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: mr. is a 33-year-old man with a history of resected left pilocytic astrocytoma at age 22 months and status post whole brain xrt. he developed seizures in childhood. his seizure phenotype has been predominantly complex partial seizure with secondary generalization. his most recent secondarily generalized seizure prior to the current admission was beginning of . approximately two weeks prior to admission, he had another generalized seizure with a prolonged postictal phase, and was taken to , where a head ct scan was normal and he was discharged home from the emergency room. at home, however, he continued to be lethargic and was eventually brought to emergency department on for further evaluation. subsequent mri shortly after admission to , showed blood products in both frontal and occipital lobes and some associated t2 hyperintensity suggesting diffuse axonal injury. he was admitted to the neuro-icu, where on subsequent days, he showed gradual recovery with progressively decreasing lethargy. past medical history: 1. complex partial seizures as above. 2. nephrolithiasis (presumed secondary to topamax therapy). medications on admission: 1. topamax 350 mg . 2. depakote 500 mg tid. 3. trileptal 300 mg . allergies: no known drug allergies. family history: no epilepsy. social history: mr. is functioning in the community. he was assisting in the library, and now works for gateway. he lives with a roommate in an assisted-living facility. he does not smoke. he does not consume alcohol. he does not do drugs. examination on admission: mr. was drowsy on admission. he responded to questions with only single words. in-fact he only uttered yes, no, right, or . he was oriented to name only. otherwise, his pupils are equal, round, and reactive with impaired smooth pursuit and nystagmus and downward gaze. his face on admission was even. his tongue and palate were midline. his tone was normal. he had no tremor. he had mild left pronator drift, but otherwise was full power. his left plantar reflex was upgoing. he was generally lethargy and uncooperative, therefore gait and coordination were not tested on admission. in subsequent days, mr. showed gradual improvement. on day of discharge, he is able to stand and walk independently. he has apparent full power throughout. he is oriented to person and hospital, although not oriented to time. his mental status examination is notable for shortened attention with a digit span of . there are no new motor findings. in short, the most notable change at time of discharge is a change in mental status from baseline. mr. is being discharged to a rehabilitation, where he can receive physical therapy, but more importantly cognitive rehabilitation therapy for traumatic brain injury and presumed diffuse axonal injury. discharge medications: 1. topamax 350 mg po bid. 2. depakote 500 mg po tid. 3. tylenol 325-650 mg po q4-6h as needed. 4. zantac 150 mg po bid. 5. trileptal 600 mg po bid. addendum: in the course of mr. admission, urine culture showed an e. coli urinary tract infection. mr. was therefore started on bactrim po. he is to continue this medication for 10 days total. a repeat urine culture was drawn before discharge. results are pending at this time. follow-up instructions: mr. is to follow with epilepsy at . appointment to be made before discharge. this is a partial discharge summary to be addended on actual day of discharge. , m.d. dictated by: medquist36 procedure: electroencephalogram diagnoses: urinary tract infection, site not specified accidents occurring in residential institution personal history of irradiation, presenting hazards to health personal history of malignant neoplasm of brain other and unspecified intracranial hemorrhage following injury without mention of open intracranial wound, with brief [less than one hour] loss of consciousness intracranial injury of other and unspecified nature without mention of open intracranial wound, with brief [less than one hour] loss of consciousness fall resulting in striking against other object localization-related (focal) (partial) epilepsy and epileptic syndromes with complex partial seizures, with intractable epilepsy 

Answer: The patient is high likely exposed to
