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: ataxia and dizziness major surgical or invasive procedure: right craniotomy for sdh evacuation (), no complications history of present illness: patient is a very poor historian and largely uncooperative and slightly demented. patient c/o long standing dizzyness, but reportidly has been increasingly ataxic with falls home rn. past medical history: dm (full pmh not known, and patient is unable to relate) social history: patient reports he lives alone, visiting nurse: *hcp is a nephew who lives in . (photocopied hcp form is in chart) *mr. w's friend and his wife have visited him several times here in the hospital. they live nearby , very helpful, concerned. family history: nc physical exam: gen: wd/wn, comfortable, nad. heent: pupils:3 to 2 eoms: intact neck: supple. extrem: warm and well-perfused. neuro: mental status: awake and alert, agitated at times. 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, 3to2 mm bilaterally. visual fields are full to confrontation. iii, iv, vi: extraocular movements intact bilaterally without nystagmus. 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 toes downgoing bilaterally coordination: left ftn dysmetria pertinent results: *** initial ct head on presentation : findings: there is a large mixed-density loculated collection layering over the right frontoparietal convexity measuring up to 20 mm in greatest thickness. mass effect on the subjacent sulci is noted. in addition, there is 9 mm of leftward shift of the normally midline structures. along the inferior aspect of the right frontal convexity, there is a hyperdense component (67 ) measuring 4 mm which likely represents a superimposed more acute hemorrhage. overall, this collection is unchanged over the roughly six hour interval, and no new hemorrhage is identified. there is no evidence of entrapment of the left ventricle. basilar cisterns are preserved and the fourth ventricle is patent. no major vascular territorial infarction. prominent hypodense foci in the right parieto-occipital region and occipital pole likely represent established encephalomalacia related to previous infarcts, perhaps embolic. in the left cerebral hemisphere, there is diffuse prominence of the sulci consistent with parenchymal volume loss, age-appropriate. mild mucosal thickening in the left maxillary sinus. the remainder of visualized paranasal sinuses and mastoid air cells are well aerated. no osseous abnormality is identified. dense calcification of the vertebral and cavernous carotid arteries is noted. impression: no overall short-interval change in large mixed-density collection overlying the right frontoparietal convexity, compatible with acute superimposed on subacute-to-predominantly chronic subdural hematoma causing subfalcine herniation. no new hemorrhage compared to study performed six hours earlier. *** post-operative nchct (after sdh evacuation ): fidnings: there has been interval right frontal craniotomy and evacuation of a mixed density subdural collection. there is a large amount of expected post-surgical pneumocephalus with mass effect on the frontal lobes. there is a linear hyperdensity in the right frontal extra-axial space measuring 4 mm in greatest width and consistent with acute blood products in the surgical bed. bifrontal extra-axial isodense collections remain measuring up to 11 mm on the right, compatible with chronic subdural or csf hygromas. there is interval decreased shift of the normally midline structures leftward which now measures 5 mm compared to 9 mm previously. basilar cisterns are preserved. mucosal thickening in the left maxillary sinus and bilateral ethmoid sinuses is noted. remainder of the visualized paranasal sinuses and mastoid air cells are well aerated. calcification of the vertebral and cavernous carotid arteries is again noted. impression: interval right frontal craniotomy with expected post-surgical change. 4 mm linear rim of hyperdensity in the surgical bed consistent with acute blood products. decreased shift of the normally midline structures leftward now measuring 5 mm compared to 9 mm previously. note on attending review: right parietal and occipital hypodense areas with fluid attenuation representing evolution of the previously noted infarct/insult is again visualized and unchanged.( se 2, im13). moderate amount of pneumocephalus with some mass effect on the frontal lobes. attention on close follow up to exclude tension pneumocephalus. atherosclerotic vascular calcifications are noted in the distal vertebral and internal carotid arteries. *** ecg : probable ectopic atrial rhythm. left axis deviation, likely due to left anterior fascicular block. compared to the previous tracing of the rhythm appears to be coming from a non-sinus origin on the current tracing. the other findings are similar. rate intervals: pr qrs qt/qtc axes:p qrs t 74 110 114 394/ *** cxr (pre-op ): small left retrocardiac atelectasis. mild cardiomegaly. brief hospital course: pt was admitted after c/o dizzyness and ataxia. ct imaging revealed right sided sdh. the pt was unable to consent for himself and family was contact. was brought to the or on . his post operative imaging was stable. his postoperative course was uneventful except for occassional sundowning that responded well to seroquel. geriatrics was consulted for assistance with aggitation and polypharmacy. their recommendations were followed. they recommended also that the pt is not to drive unless cleared by the drivewise program. he advanced in his diet and activity. social work and pt were consulted. he was deemed appropriate for subacute rehab. medications on admission: antivert, metformin, glucophage discharge medications: 1. levetiracetam 500 mg tablet sig: one (1) tablet po bid (2 times a day). 2. heparin (porcine) 5,000 unit/ml solution sig: one (1) injection tid (3 times a day). 3. oxycodone 5 mg tablet sig: .5 tab tablet po q4h (every 4 hours) as needed for pain. 4. acetaminophen 500 mg tablet sig: two (2) tablet po q 8h (every 8 hours): taper to off as clinically indicated. 5. cyanocobalamin (vitamin b-12) 1,000 mcg tablet sig: one (1) tablet po daily (daily). 6. metformin 500 mg tablet sig: one (1) tablet po daily (daily). discharge disposition: extended care facility: life care center of discharge diagnosis: right subdural hematoma
