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: fever major surgical or invasive procedure: none history of present illness: 53 yo male with pmh of htn, who presented with fever. he notes that he had back pain and l flank pain on sunday, sharp in nature and worse with exhalalation. he was seen at hospital and diagnosed with kidney stones when he had +rbc in urine. he was given percocet and sent home. since then he has had fevers to 37.8. the pain in his back was somewhat improved. he notes he does not take his antihypertensives regularly. he denies cp, sob, dysuria, changes in vision, headache. he presented to the ed and was found to have elevated bp to 210/100. cta was performed that showed extensive intramural thrombus of aorta. he was given lopressor iv and po initially and then started on esmolol and nipride drips. his bp decreased to 123/47vascular and ct eval'd pt in ed. type b dissection with no end organ malperfusion, rec bp control. past medical history: hypertension social history: lives with wife, one son. former social smoker (/wk), occasional etoh, no drugs. family history: mother with htn

ventricular hypertrophy, minor st-t wave abnormalities. since previous tracing of , no significant change . ctu: 1. findings consistent with an intramural hematoma of the aorta extending from the upper most image acquired on this study above the diaphragmatic hiatus through to the level of the aortic bifurcation, possibly involving the right common iliac artery. the celiac artery, sma, left renal artery, and appear patent. the right renal artery also appears patent although evaluation is considered suboptimal. 2. multiple left-sided renal cysts and multiple hypodense lesions too small to characterize in the kidneys bilaterally that may represent cysts. no renal stones identified. no hydronephrosis. . cta: aortic intramural hematoma that appears to extend proximally from the level of the take off of the left subclavian artery, and distally through to the level of the bifurcation of the aorta, also apparently involving the proximal right common iliac artery. the celiac artery, sma, renal arteries, and all appear patent. . cta: compared to the exam of , no significant change in the appearance of the aortic intramural hematoma. no evidence of new retroperitoneal hemorrhage or fluid collections. . mri l-spine: 1. no evidence of epidural abscess. 2. diffusely abnormal bone marrow signal, which appears nonspecific but may be seen in diffuse bone marrow infiltration or chronic illness. clinical correlation suggested. 3. distended bladder. clinical correlation suggested. . cxr: no radiographic evidence of pneumonia . tte: 1. the left atrium is mildly dilated. 2. the left ventricular cavity is mildly dilated. regional left ventricular wall motion is normal. overall left ventricular systolic function is normal (lvef>55%). 3. the ascending aorta is moderately dilated. the aortic arch is mildly dilated. 4. mild (1+) aortic regurgitation is seen. 5. no evidence of endocarditis seen. . mri c-spine () 1. no evidence of an epidural abscess. 2. cervical spondylosis with mild central stenosis and severe narrowing of neural foramina at multiple levels. . mri t-spine () no evidence of an epidural abscess brief hospital course: 1) aortic dissection: intramural aortic hematoma seen on ct scan in ed. vascular surgery consulted who felt it was consistent with a type b aortic dissection. he was admitted to the ccu for aggressive bp control. he was on a nipride and esmolol drip and eventually transitioned to po agents. he had a repeat ct scan which revealed a stable appearance of the aorta. he was scheduled a follow up appoinmtent with vascular surgery after discharge. he should also have a follow up ct scan after discharge which should be arranged by his primary care doctor. . 2) hypertension: his blood pressure was controlled with high dose lisinopril, labetalol, norvasc. labetalol was continually titrated up for difficult to control blood pressure. eventually, clonidine was also added for better control, which was achieved prior to discharge. at the time of discharge, he was given a clonidine patch and transitioned off po clonidine with a 3 day taper. he was instructed to have his blood pressure checked (by vna and on his own), and call his doctor if he noticed that it was >140/90 or <90/50. he was also told to call his provider or go to the er if he experienced chest pain, difficulty breathing, dizziness, or blurry vision. . 3) fever: patient had a low grade temperature at admission and it continued throughout his hospital course. he had an extensive work-up including mri spine (negative for epidural abscess), tte (negative for vegetation), blood cultures (negative), urine cultures (negative), ppd (negative), hepatitis panel, hiv test (negative). ultimately, the infectious disease service felt that his fevers were due to his aortic intramural hematoma. eventually, he became afebrile while off all antibiotics for several days. . 4) anemia: patient's hct was in low thirties. work-up revealed low iron, normal tibc, and high ferritin, as well as a borderline low b12 level. the mri of the l-spine commented on a diffusely abnormal signal pattern from the bone marrow. heme/onc was consulted who preformed a bone marrow biopsy. it was consistent with findings of anemia of chronic disease or inflammation. medications on admission: lopressor 50 mg (does not take regularly) combination of ?hctz and acei (does not take regularly) asa discharge disposition: home with service facility: family & services discharge diagnosis: 1) fever 2) aortic dissection discharge condition: stable discharge instructions: please call your doctor or return to the er if you experience fever, chills, chest pain, difficulty breathing, dizziness/lightheadedness, blurry vision, or difficulty walking. you should check your blood pressure daily and call dr. if it is higher than 140/90 or lower than 90/50. please take your medications as prescribed and follow up as scheduled below. followup instructions: 1) please follow up with your primary care physician (dr. ) on at 12:45. . 2) please follow up with dr. in vascular surgery on at 3:00 pm. medical office building, . procedure: biopsy of bone marrow diagnoses: acute kidney failure, unspecified hypertensive chronic kidney disease, unspecified, with chronic kidney disease stage v or end stage renal disease iron deficiency anemia, unspecified dissection of aorta, abdominal
