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: horse/equine product derivatives attending: chief complaint: blurry vision on the left visula field. major surgical or invasive procedure: right craniotomy for resection of right optic tract glioma. tissue biopsy history of present illness: 73 year-old righ handed male who has noiced blurry vision on the left visual field while doing his crossword puzzle and playing golf.his visual problem got worse over time mri -/+ gadolinium in and hospital showed an enhancing mass in the optic chiasm and the right optic nerve. there was a spot of enhancement as well as t2 and fl ir hyoerdensities in the left cereberal peduncleand left insula. any headcahe, nausa, vomiting, seizure or fall. patient was placed on a dexamethasone without any imporovement on his vision. patient refeered to dr by dr for surgical evaluation. after long discussion with patient benefits, risk of surgery by dr patient and family decided to have an elective surgery. past medical history: htn hyperlipidemia. social history: lives with wife, fully independent with at home prior to surgery. tobacco: 1ppdx20 years.quit in . etoh:occ family history: strong family hsitory of esophageal ca.(grandmother, sister, first cousin w/ esophageal ca). physical exam: vital signs: 97.3 76 16 195/58 98% ra preo holding area. gen: elderly man nad, = in strecther. skin:good turgor tonus, no ecchymosis. heent: neck supple, no coratid bruits, sclera unicteric/no hemorrhage. cvs: rrr, s1/s2, no m/g/r. chest: cta a/p bilat. abd: soft, nontender, nondistended, bowel sounds present. ext: no edema, no clubbing, pp+/bilat. neuro: alert, awake, orientedx3. language fluent with good comprehension. cn: pupils are equal reactive to light, 4 mm to 2 mm bilaterally. there is no afferent pupillary defect. extraocular movements are full. visual field examination shows a left hemianopsia in os and a left upper quadrantaposia in od. funduscopic examination reveals sharp disks margins bilaterally, but his right optic nerve is a slightly pale. his face is symmetric. facial sensation is intact bilaterally. his hearing is intact bilaterally. his tongue is midline. palate goes up in the midline. sternocleidomastoids and upper trapezius are strong. motor examination: he does not have a drift. his muscle strengths are at all muscle groups. his muscle tone is normal. his reflexes are 0-1 bilaterally. his ankle jerks are absent. sensory examination is intact. coordination examination does not reveal dysmetria. his gait is normal. he does not have a romberg. pertinent results: glucose-167* urea n-28* creat-0.8 sodium-133 potassium-4.3 chloride-102 total co2-22 anion gap-13 calcium-7.0* phosphate-3.5 magnesium-1.8 wbc-14.0* rbc-4.38* hgb-13.5* hct-40.6 mcv-93 mch-30.8 mchc-33.3 rdw-13.4 plt count-117* pt-12.7 ptt-21.0* inr(pt)-1.1 head mri; showed an enhancing lesion in the right optic nerve, right optic tract, and the optic chiasm. there was also an enhancing spot in the left parietal white matter, as well as increase flair and t2 signals in the left cerebral peduncle and the left insula. eeg: markedly abnormal portable eeg due to the persistent and somewhat rhythmic bursts of slowing with some sharp features broadly over the right hemisphere. this suggests a focal subcortical abnormality, likely of a structural or distructive nature. the rhythmic appearance of slowing and occasional sharp features raises concern for the possibility of lateralized epileptogenesis, but there were no clear seizures during the recording. an atomic correlation would be of interest if clinically indicated. reflective of some drowsiness, over the left side. tissu pathology ; #1, optic track lesion biopsy (including intraoperative smear): anaplastic astrocytoma with gemistocytic features. who () grade iii out of iv. brief hospital course: 73 year-old male underwent right craniotomy for resection of right optic track glioma, and tissue biopsy under general anesthesia on /5.no intraoperative complications occurred. easily extubated. patient closely monitored in the pacu for q1 hour neuro check and sbp goal of 100-140 mmhg ovenight.star to taper his decadron pod#1 to mg until in the brain tumor clinic. postop head mri with/without gadolinium revealed status post craniotomy, mass in the optic chiasm is visualized. no evidence of hemorrhage, mass effect or hydrocephalus. signal abnormalities in the brain stem and left insular region. no evidence of acute infarct. patient developed hyponatremia on pod#3, na 121, started 3% sodioum iv fluid restriction initiated and salt tabs able to normolize sodium level.on na:132 borderline low, continue fluid restriction to 1000ml a day. check serum sodium level periodically in rehab. advanced his diet as tolareted, able to void without any difficulty.pod#5 () patient had a whitnessed seizure activity by staff, potable eeg showed abnormal eeg, dilantin 1 gm load then, 100mg tid started.dilantin 7.6 , dilantin level 18 on current dose.reloaded and dose increased to 200mg . on on morning rounds patient was slow to respond on neuro exam , repeated head ct was stable, later in the day neuro exam was better. spiked a low grade fever 101 pan cultures obtained. urine dipsitick showed trace blood, tr ketone, tarce protein, glucose 250, urobil: 12, no leukocit. blod culutere an durine cultures are pending, if they becaome postive will contact with patient for treatment.bilateral lower extremity doppler study was negative for dvt. stures removed on . dr from neurooncology seen him postop. he will follow him up on in brain tumor clinic along with radiation oncology and dr . pyhiscal therapy consulted for ambulation and need for rehab. pt recommended that patient needs rehab for to regain his strenght to maxiamize his safety at home. discharge medications: 1. bisacodyl 5 mg tablet, delayed release (e.c.) sig: two (2) tablet, delayed release (e.c.) po daily (daily) as needed. 2. atorvastatin calcium 10 mg tablet sig: one (1) tablet po daily (daily). 3. vitamin e 400 unit capsule sig: one (1) capsule po daily (daily). 4. acetaminophen 325 mg tablet sig: 1-2 tablets po q4-6h (every 4 to 6 hours) as needed. 5. docusate sodium 150 mg/15 ml liquid sig: one (1) po bid (2 times a day). 6. metoprolol tartrate 25 mg tablet sig: one (1) tablet po bid (2 times a day). 7. insulin regular human 100 unit/ml solution sig: one (1) injection asdir (as directed): d/c when is off decadron. 8. famotidine 20 mg tablet sig: one (1) tablet po bid (2 times a day). 9. dexamethasone 2 mg tablet sig: one (1) tablet po q12h (every 12 hours). 10. phenytoin sodium extended 100 mg capsule sig: two (2) capsule po bid (2 times a day). discharge disposition: extended care facility: - discharge diagnosis: rigth frontal glioma discharge condition: neurologically stable. discharge instructions: monitor for redness, swelling, darinage. report fever greater than 101, chills, seizure activity or any other neurologic sypmtoms. fluid restrict 1000ml/24 hours until na level normal.lasr na: 132 (). check na level periodically until normal. followup instructions: follow up with dr and dr in brain clinic on at 1600. brain tumor clinic phone number is . please repeat urine analysis for trace blood, trace keton, trace protein, glucose 250, urobil:12 on . procedure: open biopsy of brain transfusion of platelets diagnoses: unspecified essential hypertension other convulsions pulmonary collapse other and unspecified hyperlipidemia other disorders of neurohypophysis malignant neoplasm of cranial nerves 

Answer: The patient is high likely exposed to
