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: -dur attending: chief complaint: elective admission for left temporal lobectomy major surgical or invasive procedure: l craniotomy for resection of mass l temporal lobectomy history of present illness: 81m with hx of left parotid cancer treated with radiation in who now presents with increased confusion and concern for progression of radiation necrosis. in , the patient had an mri that showed a left temporal lobe lesion. this was felt to be most consistent with radiation necrosis on review by neuro here at and the patient was started on steroids at that time. he had improvement and had no further issues until recently his family noted new behavioral changes. the family noticed the confusion 1 year ago with occasional combativeness. however, the patient was still able to be very independent, including driving. he had been seen by his pcp and neurologist over this past year who started him on anti-depressant medications (initially citalopram, then switched to fluoxetine). 2 months ago, the patient had a more rapid decline with respect to confusion and behavior and family stopped letting him drive. he was seen back in clinic with dr. on - he recommended repeat imaging with pet-ct and mri. the repeat mri showed a new complex mass in the temporal lobe with the read saying most consistent with persistent radiation necrosis. he was started on high dose steroids at that time with dexamethasone 12mg daily although became quite combative at that dose. his dose was then tapered to 4mg which helped with the combativeness however he was still very confused and weak and was admitted by dr for further workup. while in house he was started on insulin and ultimately discharged home with plans for follow-up with us. today he presents to the clinic to discuss possible surgical intervention. since discharge he has had issues with his blood sugars and also had a fall on new years eve after which he had a laceration on his right eye brow requiring stitches. past medical history: past oncologic history: left facial nerve palsy and left cheek lesion mri showed left parotid mass left total parotidectomy, left facial nerve resection and greater auricular nerve graft, scm flap, gold weight impland to left upper lid, tarsal strip blepharoplasty of the left lower lid by dr. at pathology: high grade muco-epidermoid carcinoma with perineural invasion, level 2 ln negative fna of neck ln, suspicious for carcinoma - xrt in 35 fr. by dr. neck mri showed left temporal brain lesion brain mri showed left temporal lesion brain mri

considered multi-infarct dementia 18. low vitamin b12 19. prostatism social history: he is widowed and lives alone, but his daughter lives upstairs in the same building. his parents are deceased. he has no siblings. he had five children, one died in a motorcycle accident. among his children, is the health care proxy. is a retired machinist. he smoked for 20 years. family history: uncle with parotid ca. physical exam: gen: wd/wn, comfortable, nad. heent: stitches over right eyebrow from fall pupils: perrl eoms intact neck: supple. lungs: cta bilaterally. cardiac: rrr. s1/s2. abd: soft, nt, bs+ extrem: warm and well-perfused. no c/c/e. neuro: mental status: awake and alert, cooperative with exam, normal affect. orientation: oriented to person and place language: speech fluent with moderately good comprehension cranial nerves: i: not tested ii: pupils equally round and reactive to light, 4mm to 3mm bilaterally. visual fields are full to confrontation. iii, iv, vi: extraocular movements intact bilaterally without nystagmus. v, vii: left facial droop, decreased sensation of left cheek secondary to radiation. viii: hearing decreased on left ix, x: palatal elevation symmetrical. : sternocleidomastoid and trapezius normal bilaterally. xii: tongue midline without fasciculations. motor: normal bulk and tone bilaterally. no abnormal movements, tremors. strength full power throughout. no pronator drift sensation: decreased left side of face toes downgoing bilaterally coordination: right dysmetria pertinent results: ct head w/o contrast 1.immediately status post left temporparietal craniotomy and resection of mass in the left temporal lobe, with expected post-surgical change 2. hyperdensity in the extra-axial space overlying the left frontal lobe, new, likely small subdural hemorrhage. 3. extensive vasogenic edema with leftward shift of normally-midline structures, slightly more pronounced compared to the examination mri brain with and without contrast : findings: the patient is status post left temporoparietal craniotomy with expected post-surgical changes in the form of pneumocephalus, left frontal extra-axial fluid collection (measuring 6 mm in maximal thickness) and large fluid-filled resection cavity at the tip of the left temporal lobe with sedimentation and fluid-fluid level. a considerable amount of blood product is lining the posterior and medial aspect of the resection cavity. enhancement is noted along the dura and is likely reactive in nature. on diffusion-weighted images, there is gyriform hyperintensity on the dwi (images # 12,13,14, series #9), involving the posterior aspect of the resection cavity and extending along the primary auditory associative cortex, concerning for acute/subacute areas of ischemia. the previously reported vasogenic edema, involving the left temporal and the left parietal lobe is unchanged, there is stable mass effect with distortion of the lateral ventricles, compression of the left cerebral peduncle and midline shift. flow voids of the major intracranial