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: worst headache of life major surgical or invasive procedure: cerebral angiogram x 3 history of present illness: 65 year old male who was home doing paperwork when he had sudden onset of the worst headache of life with neck pain. his daughter was with him and called ems. pt remained neurologically intact throughout transfer. past medical history: htn, high cholesterol, open cholecystectomy social history: never smoked, one drink with dinner, works as accountant, lives with wife, one daughter family history: no h/o aneurysm physical exam: initial exam t:96.5 bp: 136/74 hr:66 r 16 o2sats 96% gen: wd/wn, obvious discomfort keeping eyes closed, lying still, nad. heent: pupils:4->3 bilat eoms full neck: supple. extrem: warm and well-perfused. neuro: mental status: awake and alert, cooperative with exam, normal affect. 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, 4 to3 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 bilaterally. toes downgoing bilaterally pertinent results: cta head w&w/o c & recons 12:29 pm technique: axial images of the head were obtained without contrast. following this, using departmental protocol, ct angiography of the head was acquired. ct head: there is subarachnoid hemorrhage identified in the posterior fossa in the perimesencephalic region and around the foramen magnum. the subarachnoid hemorrhage also extends to the suprasellar cistern and also in the both medial portion of both sylvian fissures. there is subtle prominence of the temporal horns identified of both lateral ventricles. ct angiography of the head: the ct angiography of the head demonstrates no definite evidence of an aneurysm or arteriovenous malformation. somewhat tortuous distal cervical internal carotid arteries are identified. slight prominent appearance of the tip of the basilar artery on the sagittal reformatted images appears to be secondary to vascular structures projecting over the basilar tip. impression: 1. subarachnoid hemorrhage as described above. mild prominence of the temporal horns indicating early obstructive hydrocephalus. 2. no definite evidence of aneurysm on the ct angiography or evidence of abnormal vascular structures to indicate arteriovenous malformation. 3. given the presence of subarachnoid hemorrhage, negative ct angiography does not exclude an aneurysm and further evaluation with cerebral angiography is recommended. 4. findings were conveyed to the emergency room. carot/cereb 2:59 pm reason: 65 year old man with sah, r/o anerysm technique: the patient was brought to the interventional neuroradiology suite and placed on the biplane table in the supine position. both groins were prepped and draped in the usual sterile fashion. a preprocedure timeout was performed using two patient identifiers. access to the right common femoral artery was obtained with a micropuncture kit using the seldinger technique and 1% lidocaine mixed with sodium bicarbonate for local anesthesia. a 5 french vascular sheath was placed and connected to a saline infusion with a continuous drip. through the sheath, a 5 french 2 catheter was introduced and connected to a continuous saline infusion (mixed with heparin 1000 units with 1000 cc of saline). the following vessels were selectively catheterized and arteriograms were performed in the following locations: right vertebral artery, the brachiocephalic artery, the right common carotid artery, the right internal carotid artery and the left common carotid artery, and left internal carotid artery. after review of the films, the catheter and sheath were withdrawn. an angio-seal device was used to achieve hemostasis in the right groin. findings: the study is slightly limited due to patient motion. the right vertebral artery: there is filling of the basilar artery and its branches with reflux into the left vertebral artery. there is no aneurysm identified. there is no high-grade stenosis or occlusion of the vertebrobasilar system. brachiocephalic artery arteriogram: there is prompt flow and opacification of the right common carotid artery and the right subclavian artery as well as the right vertebral artery. no high-grade stenosis is seen at the origin of the right common carotid artery. right common carotid arteriogram: visualization of the distal common carotid artery demonstrates no high-grade stenosis or occlusion. there is prompt filling of the external and internal carotid arteries. the internal carotid artery fills well along its cervical, petrous, cavernous and supraclinoid segments. the right internal carotid artery bifurcates into the anterior and middle cerebral arteries. there is no high-grade stenosis or occlusion of the anterior and middle cerebral arteries on the right side. there is no aneurysm identified. no vascular malformations are seen. the origin of the right internal and external carotid arteries demonstrates no stenosis or occlusion. the left internal carotid artery fills well. the left internal carotid artery also fills well along its cervical, petrous, cavernous and supraclinoid segments. the visualized anterior circulation including the anterior and middle cerebral arteries shows no high-grade stenosis or occlusion. no evidence of aneurysms identified. the anterior communicating artery is visualized and appears normal. conclusion: cerebral angiogram of mr. demonstrates no aneurysm. vascular malformations identified to explain the patient's subarachnoid hemorrhage. a followup angiogram will be performed to further evaluate for possible aneurysm or vascular malformation. carot/cereb 8:05 am technique: informed consent was obtained from the patient after explaining the risks, indication, and alternative management. risks explained include stroke, loss of vision and speech, nerve deficits and bleeding. the patient was brought to the interventional neuroradiology theatre and placed on the biplane table in the supine position. the patient was intubated under general anesthesia. both the groins were prepped and draped in the usual sterile fashion. access to the right common femoral artery was obtained with single-wall needle. an 8 french vascular sheath was placed and connected to a saline infusion. through the sheath, a 5 french 2 catheter was placed and advanced into the left vertebral artery, left common carotid artery and the right common carotid arteries. following selective catheterization of each vessel, ap and lateral projections were obtained. after review of the films, the catheter and sheath were withdrawn and the puncture site sealed with an angioseal device. findings: left vertebral artery: injection of the left vertebral artery shows the basilar artery and its branches filling well with reflux into the right vertebral artery and both posterior inferior cerebellar arteries visualized. both posterior cerebral arteries are visualized and appear normal. there are no aneurysms, filling defects or stenosis of the vertebrobasilar system demonstrated. left common carotid arteriogram: the left external carotid artery fills well. the left internal carotid artery fills well along its cervical, petrous, cavernous and supraclinoid segments. the anterior circulation including the a1 and a2 segments of the anterior cerebral artery and m1 and m2 segments of the middle cerebral artery fills well and appears normal. the anterior communicating artery is visualized and appears normal. there is no evidence of any aneurysm, filling defect or stenosis right common carotid arteriogram: the right common carotid artery shows no significant stenosis. the right common carotid artery fills well and appears normal. the right internal carotid artery fills well along its cervical petrous, cavernous and supraclinoid segments. the a1 and a2 segments of the anterior cerebral artery and the m1 and m2 segments of the middle cerebral artery fills well and appears normal. there is no evidence of any aneurysm, filling defect or stenosis after the cerebral angiogram, the patient had a left-sided hemiparesis for which another cerebral angiogram was performed, the details of which will be dictated in a separate report. conclusion: mr. underwent a cerebral angiogram to assess for possible aneurysm. the cerebral angiogram could not conclusively demonstrate an aneurysm which could explain the patient's known subarachnoid hemorrhage. ct head w/o contrast 8:46 am prior studies: ct angiogram done on along with non-contrast ct head. technique: non-contrast ct of the head was performed. findings: there is a hypodense area, in the right occipital lobe, medially, which is new, and represents an acute infarct. there is also a small hypodense area, noted in the right insular cortex/external capsule region (series 2a, image 12), which is again new and can represent a small acute infarct. there is no significant change in the intraventricular (occipital ) and subarachnoid hemorrhage. the ventricles appear stable in size. there is no mass effect or shift of midline structures. the osseous and the soft tissue structures are unremarkable. impression: new acute infarcts in the right medial occipital lobe and right insular cortex/external capsule, in the pca and mca territories respectively. brief hospital course: mr. was admitted to the neurosurgical service on , for a subarachnoid hemorrhage. he was admitted to the icu for close monitoring and taken for a cerebral angiogram. he tolerated the procedure well and there was no evidence of any aneurysm or vascular malformation as the cause of the bleeding. he had further work up including mri/mra of the head and neck, cta head and ct perfusion which did not identify any etiology for the sah. he was taken back for a repeat angiogram on with no aneurysm or vascular malformation identified. after the procedure it was noted that he had left-sided hemiparesis for which a cerebral angiogram was immediately performed which demonstrated a right mca occlusion and he was subsequently given heparin and local arterial tpa with recannulization of the vessel. on a post procedure check his strength was bilaterally and he had a slight left facial droop and tongue was deviated to the left, but he was otherwise intact. on he complained of a bilateral central visual field loss. a ct was done which showed a new right occipital infarct. neuro-ophthalmology was consulted and will follow him as an outpatient for visual field assessment. he was transferred to the stepdown unit on and continued to do well. he worked with physical therapy and continued to be neurologically stable. he complained of some headache on which was not alleviated by tylenol and he was started on percocet which worked well. he was determined to be stable for discharge to rehab on . on discharge he is neurologically stable, 5/5 strength in bilateral extremities, continues to have a slight left facial droop, tongue deviated to the left and bilateral central scotomas. he will continue on keppra for seizure prophylaxis until follow up and will follow up with dr. in 1 month with a cta head. he will also follow up with ophthalmology as an outpatient.
