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: penicillins / percocet attending: chief complaint: sudden onset headache, visual changes major surgical or invasive procedure: l occipital craniotomy history of present illness: 68 year old male who was discharged earlier in the day after having a stent assisted coiling of a basilar artery aneurysm on . a few hours after going home he developed a sudden onset of headache behind his left eye as well as a right visual field cut. he went to hospital where a ct scan of the head was done which showed a left occipital hemorrhage. at the osh his exam was significant only for the field cut. he was transferred via to for further evaluation and management. inr was 0.99 at the outside facility. he also complains of nausea. past medical history: atrial fibrillation on

pt-12.5 ptt-25.6 inr(pt)-1.1 cta head and neck 1. new left occipital intra-axial hemorrhage and intraventricular extension identified. no hydrocephalus. effacement of sulci in left cerebral hemisphere and slight increased mass effect in the posterior fossa are noted. 2. ct angiography of the neck demonstrates no stenosis or occlusion. 3. ct angiography of the head demonstrates large coil artifact limiting evaluation near the basilar tip, but flow is identified within the stented portion of the distal basilar artery and in the proximal posterior cerebral arteries. 4. findings were discussed with dr. . ct head : overall stable size of left occipital hemorrhage. increased hemorrhage noted within the subdural space posteriorly and throughout the ventricular system. slight increase in rightward shift of midline structures, now measuring 8 mm. ct head : overall stable appearance of left occipital intraparenchymal hemorrhage with subdural and intraventricular blood as described above without significant interval change from the prior study from 6 a.m. continued rightward 9-mm midline shift and prominence of the temporal horns of the left lateral ventricle. ct head : overall, no significant change since and appearance of the brain. left occipital hematoma and left temporal dilatation are again noted. ct head : no significant interval change. overall stable appearance of the left occipital hemorrhage with subdural and ventricular extension. a small amount of subarachnoid hemorrhage along the right vertex. stable shift of midline structures, roughly 7 mm. findings were discussed with dr. at the time scan done 10 a.m. on . cta head : 1. status post left occipital hemorrhage evacuation with partial improvement in mass effect. 2. limited evaluation of the intracranial arteries at the level of the suprasellar cistern due to extensive artifacts. it is not possible to evaluate patency of the stented distal portion of the basilar artery on this study. ecg atrial fibrillation with rapid ventricular response. low limb lead voltage. early r wave progression. precordial t wave inversions. since the previous tracing of the rate is faster. t wave abnormalities are more prominent cxr findings: in comparison with study of , there again are low lung volumes. there is continued substantial enlargement of the cardiac silhouette. there is mild prominence of the central pulmonary vessels, possibly reflecting early pulmonary edema. no evidence of acute focal pneumonia. head ct : stable post-op appearance. brief hospital course: mr. was admitted to the neurosurgery service and transferred to the icu after evaluation in the emergency room. he was given platelets after the ich was visualized. a repeat head ct which was obtained on following his admission was unchanged. on , he began to grow increasingly agitated, and therefore, a sitter was ordered for his room. the remained of his neurological exam remained unchanged. his repeat head ct was stable. on , he was extrememly agitated in the afternoon, and d/c'd his own a-line and ivs. a stat head ct was obtained, which revealed again a stable ich without change. haldol was given for sedation, but his blood pressure began to rise. the decision was made to intubate the patient for airway and bp control. the patient spiked a fever to 101.4 overnoc, and subsequent unire/blood cx were sent. on , it was decided that the patient would benefit from evacuation of the ich. he was taken to the or for a craniotomy for evacuation. he required 3 units of platelets intra op. blood loss was 1000cc. mannitol was discontinued. post-op hct was low and he received 2 units. aspirin and plavix were on hold. he was extubated on . on he was changed from dilantin to keppra. he was on q 4hour neuro checks. on he was more verbal. on sq heparin and asa was started. transfer orders were written for the sdu and repeat head ct for . due to bed availability the patient remained in the icu, the repeat head ct on was stable and the patient was transferred to the floor on . physical therapy assessed the patient and acute rehab was recommended. on the patient was accepted to in and was discharged. medications on admission: asa 325mg, plavix 75mg, zocor 40mg , atenolol 25mg, digoxin 250mcg daily, finasteride 5mg, warfarin 10mg (tu, w, , ), warfarin 5mg (m, th, fr) discharge

disposition: extended care facility: - discharge diagnosis: left parietal/occipital intracranial hemorrhage with intraventricular extension. discharge condition: mental status: confused - sometimes. level of consciousness: alert and interactive. activity status: ambulatory - requires assistance or aid (walker or cane). discharge instructions: general instructions ?????? have a friend/family member check your incision daily for signs of infection. ?????? take your pain medicine as prescribed. ?????? exercise should be limited to walking; no lifting, straining, or excessive bending. ?????? you may wash your hair only after sutures and/or staples have been removed. if your wound closure uses dissolvable sutures, you must keep that area dry for 10 days. ?????? you may shower before this time using a shower cap to cover your head. ?????? increase your intake of fluids and fiber, as narcotic pain medicine can cause constipation. we generally recommend taking an over the counter stool softener, such as docusate (colace) while taking narcotic pain medication. ?????? unless directed by your doctor, do not take any anti-inflammatory medicines such as motrin, advil, and ibuprofen etc. ?????? you may continue asa 325mg daily as prescribed but coumadin will be addressed in two weeks at your follow-up appt. ?????? clearance to drive and return to work will be addressed at your post-operative office visit. ?????? make sure to continue to use your incentive spirometer while at home, unless you have been instructed not to. call your surgeon immediately if you experience any of
