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: pt is a 73 yo male with pmh sig for htn and prostate ca s/p prostactectomy in who presents w/complaints of r arm weakness(stable) x ~2 weeks. also c/o l frontal ha x3 days that is intermittent and dull in quality. major surgical or invasive procedure: left frontal craniotomy history of present illness: he tells me he has been in for the past several weeks and just arrived back in the us yesterday. approximately 2 weeks ago, the patient was driving his car at a low speed and lost consciousness. he hit a nearby tree but did not sustain any significant injuries. he went to the hospital and the doctors apparently told he likely had a stroke. then 3 days later, he woke-up with weakness in the right arm and this weakness has been there (and stable) every since that point. for the past 3 days, he also complains of a headache, located over the left frontal area, and dull in quality. it is intermittant in duration coming on a couple times a day and lasting 3 hours. it is relieved with tylenol. he decided to present to the ed on and was admitted past medical history: hypertension h/o prostate cancer s/p prostatectomy in social history: social history: -lives with son -originally from 20 pack-year smoking history -denies any recent alcohol use family history: family history: -denies any family history of seizures or strokes physical exam: vitals: 97.8 168/88 72 18 100 on room air general: well nourished older man in no acute distress neck: supple lungs: coarse breath sounds at the bases cv: regular rate and rhythm abdomen: non-tender, non-distended, bowel sounds present ext: warm, no edema neurologic examination: mental status: awake and alert, cooperative with exam, normal affect oriented to person, place, month and president attention: can say months of year backward and forward language: fluent, no dysarthria, no paraphasic errors, naming intact (although exam limited by language barrier) fund of knowledge normal registration: items, recall items at 3 minutes cranial nerves: visual fields are full to confrontation. pupils equally round and reactive to light, 3 to 2 mm bilaterally. extraocular movements intact, no nystagmus. facial sensation intact b/l;

while this appearance would also be consistent with calcification, no calcification was seen on the head ct of the same day. there is also a rim of increased susceptibility around the right cerebellar mass, also consistent with blood products. these masses most likely represent metastases. there are multiple small foci of t2 signal hyperintensity in the periventricular and subcortical white matter bilaterally, without any associated mass effect or enhancement, consistent with chronic microvascular disease. no signal abnormalities are present in the cortex overlying the left posterior frontal, parietal, and the occipital vasogenic edema. in retrospect, the cortical thickening noted on the preceding ct scan was likely related to volume averaging artifact. circle of mra: technique: three dimensional time of flight imaging was performed. multiplanar maximal intensity projections were obtained. findings: flow is visualized in the major tributaries of the circle of . there are no areas of vascular stenosis or occlusion. impression: 1. left parietal and right cerebellar necrotic, hemorrhagic masses which are consistent with metastases. 2. severe edema and moderate-to-severe shift of midline structures associated with the left parietal mass. mild edema associated with the right cerebellar mass. 3. no evidence of acute ischemia. 4. normal mra of the circle of . ------ mri : findings: comparison is made to the prior examination of . since the prior examination, the patient has had surgery on the left parietal lesion. there is no residual enhancing tissue within this area. there is a small postoperative fluid collection in this area as well as a small subdural with no significant mass effect. there is blooming artifact on gradient echo images, likely related to a small amount of air. the amount of adjacent edema within the frontal and parietal lobes is unchanged from the prior examination with some mass effect upon the midline structures as well as the posterior and anterior horns of the left lateral ventricle. these changes are not different than on the prior. there is a small right cerebellar enhancing lesion with a mild amount of surrounding edema as noted on the prior examination consistent with metastatic disease. an area of low t2 signal within this lesion could be consistent with some necrosis. multiple t2-signal abnormalities are seen also within the basal ganglia bilaterally and periventricular white matter, most consistent with chronic microvascular ischemia. these lesions do not enhance. diffusion-weighted imaging demonstrates no evidence of acute infarct. minimal artifact is seen surrounding the postop cavity. impression: status post surgery on the left parietal lesion with no significant residual enhancing tissue. stable right cerebellar metastasis. no significant change in the left parietal or right cerebellar vasogenic edema. ------ pathology from lesion: left high parietal lesion (including intraoperative smear): metastatic adenocarcinoma with cribriform histology and extensive necrosis. note: possible primary sites include lung, salivary gland, and gastrointestinal tract. to further characterize this lesion, additional stains are pending; their results will be issued in an addendum. brief hospital course: mr was admitted to the neurology service and underwent a mri which showed a left occipital heterogenous enhancement and right cerebellar lesion. cxr showed a mass in rml brain mass was thought to metastatic. he was given a decadron 10mg iv load dose and started on keppra prophylactically. to a goal dose of 1500mg he was brought to the or on and underwent a left sided craniotomy for tumor removal. intraoperatively he was noted to have an episode of bradycardia with rate 30-40s which did not effect his bp, he also had a similar episode in the recovery room which required administration of 0.5mg of atropine. postoperatively he was awake, alert, following commands and appropriate. he had a slight right sided drift and slight right sided upper extremity weakness. he spent the night in the pacu where he remained neurologically and hemodynamically stable. he had post-operative mri which showed no complications and was transferred to the surgical floor. he was evaluated by ot/pt he was found to be ataxic and have a partial right sided neglect and would benefit from rehab. radiation-oncology saw the patient and will follow up with him as an outpatient for planning session , with treatment starting soon afterwards. he also has an appointment scheduled in the brain tumor clinic in 2 weeks to discuss his full treatment course. his steroids should be weaned to 2mg over the next few weeks. he should be maintained on protonix while on these steroids. he was also sent to rehab on insulin sliding scale given effect of decadron of blood glucoses. on discharge, his rue weakness had improved and he was neurologically and medically stable. medications on admission: none discharge medications: 1. acetaminophen 325 mg tablet sig: 1-2 tablets po q4-6h (every 4 to 6 hours) as needed. 2. heparin sodium 5,000 unit/0.5 ml syringe sig: one (1) injection injection three times a day. 3. levetiracetam 500 mg tablet sig: three (3) tablet po bid (2 times a day). 4. dexamethasone 1 mg tablet sig: three (3) tablet po every eight (8) hours for 7 days: please take three tablets tid for 1 week, then 2 tablets tid for 1 week, then 2 tablets ongoing after that. . 5. pantoprazole sodium 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). 6. insulin regular human 100 unit/ml solution sig: per sliding scale per sliding scale injection asdir (as directed): please see enclosed sliding scale. discharge disposition: extended care facility: nursing facility discharge diagnosis: metastatic lung ca discharge condition: neurologically stable discharge instructions: keep incision clean and dry watch for redness, drainage, swelling or if you develop a fever greater than 101 call dr office do not get incision wet until sutures removed followup instructions: follow up in brain tumor clinic at 1:00, please come to the radiation oncology department (basement of ) on at 2 pm to discuss radiation treatments to your brain. procedure: other operations on extraocular muscles and tendons other excision or destruction of lesion or tissue of brain diagnoses: unspecified essential hypertension personal history of malignant neoplasm of prostate other convulsions other specified cardiac dysrhythmias secondary malignant neoplasm of brain and spinal cord malignant neoplasm of middle lobe, bronchus or lung
