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: demerol attending: chief complaint: right knee pain major surgical or invasive procedure: right total knee arthroplasty history of present illness: 51 yo woman complaining of right knee pain. patient had traumatic mcl tear to right knee 21 years ago. patient has had increasing pain in right knee since injury. pain is now affecting daily activities. past medical history: osteoarthritis hypertension social history: etoh-occasional tob-denies ivda-denies physical exam: gen-a&ox,nad vs-hr-51 spo2-100%ra cv-rrr s1/s2 lungs-cta abd-soft nt/nd ext-no club/cyanosis/edema, decreased rom right knee secondary to pain. pertinent results: ct angiogram: tiny filling defect in a segmental right upper lobe pulmonary artery is most likely representative of streak artifact. no evidence of occlusive thrombus. eeg: this is a mildly abnormal portable eeg due to the presence of delta with mixed theta frequency slowing seen over the left temporal and parietal regions. this finding suggests subcortical dysfunction in these areas and is a relatively non-specific finding with regard to an evaluation for seizures. no epileptiform abnormalities were seen. brain mri: heterogenous left temporal lobe mass with calcification and/or blood products without distinct enhancement. no significant surrounding edema. the differential diagnosis includes cavernous malformation however given the irregular distribution of the blood products, the appearance is not typical. ct r knee: status post right total knee replacement with complex postoperative flusion. otherwise unremarkable examination. 12:34pm glucose-94 urea n-13 creat-0.8 sodium-145 potassium-3.7 chloride-106 total co2-30* anion gap-13 12:34pm calcium-8.9 phosphate-4.0 magnesium-1.9 12:34pm wbc-4.6 rbc-3.38* hgb-11.6* hct-31.7* mcv-94 mch-34.3* mchc-36.5* rdw-12.7 12:34pm plt count-201 01:53am blood glucose-178* urean-9 creat-0.8 na-123* k-2.9* cl-86* hco3-22 angap-18 06:05am blood glucose-140* urean-9 creat-0.6 na-120* k-2.9* cl-84* hco3-30* angap-9 11:22am blood urean-8 creat-0.6 na-127* k-3.0* cl-91* hco3-28 angap-11 03:45pm blood urean-8 creat-0.6 na-136 k-3.7 cl-99 hco3-26 angap-15 07:58pm blood na-138 k-3.7 11:51pm blood creat-0.6 na-140 k-4.0 cl-105 hco3-26 angap-13 01:53am blood wbc-20.9*# rbc-2.38* hgb-8.1* hct-22.0* mcv-93 mch-34.2* mchc-36.9* rdw-12.5 plt ct-195 06:05am blood wbc-18.7* rbc-2.30* hgb-8.0* hct-20.8* mcv-90 mch-34.5* mchc-37.4* rdw-12.5 plt ct-193 07:15am blood wbc-8.3 rbc-3.09* hgb-9.5* hct-27.6* mcv-89 mch-30.7 mchc-34.4 rdw-14.7 plt ct-290 brief hospital course: 1. right total knee arthroplasty - patient had been followed by dr. in clinic prior to her admission for an elective total knee arthroplasty. consent was obtained in clinic, medical clearance was also obtained prior to surgery. patient was admitted on for an elective right total knee arthroplasty. surgery was without complication, please see op-note . on post-op check patient was doing well. patient was afebrile/vital signs stable. dressing had moderate amount of drainage, dressing was reinforced and ice applied to incision. pt developed a hematoma around the area of the joint but there was no evidence of local infection, through to the day of discharge. she was sent home with percocet for pain relief, and vna was arranged to help with dressing changes and physical therapy. she was given iv ancef while in the hospital, and sent out on a 5-day course of keflex to prevent wound infection. she will also remain on lovenox for 4 weeks after discharge. she will follow up with dr. in clinic. 2. postoperative seizure - pt was stable immediately post op until 2:30am then she was noted to have generalized tonic-clonic seizures witnessed by rn, followed by brief periof of post ictal confusion. at the time, the eyes rolled back into head, arms extended and shaking and mouth twitching. the episode lasted minutes, no tongue biting or incontinence. pt became tachycardic to 114 during the seizure but did not desat. following seizure event, the patient had a brief period where she was "speaking non-sense" which subsequently resolved. pt was transferred to the . sodium dropped as low as 120 (down from 145 on ), hct 22 (from 31.7 on ), k was 2.9, and inr was 1.5. ct angio showed no pe. head ct showed a small lesion with calcifications in left inferior temporal lobe. of note, pt has been receiving continuous d5 1/2ns, poor po intake except for water and juice with significant pain in the postoperative period. pt did not have any recurrent seizures, and her hyponatremia corrected overnight with hypertonic saline initially, and then ns. it is thought that pain and postoperative hypotonic fluids caused her hyponatremia. however, due to the presence of the l temporal lobe lesion, neurology consult was called. an eeg was performed to evaluate for the likelihood that this mass was the etiology of the seizure. there was some slowing over the l temporal and parietal regions, but this was thought to be nonspecific and not necessarily consistent with epileptiform abnormalities. pt transferred to the floor with a stable sodium. 