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 and diplopia major surgical or invasive procedure: cerebral angiogram history of present illness: pt reports being at the gym this afternoon and suddenly heard and felt a behind his eyes. he thinks he lost consciousness. he had sudden onset of headache/blurred and double vision. he did vomit on scene and states "apparently i called my mother because she showed up at the gym, but i don't remember calling her. he currently admits to headache 6 out of 10 and blurred vision. he denies nausea / loss of control of bowel or bladder. past medical history: tbi / pedestrian struck / "life support" x 6 days - isolated head trauma with rehab after hospitalization. migraines depression social history: currently laid off from arbella insurance company. rare etoh, occ. mj use, no tobacco. now lives with parents unemployment. family history: noncontributory physical exam: admission physical exam o: t: af bp: 115/ 55 hr:70 r19 o2sats 100 ra gen: wd/wn, slightly uncomfortable at rest, nad. heent:ncat / no hemotympanum pupils: 3.5 - 2.0 bilaterally eomis neck: slight nuchal rigidity extrem: warm and well-perfused. neuro: mental status: awake and alert, cooperative with exam, normal affect. orientation: oriented to person, place, and date. language: speech fluent with good comprehension and repetition. naming intact. no dysarthria or paraphasic errors. cranial nerves: i: not tested ii: pupils equally round and reactive to light,2.5 to 2.0 mm bilaterally. visual fields are full to confrontation. iii, iv, vi: extraocular movements intact bilaterally without nystagmus. (closes right eye as if to correct for diplopia - however no diplopia noted on exam) v, vii: facial strength and sensation intact and symmetric. viii: hearing intact to voice. 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 discharge physical exam: alert and oriented x3 continues to have some double vision cn 2-12 grossly intact motor exam full throughout pertinent results: ct/cta head : c- head: focal parenchymal hemorrhage originating from the posterior midbrain/pons and extending into the ventricular system, filling the 4th ventricle with mild dilatation of the lateral ventricles. cta: increased vessels appearing to supply and drain the region of the parenchymal bleed, suggesting avm. no aneurysm or occlusion. ct head 1. intraventricular hemorrhage centered in the fourth ventricle with extension into the third ventricle and to the level of foramen of and extension through foramen of magendie and luschka with hemorrhage surrounding the cervical cord, with no significant interval change. ventricles are stable. 2. stable areas of encephalomalacia involving the frontal lobes and to a lesser extent the temporal tips likely representing a sequela of prior trauma. ______________________________________________________________ , m 36 non-contrast head ct: as compared to the prior scan from , , there has been increase in size of lateral ventricle and third ventricle compatible with mild-to-moderate hydrocephalus. there has been interval decrease in intraventricular blood with small amount of bleeding within the fourth ventricle as well as intraparenchymal bleed within the posterior . mastoid air cells are clear. impression: 1. new mild-to-moderate hydrocephalus. no new areas of intracranial hemorrhage. 2. intraparenchymal hemorrhage at posterior midbrain extending to the fourth ventricle and the spinal canal has decreased since prior exam. 3. stable bilateral frontal and temporal encephalomalacia, likely representing sequelae of prior trauma. brief hospital course: 36 y/o male with history of tbi in , presents to the ed after working out at the gym. he states that he felt a popping sensation behind his eyes. he does not recall all the events that took place, but his mom was present to transport the patient to the ed. on his way to the ed, the patient was expreincing n/v. head ct revealed an isolated third ventricle hemorrhage. patient was nonfocal except for r diplopia. he was admitted to neurosurgery. on , patient was takem for a diagnostic angiogram. no avm or aneurysm was found on angiogram and patient remained in the icu. his exam was stable. patient was then transferred to step down unit with a neuro-optho consult for r diplopia and repeat head ct. neuro optho recommendation were to not patch the eye and observe the patient. he should follow up in the clinic after discharge. he was also found to have a cranial nerve iv paresis which was not unusual. repeat head ct was stable. a neurology consult was needed to help determine the etiology of his hemorrhage. he remained stable until on he had a ct scan that showed hydrocephalus. he was slightly lethargic that am and therefore transferred back to the icu for close observation. his subsequent imaging was stable, and he slowly began to accomidate his hydrocephalus and reached his baseline mental status and was transferred to the floor. prior to discharge he was seen and cleared by physical therapy. an mri/mra of the brain was also performed which showed no evidence of an underlying vascular lesion. medications on admission: none 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. butalbital-acetaminophen-caff 50-325-40 mg tablet sig: tablets po 4-6hrs prn as needed for headache. disp:*60 tablet(s)* refills:*0* discharge disposition: home discharge diagnosis: intraventricular hemorrhage discharge condition: improved discharge instructions: angiogram: medications: ?????? continue all other medications you were taking before surgery, unless otherwise directed ?????? you make take tylenol or prescribed pain medications for any post procedure pain or discomfort. what activities you can and cannot do: ?????? when you go home, you may walk and go up and down stairs. ?????? you may shower ?????? your incision may be left uncovered, unless you have small amounts of drainage from the wound, then place a dry dressing or band aid over the area that is draining, as needed ?????? no heavy lifting, pushing or pulling (greater than 5 lbs) for 1 week (to allow groin puncture to heal). ?????? after 1 week, you may resume sexual activity. ?????? after 1 week, gradually increase your activities and distance walked as you can tolerate. ?????? no driving until you are cleared to by the medical team what to report to office: ?????? changes in vision (loss of vision, blurring, double vision, half vision) ?????? slurring of speech or difficulty finding correct words to use ?????? severe headache or worsening headache not controlled by pain medication ?????? a sudden change in the ability to move or use your arm or leg or the ability to feel your arm or leg ?????? trouble swallowing, breathing, or talking ?????? numbness, coldness or pain in lower extremities ?????? temperature greater than 101.5f for 24 hours ?????? new or increased drainage from incision or white, yellow or green drainage from incisions ?????? bleeding from groin puncture site *sudden, severe bleeding or swelling (groin puncture site) lie down, keep leg straight and have someone apply firm pressure to area for 10 minutes. if bleeding stops, call our office. if bleeding does not stop, call 911 for transfer to closest emergency room! followup instructions: please call the office at to be seen by dr. in 4 weeks. you will need an angiogram at that time. neuropsych: call dr. for follow up at ( ophthomology: f/u in clinic - please call for an appointment to be seen when you get home. procedure: arteriography of cerebral arteries diagnoses: obstructive hydrocephalus depressive disorder, not elsewhere classified intracerebral hemorrhage migraine, unspecified, without mention of intractable migraine without mention of status migrainosus diplopia fourth or trochlear nerve palsy 

Answer: The patient is high likely exposed to
