and osmolarity. upon transfer, his vitals were stable with hr in 80s, bp of 110/80, rr 18, sao2 of 98% on room air. he had no complaints in the unit following transfer. past medical history: past medical history: -
