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: erythromycin base attending: chief complaint: imbalance and visual problems major surgical or invasive procedure: none history of present illness: this is a 34 year old man who felt ill several nights prior to presentation. he went to bed early and awoke with difficulty with vision when eyes open. he denies headache, nausea, vomiting, weakness past medical history: pneumonia several years ago social history: married, no children. works as software engineer. no tobacco, no etoh, no illicits. family history: mother's brother had unusual neurologic condition that led to death in his 50's. no history of brain hemorrhage or tumor. physical exam: gen: wd/wn, comfortable, nad. heent: nc/at neck: supple. extrem: warm and well-perfused. neuro: mental status: awake and alert, cooperative with exam, normal affect, keeps eyes closed during exam orientation: oriented to person, place, and date. recall: objects at 5 minutes. 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, 5 to 4 mm bilaterally. visual fields are full to confrontation. iii, iv, vi: extraocular movements intact bilaterally with nystagmus bilaterally. 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 sensation: intact to light touch, propioception, pinprick and vibration bilaterally. coordination: finger-nose-finger slightly dysmetric on left, heel to shin also decreased coordination on left pertinent results: mri 1. right cerebellar acute hemorrhage measuring 16 x 14 mm with mild surrounding edema and mass effect on the fourth ventricle. 2. in association with the adjacent developmental venous anomaly and additional area of susceptibility in the right centrum semiovale, the hemorrhage likely is related to a cavernous malformation. no definitely enlarged arterial or venous structures are seen to indicate underlying arteriovenous malformation. followup study can help for further assessment if clinically indicated. ct unchanged appearance of right cerebellar intraparenchymal hemorrhage with surrounding edema; prior mr suggested the underlying lesion may be a cavernous malformation and is better characterized on that study. angio right common carotid artery arteriogram shows no evidence of stenosis at the right common carotid artery bifurcation. right external carotid artery arteriogram shows no evidence of dural av fistula. the right occipital artery is seen to be fairly large and has extensive arborization. there is a large suboccipital cavernous plexus of veins. right internal carotid artery arteriogram shows that the right internal carotid artery fills well along the cervical, petrous, cavernous and supraclinoid portion. the anterior and middle cerebral arteries are seen well with no evidence of aneurysms or arteriovenous malformations. left vertebral artery arteriogram shows filling of the left vertebral artery and the basilar artery with reflux into the right vertebral artery. both posterior cerebral arteries are seen well. both superior cerebellar arteries are seen well. no aneurysms are seen. there is no evidence of dural av fistula. left common carotid artery bifurcation shows no evidence of stenosis. left internal carotid artery arteriogram shows that the left internal carotid artery fills well along the cervical, petrous, cavernous and supraclinoid portion. the anterior and middle cerebral arteries are seen well with no evidence of aneurysms or arteriovenous malformation. the posterior communicating artery is seen with flash filling of the right posterior cerebral artery. left external carotid artery arteriogram shows no evidence of dural av fistula. right common femoral artery arteriogram shows widely patent right common femoral artery brief hospital course: patient presented to with 2 days of visual changes and blurry vision. a ct scan showed a right cerebellar bleed versus cavernous malformation. on he had a stable nchct however hius dizziness increased. his dizziness continued to increase on and a stat head ct was obtained which was stable. on he underwent a conventional cerebral angiogram which revealed no definitive source for his hemorrhage. on and he was stable and on he was transferred to the floor for further care. he was started on meclizine and valium with good effect. on he worked with pt and on 3.5 was cleared for home with outpatient pt. he was discharged with instructions for follow-up medications on admission: none discharge medications: 1. acetaminophen 325 mg tablet sig: 1-2 tablets po q6h (every 6 hours) as needed for fever,ha: max apap 4g/24 hrs. 2. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 3. hydralazine 25 mg tablet sig: one (1) tablet po q6h (every 6 hours). 4. famotidine 20 mg tablet sig: one (1) tablet po bid (2 times a day). 5. diazepam 2 mg tablet sig: one (1) tablet po q6h (every 6 hours) as needed for anxiety. disp:*60 tablet(s)* refills:*0* 6. meclizine 12.5 mg tablet sig: two (2) tablet po bid (2 times a day). disp:*120 tablet(s)* refills:*2* discharge disposition: home discharge diagnosis: right cerebellar hemorrhage cavernous malformation discharge condition: mental status: clear and coherent. level of consciousness: alert and interactive. activity status: ambulatory - requires assistance or aid (walker or cane). discharge instructions: 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 (let the soapy water run over groin incision, rinse and pat dry) ?????? 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 no longer taking pain medications what to report to office: ??????

?????? 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

Answer: The patient is high likely exposed to
