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: evaluate patient for ivh major surgical or invasive procedure: cerebral angiogram bifrontal craniotomy and excision of arteriovenous malformation history of present illness: pt is a 51 year-old male found by a friend to be incoherent and confused. apparently the patient had been out of touch for several days so his friend went looking for him. the patient is awake and speaks in sentences that make sense but the story itself makes no sense. he states that he has had a headache for a year. he is not sure if he got hit. the patient admits to recent cocaine use but not iv drugs. he was brought to an osh er where a ct scan showed blood in the lateral ventricles l > r, third ventricle, and fourth ventricle. he was then transferred to for further management. past medical history: substance abuse, otherwise unclear. social history: social hx: claims to own an autobody shop. he drinks 4 vodka cocktails/day. family history: family hx: nc physical exam: physical exam: vitals: t: 98.9 p: 72 r: 16 bp: 146/96 sao2: 98% ra general: drowsy but arousable, opens eyes, answers questions heent: ncat neck: no meningismus pulmonary: lungs cta bilaterally without r/r/w cardiac: nl. s1s2 abdomen: soft, nt, mild tenderness in the epigastrium to palpation but no rebound or guarding extremities: no edema neurologic: -mental status: drowsy but answers all questions. knows name but does not know date or hospital. fluent speech but easily distracted. follows simple commands. cranial nerves: i: not tested ii: perrl, 4-->2mm with light. iii, iv, vi: eomi. no nystagmus. v, vii: facial sensation intact, facial strength viii: hearing intact b/l to finger rubbing. ix, x: palatal elevation symmetrical. : scm xii: tongue midline without fasciculations. pertinent results: 08:25pm blood wbc-10.4 rbc-4.26* hgb-13.6* hct-37.1* mcv-87 mch-32.0 mchc-36.7* rdw-13.4 plt ct-233 08:25pm blood neuts-55.0 lymphs-38.7 monos-4.2 eos-1.5 baso-0.6 08:25pm blood pt-14.0* ptt-25.2 inr(pt)-1.2* 08:25pm blood glucose-98 urean-26* creat-0.9 na-139 k-3.6 cl-101 hco3-28 angap-14 08:25pm blood alt-42* ast-32 ld(ldh)-149 alkphos-76 amylase-147* totbili-0.6 cta: the cta examination demonstrates no evidence of aneurysm formation. however, there is a prominent vein just to the right of midline in the right frontal lobe. although this could represent a developmental venous anomaly, it is suspicious for a vein draining a small arteriovenous malformation. impression: 1. no evidence of new hemorrhage. 2. persistent but evolving corpus callosum and intraventricular hemorrhage. 3. avm in the pericallosal region on the right and nonvisualization of right a1, otherwise normal cta of the head. brief hospital course: pt was brought for cerebral angiogram for avm intervention however this was not possible. he was then taken to the or on for bifrontal crani and avm resection. he was delerious for approximately 24hrs post-op however with psychiatry input he returned to his baseline prior to surgery which was a&ox1-2 and full strength. he was then admitted to the icu where he continued to improve he was transferred to the floor on . the remainder of his hospital stay surrounded finding suitable discharge placement for mr . pt/ot and speech therapy found him to the patient demonstrated reduced sustained attention and attentional fluctuations throughout the examination. he was easily distracted by environmental noises and test performance was negatively impacted when there was any extraneous noise in the room. his digit span was reduced at four numbers forward, demonstrating deficits in working memory. he recalled presented words after 5 minutes, 0/3 after 10 minutes and 0/3 after 20 minutes. semantic cues were mildly beneficial for recall. it appears that new learning is impaired for both encoding and recall. the patient demonstrates significant deficits in recall of general information. for example, the patient was unable to generate the current governor, state capitol, or first president. he was also unable to name the state in which he resides or any city on the east coast. in regards to executive functioning, the patient demonstrated significantly impaired insight into his deficits. he stated that he knew he had "problems" but was unable to elaborate what his deficits are or their impact on his ability to work. when he erroneously answered a question, he frequently stated, "i would never have known that!" organization and planning were also impaired. problem solving and abstract reasoning were significantly impaired. many responses to questions were delayed, incomplete or confabulatory in nature. for example, when asked how a watch and a calendar are different he concretely responded "one you wind up and one you rear off." physically he had no motor deficts, he was tolerating a regular diet and ambulating without difficulty. medications on admission: street drugs discharge disposition: extended care facility: discharge diagnosis: avm discharge condition: neurologically stable discharge instructions:
