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: headache major surgical or invasive procedure: : evd placement history of present illness: 45f known only for htn (treated) found to have very severe h/a and vomitting on . ct head at osh shows sah and patient is transferred to for further eval. past medical history: htn social history: non-contributory family history: non-contributory physical exam: on admission: 127/77 55 15 100% sleepy but arousable; spanish speaking only; follows simple commands w all 4 ext. talks very minimally; able to tell her name but not location or time. perla, eomi; face symetric; tongue midline; moves all 4 ext symetrically and with full strength; no pronator drift; neck tenderness; on discharge: non focal pertinent results: labs on admission: 06:42pm blood wbc-20.7* rbc-4.71 hgb-10.6* hct-34.8* mcv-74* mch-22.5* mchc-30.5* rdw-16.8* plt ct-476* 06:42pm blood neuts-91.3* lymphs-7.0*

01:56am blood phenyto-10.6 imaging: ct/a head : ct head: again seen is diffuse bilateral subarachnoid hemorrhage within the sylvian fissures, basilar cisterns, prepontine and ambient cisterns. again seen are small bilateral hyperdense collections layering within the occipital horns. there is persistent effacement of the cortical sulci. the ventricular system is unchanged in size and configuration. -white matter differentiation is preserved. there is no evidence of acute territorial infarction. again noted is a mucous retention cyst in the right maxillary sinus. there is mild mucosal thickening involving both maxillary sinuses and several bilateral ethmoid air cells. no evidence of fracture. cta head: the vertebral arteries are codominant and patent. there is a 2.5 mm outpouching of the v4 segment of the left vertebral artery which may involve the pica origin (image 188 series 2; image 26 series 300b,image 21 series 301b). there is possible infundibular dilatation or ectasia involving the basilar artery at the origins of the superior cerebellar arteries. the intracranial internal carotid, anterior, middle, and posterior cerebral arteries are patent without evidence of occlusion, high-grade stenosis, aneurysm, or arteriovenous malformation. no additional aneurysms are identified. cta neck: the origins of the great vessels at the level of the aortic arch are unremarkable. the paired vertebral arteries are patent in their entirety. again seen is the 2.5 mm outpouching involving the v4 segment of the left vertebral artery. the extracranial common, internal, and external carotid arteries are normal in course and caliber without evidence of high-grade stenosis or occlusion. there are dependent atelectatic changes, left greater than right. there are mild degenerative changes of the cervical spine, most pronounced at c5-6. impression: 1. 2.5 mm outpouching of the v4 segment of the left vertebral artery which may involve the pica origin. 2. stable extensive bilateral subarachnoid hemorrhage with mild dilatation of the lateral ventricles, unchanged since the prior examination. ct brain impression: 1. mild increase in ventricular size following drain clamping. 2. evolving sah and left pica aneurysm clip. 3. persistent left parietal hyperdensity likely represents a vascular malformation. mr can be ordered for further characterization. brief hospital course: patient began experiencing a sever headache and vomiting and presented to osh on and was found to have sah on ct with a basilar tip aneurysm. she was trasnferred to for further management. she was lethargic but arousable and following simple commands upon presentation. due to her ct results an evd was emergently placed by dr. . she was started on nimodopine for vasospasm prohylaxis and on the morning of she underwent cerebral angiogram which showed a left pica aneurysm which was subsequently coiled. after the angiogram she was transferred to the icu where she was placed on vasospasm watch. she remained stable in the icu and her exam slowly improved. on she was awake and oriented to her self, location, and date and strength was full but was slightly lethargic and a language barrier was present as she is spanish speaking only. on her exam remained stable and she was much more awake and interactive with the exam. her evd was raised to 25. on it was noted that evd was slightly pulled out on imaging thus resecured with staples. on the evd was clamped at 10am and began to experience icp recordings in the 20's, max was 38- evd was reopened. she had a second clamping trial and the evd was successfully removed on . in the afternoon, it was noted that csf was draining from the evd site in which staples and dermabond was used to close the incision more accurately. it was unsuccessful, csf continued to drain from the site and sutures were placed to create better closure of incision. patient was asked to cough and no csf was observed. patient was again evaluated by pt for stairs, and they determined over the weekend that she was not yet ready to be discharged to home where she has 3 flights of stairs to climb. they reevaluated the patient on monday, and found that she was safe for discharge - she agrees with the plan. her incision remains dry. medications on admission: none discharge medications: 1. aspirin 325
