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: weakness major surgical or invasive procedure: right suboccipital craniectomy with decompression placement evd transesophogeal echocardiogram history of present illness: hpi: patient is a 46 yo man with history of obesity who who presented to medical center with complaint of several days weakness, fatigue and falls. he had been feeling unwell for about three weeks and had been falling out of bed in the mornings. he was unable to stand am and father called ems. progressive weakness and lethargy for 3 weeks according to family. had a head ct at 21:22 showing cerebellar mass. mri was performed this afternoon and showed large right cerebellar mass with areas of hemorrhage, significant mass effect and associated hydrocephalus. report describes near effacement of the 4th ventricle and mass effect on the brain stem. there is striated enhancement of the lesion with the mass measuring 6.2 x 5.4 cm. past medical history: none social history: social hx: recently unemployed from computer work. positive tox for marajuana, no tob. occasionaly etoh. family history: family hx: mother had stroke late in age. father alive with htn, pvd and dm. physical exam: physical exam: o: t: 98.9 bp: 164/95 hr: 76 r 17 o2sats 99 vented gen: intubated, sedation with propofol just turned off heent: pupils: bilaterally eoms: absent with doll's maneuver neck: supple. lungs: cta bilaterally. cardiac: rrr. s1/s2. abd: soft, nt, bs+ extrem: warm and well-perfused. neuro: mental status: unresponsive to voice. moves x 4 to noxious stimulation. does not follow commands. eyes closed. cranial nerves: i: not tested ii: pupils equally round and reactive to light, 3 to 2 mm bilaterally. no blink to threat. iii, iv, vi: extraocular movements absent with doll's manevuer. eyes midline. v, vii: face symmetric. corneals absent bilaterally. viii: unresponsive ix, x: weak gag to suction. : sternocleidomastoid and trapezius normal bilaterally. xii: tongue midline without fasciculations. motor: normal bulk and tone bilaterally. no abnormal movements, tremors. antigravity x 4 to noxious stim and symmetric. sensation: withdraws x 4. reflexes: b t br pa ac right 0 0 0 0 0 left 0 0 0 0 0 toes upgoing bilaterally coordination: could not assess physical exam on discharge: a&ox3 pupils: 3-2mm bilaterally face symmetrical tongue midline slight l pronator drift motor: throughout incision: c/d/i pertinent results: labs: 138 105 15 agap=14 ------------< 323 4.3 23 1.0 ca: 8.5 mg: 2.2 p: 3.4 12.8 10.0 >< 235 38.8 ct/mri: mri from osh shows: large right cerebellar mas with areas of hemorrhage, significant mass effect and associated hydrocephalus. report describes near effacement of the 4th ventricle and mass effect on the brain stem. there is striated enhancement of the lesion with the mass measuring 6.2 x 5.4 cm. brief hospital course: pt was admitted to the hospital on neurosurgery service to icu for close neurologic monitoring. he had placement of evd with normal icps. he was readied for the or including mri wand study and on went to or where under general anesthesia he underwent right suboccipital craniectomy with excision of necrotic brain from infarct. he tolerated this procedure well, remained intubated and transferred back to icu. post op ct showed good decompression without new hemorrhage. his evd continued to function and was clamped on pod#2 and removed the next day. he was extubated on pod#2 and tolerated this well although did have issues with sleep apnea requiring cpap. his neurologic exam improved and he was following commands, conversant and full motor exam. his incision was clean and dry with staples. he was seen in consultation by the stroke neurolgy team. he underwent tte which showed no vegetations and he underwent tee which showed a pfo which will be followed up as an out patient by neurology. cta of head and neck revealed no evidence of stenosis in the carotid or vertebral arteries. he was transferred to stepdown pod#4 and diet and activity were advanced. he was started on steroids for cerebral edema and these were weaned down post op; pt had elevated glucose and found to have hga1c of 11.9 and seen in consultation by the team for insulin management. he had pt/ot evaluations that felt he was approprite for discharge to home. diabetes teaching was done by nursing. he was refusing vs and lab work. he verbalized refusal to use cpap at home. he was discharged to home with prescriptions for the next several days as well as prescriptions for his ongoing needs to bring to the free care clinic during the week. medications on admission: home meds: none medications at transfer: fentanyl gtt, versed, propofol,nitropaste, lopressor iv, riss, asa 325 daily, lorazepam 1mg q2hrs prn, nexium 40mg daily, heparin 5000 sc q12, riss, colace,acetaminophen discharge medications: 1. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 2. glucagon (human recombinant) 1 mg recon soln sig: one (1) recon soln injection q15min () as needed for hypoglycemia protocol. 3. simvastatin 40 mg tablet sig: two (2) tablet po daily (daily). 4. aspirin 81 mg tablet, chewable sig: one (1) tablet, chewable po daily (daily). 5. famotidine 20 mg tablet sig: one (1) tablet po bid (2 times a day). 6. metformin 500 mg tablet sustained release 24 hr sig: one (1) tablet sustained release 24 hr po bid (2 times a day). 7. dilaudid 2 mg tablet sig: 1-2 tablets po q6h prn as needed for pain. disp:*40 tablet(s)* refills:*0* discharge disposition: home discharge diagnosis: right cerebellar infarct newly diagnosed diabetic obstructive hydrocephalus obstructive airway disease morbid obesity discharge condition: neurologically stable discharge instructions: discharge instructions for craniotomy/head injury ?????? have a family member check your incision daily for signs of infection ?????? take your pain medicine as prescribed ?????? exercise should be limited to walking;
