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: history of present illness: the patient is a 57-year-old right-handed woman who was evaluated by a neurologist for vertigo. she indicates she was in her usual state of good health until approximately five days prior to her evaluation when she had complaints of the acute onset of vertigo, a sensation of being off balance, and vomiting. she also reports associated blurry vision with no headache, tinnitus, sensory symptoms, or speech difficulties. her daughter, however, who was present during the interview today indicates that her speech was somewhat slurred. she was taken to hospital where a head computed tomography showed "an abnormality." she had a magnetic resonance imaging/magnetic resonance angiography of the brain which showed evidence of a right posterior communicating artery aneurysm. she was referred to dr. for endovascular vs. surgical therapy. she was admitted on for a conventional angiogram and consideration for endovascular treatment. physical examination on presentation: she was a well-developed woman who appeared in mild discomfort. her blood pressure was 120/80, her pulse was 72, her respiratory rate was 12, and she was afebrile. she was alert, awake, and fully oriented. speech and language function were intact. judgment, memory, and calculations were intact. affect was appropriate. there was no apraxia, agnosia, or neglect. cranial nerve examination revealed visual acuity was normal. she had a slight anisocoria with the left pupil approximately 4 mm in diameter and the right 3 mm. both were equal, round, and reactive to light. there was no horner syndrome or ptosis. the visual fields were full. extraocular movements were full in all directions. facial movement was intact. there was decreased sensation to touch on the left side of the face. hearing was intact to rub. the palate elevated symmetrically. motor examination revealed normal tone and muscle strength throughout. cerebellar function was normal except for subtle clumsiness of the finger-to-nose on the left side. she also had slight difficulty drawing a figure eight with the left foot compared to the right. deep tendon reflexes were 2+ throughout. summary of hospital course: she was admitted for angiogram for coiling of the right posterior communicating artery aneurysm. there were no intraoperative complications. postoperatively, she was monitored in the intensive care unit for close neurologic observation. she was started on heparin. the patient was in the intensive care unit recovering from the coiling when she had the onset of unresponsiveness and bilateral pinpoint pupils. her blood pressure rose to greater than 180 for a few minutes and then she had slight twitching of her head. she was immediately intubated and sedated and brought to head computed tomography which showed no evidence of bleeding or stroke. she was loaded prophylactically with dilantin and started on decadron. her blood pressure was kept at less than 140. on , the patient was alert, awake, and oriented times three. she had some double vision in the left lateral gaze. she had negative drift. she had a slight hematoma of the right leg. her iliopsoas were . her pulses were intact. her decadron was decreased. she was continued on dilantin. she was out of bed to chair. on , there was no seizure activity. she was alert, awake, and oriented times three and moving all extremities with good strength. no drift. she continued to have a left lateral gaze minimal diplopia. she was stable, and she was transferred to the regular floor. on , she continued to be neurologically stable without any evidence of seizures. alert, awake, and oriented times three. moving all extremities. her speech was fluent. discharge disposition: she was discharged on in stable condition with followup with dr. in one week. medications on discharge: 1. percocet one to two tablets by mouth q.4h. as needed. 2. decadron 2 mg by mouth q.6h. (for three days). 3. famotidine 20 mg by mouth twice per day. 4. dilantin 100 mg by mouth three times per day. 5. aspirin 325 mg by mouth once per day. condition at discharge: stable at the time of discharge. , m.d. dictated by: medquist36 procedure: insertion of endotracheal tube non-invasive mechanical ventilation arteriography of cerebral arteries endovascular (total) embolization or occlusion of head and neck vessels diagnoses: other convulsions other nervous system complications anxiety state, unspecified cerebral aneurysm, nonruptured other specified surgical operations and procedures causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation diplopia 

Answer: The patient is high likely exposed to
