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 drug allergy information on file attending: chief complaint: asked to consult on atraumatic iph, ? sah major surgical or invasive procedure: placement of extra-ventricular drain, diagnostic angiogram history of present illness: : 28m who was playing soccer this afternoon when he had a sudden onset ha and right sided weakness and collapsed. he was taken to osh where he was scanned and a significant iph was identified. he was intubated at the osh for increasing lethargy. past medical history: unknown social history: unknown family history:

eos-0.7 basos-0.3 ct head w/o contrast 8:21 pm ct head w/o contrast reason: interval change medical condition: 26 year old man with ruptured avm s/p angio reason for this examination: interval change contraindications for iv contrast: none. clinical history: 26-year-old male with ruptured avm status post angio. evaluate for interval change. comparison: at 15:30. non-contrast head ct: large intraparenchymal hemorrhage in the left occipitoparietal lobe measures 5.0 x 2.0 cm and dissects into the left lateral ventricle. blood is seen within both lateral, third and fourth ventricles. compared to the prior exam, there is probably no significant change in the size of large intraparenchymal hemorrhage, allowing for different orientation of axial images. since the last exam, a ventricular shunt has been placed terminating within the right lateral ventricle via a right frontal approach. although direct comparison is difficult from prior exam given difference in orientation of the axial images, there is probably slight decrease in the degree of ventricular dilatation. high-attenuation material is seen within the sulci, particularly along the left cerebral hemisphere, which may represent subarachnoid blood, although delayed enhancement from recent contrast study is possible. there is no shift of normally midline structures. the -white matter differentiation is intact. the basal cistern, in particular the suprasellar is effaced. fluid is noted within the right maxillary sinus. the remainder of the visualized paranasal sinuses and mastoid air cells remain normally aerated. a right frontal scalp hematoma is present with tiny locules of air within the subcutaneous tissues around the ventricular shunt. impression: 1. large intraparenchymal hemorrhage centered within the left occipitoparietal lobe with blood dissecting into the lateral, third and fourth ventricles. compared to prior exam, there is no significant change in the size of the intraparenchymal hematoma, although there may be slightly increased amount of blood within the ventricle. 2. status post placement of a right frontal ventricular shunt terminating within the right lateral ventricle with slightly decreased size of the ventricles. cta head w&w/o c & recons 3:16 pm cta head w&w/o c & recons reason: eval aneurysm medical condition: 26 year old man with ich/sah reason for this examination: eval aneurysm contraindications for iv contrast: none. ct angiography of the head history: ct angiography using a bolus enhancement technique. preliminary report: provided by dr. . he indicated "large left occipital temporal intraparenchymal hematoma with surrounding edema. a large amount of intraparenchymal hemorrhage is present in the ventricular system, which demonstrates some degree of hydrocephalus involving the temporal horns. the source of bleed is a large dural avm in the left occipital region with arterial source appearing to be the left posterior cerebral artery and a large draining vein to the superior sagittal sinus, possibly a vein of trolard." findings: the large left posterior temporal occipital hemorrhage, with extensive intraventricular hemorrhage is seen. there is moderate right and milder left-sided temporal enlargement. there is no shift of normally midline structures. the ct angiogram confirms the presence of a large vascular malformation, which appears to be primarily of pial, rather than dural origin. the major vascular feeder appears to be the left posterior cerebral artery, although there may well be contribution from distal branches of the left anterior cerebral artery arising from the pericallosal division. the nidus of the vascular malformation is situated along the superior aspect of the hemorrhage. there is some lobulation of this nidus. certainly, an intranidal aneurysm cannot be entirely excluded on the basis of this non-selective study. the major draining vein, as noted by dr. , appears to merge with the posterior aspect of the superior sagittal sinus. however, its very posterior location is not compatible with the designation of the vein of trolard. no other definite vascular abnormalities are demonstrated. conclusion: large pial-based arteriovenous malformation within the left parietal- occipital region. clearly, this malformation requires superselective angiography for complete mapping of its vascular supply, but especially for improved analysis of the nidus for the presence of potential intranidal aneurysms. ct head w/o contrast 10:20 am ct head w/o contrast reason: new hippus, ? worsening bleed/ icp medical condition: 26 year old man with large ich reason for this examination: new hippus, ? worsening bleed/ icp contraindications for iv contrast: none. history: known large left intraparenchymal hemorrhage with associated avm and worsening hiccups. evaluate for worsening bleed or signs of increased intracranial pressure. comparison is made to multiple prior cts dated . non-contrast head ct the overall size of the known left temporal-occipital intraparenchymal hemorrhage has displayed no interval change, with decreased blood noted within the ventricular system, especially anteriorly. the positioning and appearance of the right intraventricular drain is unchanged, as is the size of the lateral, third, and fourth ventricles from most recent exam. the amount of edema surrounding the intraparenchymal hemorrhage is stable, with maintenance of -white differentiation in remaining portions of the brain. no new regions of intraparenchymal hemorrhage are identified. no significant midline shift or signs of uncal herniation are noted. soft tissues and osseous structures are unremarkable. mild-to-moderate mucosal thickening involving the maxillary sinuses bilaterally with partially aerosolized secretions is again noted, with remaining paranasal sinuses and mastoid air cells appearing well aerated. impression: 1. no interval change in size of left temporal-occipital intraparenchymal hematoma. no ct findings to suggest elevated/worsening intracranial pressure. 2. interval decrease in amount of intraventricular hemorrhage with degree of dilatation involving the temporal horns appearing stable from most recent exam but improved from patient's original ct examination prior to drain. brief hospital course: the patient was admitted to the icu from the er to the neurosurgical service. an evd was placed for monitoring and prevention of hydrocephalus. dilantin was started for seizure prophylaxis and nimodipine was started for vasospasm prophylaxis. he was maintained on nafcillin for the drain. an angiogram was obtained which showed a large avm supplied by the l pca draining into ss sinus, also supplied by l aca as branches, no aneurysm noted. a post angio ct was stable. on hd 2 his neurological exam was improving. he was also seen by the neurology consult service. on hd#3 the patient pulled out his own et tube. his cvp was noted to range from with the evd open at 20cm above the tragus. arrangements were made for his transfer to under the care of dr. for further management of his large avm. medications on
