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: headache major surgical or invasive procedure: cerebral angiogram external ventricular drain history of present illness: pt is 53 y/o healthy m who presents with severe global headache with onset at 4 pm today. pt stated that he had just finished working on his truck at the time. he describes the headache as throbbing and is accompanied by dizziness. pt states that his vision from both eyes gets blurry at times. when pt developed his headache, he laid himself into his car, but was able to walk and find his wife who took him to the hospital. at osh, pt had a non-contrast head ct scan which showed a left sided sah. pt was transferred to for further management. past medical

cta head neck : 1. large anterior communicating artery aneurysm whose rupture appears to be the cause of the increasing subarachnoid hemorrhage noted within the brain, compared to the prior non-contrast head ct. 2. markedly narrow a1 segment of the right anterior cerebral artery may be due to congenital hypoplasia or less likely due to spasm (given time duration). ct head : 1. redemonstration of extensive subarachnoid hemorrhage, as described above. of note, there is increased blood seen layering within the occipital horns of the lateral ventricles. 2. interval placement of a right frontal approach ventriculostomy catheter, terminating in the left lateral ventricle. 3. new aneurysm coils in the region of the anterior communicating artery. 4. stable hydrocephalus. ct head : the patient is status post aneurysm coiling in the vascular territory of the anterior communicating artery, unchanged subarachnoid hemorrhage and intraventricular hemorrhage with ventricular shunt via right frontal burr hole, the tip terminating on the left ventricular as described above. there is no significant change in the size and configuration of the ventricles since the prior study. no evidence of low attenuation areas or significant edema to indicate subacute ischemic changes. the cta demonstrates persistent lobulated aspect of the aneurysm in the superior dome with no significant change since the prior cerebral angiogram, and coil embolization. these findings were discussed with dr. on at 12:10 hrs. again hypoplasia of the a1 segment is redemonstrated, both anterior cerebral arteries are filling from the left. no flow-stenotic lesions are identified or vasospasm. cta head : the patient is status post aneurysm coiling in the vascular territory of the anterior communicating

no intracranial hemorrhage. 2. interval improvement of the vasospasm involving the left middle cerebral artery, anterior cerebral arteries, posterior cerebral arteries, and basilar artery. 3. unchanged residual aneurysm filling at the base of the coil pack of the anterior communicating artery aneurysm. brief hospital course: patient presented on with severe headache and dizziness after working on his truck. he also reported some blurred vision. his wife took him to where a was performed and found a left side sah. patient was then sent for a cta where an acom aneurysm was found. patient became lethargic and less responsive, angiogram was performed to coil aneurysm and an evd was placed to relieve icp. his drain was leveled at 15 and was observed to be draining well. post angiogram check it was noted that patient was moving his l>r. cta/p was ordered and was stable. he was then extubated. on , his exam improved, he was a&ox3, full strength on l and antigravity with both upper and lower extremities on the r side. on , patient continues to be alert and oriented x3 and full strength on l. rue remains antigravity and rle, he is only able to wiggle toes. he was taken to angiogram where mild vasospasm was seen and he received 10mg of verapamil intrathecally. his sbp will be pushed to 180 and we will repeat angio on . in the afternoon, patient failed a clamping trial and drain was reopened to relieve icp. overnight the drain was observed to be draining less and a poor waveform was also noted. the drain was flushed with normal saline, but continued to have poor waveform and ouptut. tpa was administered to flush the drain proximally. patient remains stable. overnight he also had a tmax of 101.9, he was pancultured and a cxr was ordered. csf samples have been negative to this date. over the weekend of and , the patient's blood pressure was liberalized by the sicu team to less than 140. the patient subsequently had a change in his neurological status. he had mental status changes and no command following. a stat head ct/cta was performed , which showed persistent but not new vasospasm. he was kept at a strict 160-180 following this incident. he was started on a 3% hts for chronic hyponatremia (na 12) at 10cc an hour, titrating up to 30cc/hour. on , patient's blood pressure was liberalized to 140-160. cta on showed vasospasm and hypertonic saline is being weaned to off. mri of the lumbar spine was ordered due to patient's complaint of back pain. mri results show some sah blood within the thecal sac. it also showed an intradural hematoma at l2 with mild cord compression. evd still in place at 20 and open to drainage. on overnight patient became confused, but over time began to was more alert and oriented. drain was sluggish and was flushed x2 in am. blood pressure parameters continue to be 140-160. patient was taken to angiogram where he was seen to be in vasospasm and treated with verapamil. we continue to keep his pressures between 140-160. there was a question of seizure activity and patient was then transitioned to keppra from dilantin. on , patient was stable and his evd was removed. he has episodes where he does not speak, but will after constant prompting. he also spiked fevers 103 and was pancultured. lenis showed a r dvt from the proximal sfv. cta of chest showed a r subsegmental pe. heparin gtt was started with a goal ptt 40-60. an ivc filter was also placed. patient was observed to have rue weakness which was improved on and ssri restarted for his depression. his neurological exam improved and his blood pressure remained well controlled; therefore he was transferred out of the icu to the floor on . patient's neurologic exam continued to improved, rle in ips and rue 5-/5. cta was done on which was stable and patient was taken to angiogram for coiling of his aneurysm. his angiogram and coiling was completed without difficulty and he was placed on a heparin gtt overnight which was stopped on the morning of . on he was transferred to the floor and subcutaneous heparin was restarted. he remained stable on the floor and on was deemed fit to be discharged to rehab. medications on admission: mvi
