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: no known allergies / adverse drug reactions attending: chief complaint: headache while sitting on the couch major surgical or invasive procedure: : cardioversion : embolization of avm : ablation of a-flutter history of present illness: asked by the neurology service to see this gentleman for evaluation and possible angiogram. mr. is a right handed 63 yo m with hx parathyroid adenoma that was here transferred from osh with a r occipital hemorrhage on . he presented a history of developing a headache while sitting on the couch at 10:45 am he developed a severe right temporal headache then moving toward his occiput. pain waxed and waned and was able to ambulate during this. he looked at a picture on his wall and noticed the left side was missing and went to . upon arrival to osh he was found to be in atrial flutter with bp 161/128. ct head showed a large right occipital iph and was given fosphenytoin, ativan, started on a dilt drip and transferred here. past medical history: -parathyroid adenoma -prior trauma to r eye social history: -lives with wife, no tobacco, occasional wine family history: -no history of strokes or hemorrhages physical exam: o: t: bp:112 /89 hr:125 r 16 o2sats 93 gen: wd/wn, comfortable, nad. heent: ncnt neck: supple. lungs: cta bilaterally. cardiac: rrr. s1/s2. abd: soft, nt, bs+ extrem: warm and well-perfused. neuro: mental status: awake and alert, cooperative with exam, normal affect. 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,4 to 3 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, proprioception, pinprick and vibration bilaterally. coordination: normal on finger-nose-finger on fisharge he has a non focal neurological exam with persistent decreased vision to left eye. pertinent results: ct head w/o contrast study date of 5:28 pm 1. essentially unchanged large right occipital lobe intraparenchymal hemorrhage, with mild mass effect in the adjacent parenchyma but no gross midline shift. differential diagnosis consideration for acute intraparenchymal hemorrhage includes hypertension, underlying brain lesion, avm, or amyloid angiopathy. 2. no intraventricular hemorrhagic extension. no new foci of hemorrhage. no developing hydrocephalus. cta head w&w/o c & recons 1. right occipital intraparenchymal hemorrhage with mild surrounding edema. 2. findings on ct angiography of the head suggest a most likely an arteriovenous malformation in the region of hemorrhage within tortuous arterial structures supplying the region with a 5-mm density could represent compressed nidus or venous aneurysm. draining vein is also visualized. no other vascular abnormalities. ct head w/o contrast 1. unchanged size of the right occipital intraparenchymal hemorrhage, and surrounding edema, and minimal mass effect on the adjacent occipital of the right lateral ventricle. 2. extensive paranasal mucosal thickening and opacification of mastoid air cells bilaterally could represent an ongoing inflammatory process. ct head w/o contrast : no significant interval change. similar size of right occipital intraparenchymal hemorrhage and surrounding edema with a similar mass effect on occipital of right lateral ventricle. brief hospital course: 63m initially presented to osh with r temporal/occipital headache. at osh, cth showed 5 x 2.5cm right occipital bleed. he also was noted to go into aflutter with rvr and was started on diltiazem gtt. upon txfer to , he was noted to have a left facial droop with good motor strength throughout. repeat head ct showed that the hemorrhage had grown to 4 x 2.3cm with edema but no midline shift. he was admitted to stroke neurology/ neuro-icu. on he had aflutter with rvr and he received a amio , aline was placed, and he received metoprolol 5mg iv x 2. metoprolol po was started. a tte showed an ef >75% and impaired relaxation. on he was tachycardiac, cardiac enzymes were sent but negative. digoxin was started and metoprolol was increased. a cta was performed which showed an underlying avm. on he continued to have aflutter with rvr and cardiology was consulted. the patient was given lasix, ibutilide, verapamil, lopressor, and digoxin. he was made npo at midnight for possible tee and cardioversion. on he underwent a tee which showed no clot and then underwent cardioversion into normal sinus rhythm. he remained stable and on he underwent a angiogram for embolization of the avm. post-embolization, he was transferred to neurosurgery and remained in the neuro-icu for observation. post-embolization, his sbp was kept below 110, this was acheived with labetolol iv prn, no drip was required. on he remained stable and visual fields appeared improved, his sbp was liberalized to 160. he was written for sdu transfer but no beds were available and he was kept in the icu. on , he was transferred to the floor on telemetry. early morning patient was noted to have aflutter with rvr and cardiology was consulted. he received lopressor and a heparin drip was started for the ptt goal of 60-90. once therapeutic, a head ct was done which was stable. he remained stable with the plan for cardioversion/ablation on . he underwent this procedure and was cleared without issue. he was maintained on heparin drip overnight and was cleared for d/c home by cardiology with daily coumadin dosing and follow up with his pcp. he will see us in the office in 4 weeks with ct. he agrees with this plan medications on admission: none discharge medications: 1. warfarin 5 mg tablet sig: one (1) tablet po 5 pm: you are being prescribed 5mg tablets / your pcp change this dosing schedule . disp:*40 tablet(s)* refills:*2* 2. amiodarone 400 mg tablet sig: one (1) tablet po once a day: stay on this dose until seen by dr . he change your dosing. disp:*30 tablet(s)* refills:*2* 3. metoprolol tartrate 25 mg tablet sig: one (1) tablet po twice a day. disp:*60 tablet(s)* refills:*2* 4. docusate sodium 100