vessels are preserved. the paranasal sinuses are clear. opacification of the left mastoid air cell is largely unchanged. impression: 1. status post resection of right temporal lesion with postoperative changes in the form of dural enhancement extra-axial fluid (6 mm in maximal thickness), pneumocephalus, and moderate hemorrhage at the resection site. 2. gyriform hyperintensity on the dwi (images # 12,13,14, series #9), involving the posterior aspect of the resection cavity and extending along the primary auditory associative cortex, concerning for acute/subacute areas of ischemia. head ct w/o contrast : findings: status post left temporoparietal craniotomy, resection of the left temporal complex lesion with persistent extensive vasogenic edema with effacement of the left lateral ventricle. however, there is a new large hemorrhage in the resection site spanning over area of 5.5 x 4.7 cm. there is also increase in the subdural hemorrhage along the falx (2:17) and tracking along the left convexity. there is increase in the rightward shift of midline structures from 4.5-8 mm in keeping with increased mass effect from the new hemorrhage. there are areas of attenuation in the subcortical and periventricular white matter, likely chronic small vessel ischemic changes. there is residual post-surgical left pneumocephalus. impression: status post left temporoparietal craniotomy and resection of left temporal lobe lesion with a new large intraparenchymal hemorrhage at the resection site and interval increase in size of left extra-axial subdural hematoma. interval increase in mass effect and shift of midline structures from 4.5-8 mm. head ct w/o contrast : status post left temporoparietal craniotomy and resection of left temporal lobe lesion with interval increase in large intraparenchymal hemorrhage at the resection site and interval increase in laryering bld in right ventricle. again noted is left extra-axial subdural hematoma. interval increase in mass effect and max rightward shift of midline structures measured as 11.2mm compared to 8mm. brief hospital course: 81 y/o m with history of parotid ca presents with increased confusion. mri head revealed a l temporal lobe lesion. patient was admitted on for elective resection and temporal lobectomy for tumor necrosis. on , patient was taken to the or with an uncomplicated course. he was taken to the icu for close monitoring post operatively. post op head ct revealed some pneumocephalus and stable midline shift. on examination, patient remained at baseline. on , he was stable and encourgaed to be oob with assistance. he is scheduled for an mri of the head and then will be transferred to the floor. his dexamethasone was also weaned to a qod taper. on he was grossly stable in the stepdown unit while awaiting evaluation by pt and ot for disposition planning. in the afternoon, it was noted that he had a mental status change- nonverbal, lethargic, asymmetric pupils. a stat head ct was done which showed hemorrhage into the surgical cavity with midline shift. he was transferred to the icu. a repeat head ct showed worsening midline shift. a meeting was had with the family and it was decided to not pursue aggressive intervention. he was made dnr/dni/cmo. all medications were discontinued except for those promoting comfort. on at 4:40 pm the patient expired and was pronounced by dr. (note in omr). medications on admission: 1. alprazolam 0.25 mg by mouth once a day 2. baclofen 5 mg by mouth 3 times per day for hiccups 3. clopidogrel 75 mg by mouth once a day 4. dexamethasone 6 mg by mouth twice a day 5. fexofenadine 60 mg by mouth as needed 6. fluoxetine 20 mg by mouth once a day 7. lorazepam 1 mg by mouth at bedtime 8. omeprazole 20 mg by mouth daily 9. primidone 50 mg by mouth twice a day 10. simvastatin 20 mg by mouth at bedtime 11. tamsulosin 0.4 mg by mouth at bedtime 12. cholecalciferol 2,000 unit by mouth once a day discharge disposition: expired discharge diagnosis: l temporal lobe lesion/tumor necrosis l temporal ich with midline shift cerebral edema discharge condition: xx discharge instructions: xx xx followup instructions: xx procedure: arterial catheterization other repair of cerebral meninges operations on two or more extraocular muscles involving temporary detachment from globe, one or both eyes lobectomy of brain diagnoses: coronary atherosclerosis of native coronary artery diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled asthma, unspecified type, unspecified personal history of tobacco use depressive disorder, not elsewhere classified hypertrophy (benign) of prostate without urinary obstruction and other lower urinary tract symptom (luts) intracerebral hemorrhage other b-complex deficiencies other and unspecified hyperlipidemia long-term (current) use of insulin cerebral edema osteoarthrosis, unspecified whether generalized or localized, site unspecified bell's palsy encounter for palliative care do not resuscitate status accidents occurring in residential institution removal of other organ (partial) (total) causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation vascular dementia, uncomplicated cerebral atherosclerosis iatrogenic cerebrovascular infarction or hemorrhage radiological procedure and radiotherapy as the cause of abnormal reaction of patient, or of later complication, without mention of misadventure at time of procedure unspecified diseases of blood and blood-forming organs other conditions of brain personal history of malignant neoplasm of other and unspecified oral cavity and pharynx abnormal involuntary movements cerebral cysts other chronic otitis externa