3. left temporal lobe lesion - after the ct scan showed this left temporal lobe mass, an mri was done to further evaluate the lesion. this showed a heterogenous left temporal lobe mass with calcification and/or blood products without distinct enhancement. no significant surrounding edema. the differential diagnosis includes cavernous malformation however given the irregular distribution of the blood products, the appearance is not typical. per neurology, this was likely a lesion that was fairly stable and not extremely likely to bleed, and with careful consideration, it was decided that the benefits of anticoagulation would outweigh the risk of intracerebral bleeding, given the appearance of this lesion on imaging studies. an eeg was performed, which did not particularly point to the lesion as the etiology of seizures. an lp was performed, mainly for cytologic analysis. pt will follow up with dr. in a few weeks, where she will receive the results of the lp. the mri reviewed by neurology and neuroradiology, and it was recommended that pt also be followed up in neurosurgery clinic, as there were some atypical features of this likely cavernoma, and surgical intervention may be indicated if there are multiple feeding vessels, which would increase her lifetime risk of hemorrhage. 4. anemia - most likely due to bleeding into leg. pt was given lovenox after recent surgery and developed a significant hematoma with a tense thigh, but did not develop compartment syndrome. ct scan showed edema with small hematoma (<100c), which did not explain a large hct drop. pt was given 2 units prbc, 1 unit ffp, and hematocrit held steady. 5. fevers - pt developed low grade temps the day prior to discharge. as pt was also tachycardic, she underwent cxr, which was negative for pneumonia, blood cultures, which are no growth to date, a urine culture, which was negative, and a ct angiogram to look for a pe. this, too, was negative. it is likely that her fevers are from postoperative atelectasis, or perhaps associated with the large hematoma at the site of her surgery. pt was clinically stable and feeling well, and was therefore discharged the following day. of note, the site of her incision was not consistent with any local infectious process. 6. hypertension - pt's hctz and lisionpril were initially held when pt developed hypokalemia. they were restarted 2 days prior to discharge, with good control of her blood pressure. medications on admission: lisionpril 20 hctz 25 protonix 40 naproxen mvi darvocet discharge medications: 1. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 2. lovenox 40 mg/0.4ml syringe sig: forty (40) mg subcutaneous once a day for 4 weeks. disp:*qs * refills:*0* 3. oxycodone hcl 5 mg tablet sig: 1-2 tablets po every three hours as needed for pain. disp:*60 tablet(s)* refills:*1* 4. keflex 500 mg tablet sig: one (1) tablet po every eight (8) hours for 5 days. disp:*15 tablet(s)* refills:*0* 5. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day): while taking percocet. disp:*60 capsule(s)* refills:*0* 6. hydrochlorothiazide 25 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 7. lisinopril 20 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 8. acetaminophen 500 mg tablet sig: two (2) tablet po q6h (every 6 hours): until pain resolves. disp:*240 tablet(s)* refills:*2* discharge disposition: home with service facility: homecare discharge diagnosis: right knee osteoarthritis hyponatremia hypokalemia discharge condition: stable discharge instructions: please cont with weight bearing as tolerated right leg. lovenox 40mg once a day x4weeks for anti-coagulation. oral pain medication as needed. please cont with physical therapy. please keep incision clean/dry. please call/return if any fevers/increased discharge from incision or trouble breating. followup instructions: provider: , md where: orthopedics phone: date/time: 2:40 provider: , md where: neurology -
