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: lisinopril attending: chief complaint: l mca aneurysm major surgical or invasive procedure: l craniotomy for aneurysm clipping cerebral angiogram history of present illness: as you will recall, he was seen in recently with a history of headaches and with one episode where he had severe right-sided headache after working out in the gym. as part of the workup, he had a ct of the brain, which showed a 4-mm aneurysm at the distal branch of the left middle cerebral artery. given his relatively young age, he is here for further treatment options. past medical history: tetralogy of fallot, cirrhosis, hepatitis, htn past surgical history is significant for sinus surgery, tonsillectomy and repair of tetralogy of fallot. social history: married, no smoke family history: nc physical exam: on examination today, his blood pressure was 148/90, heart rate was 70 per minute. chest showed good air entry bilaterally. heart: s1, s2 heard. regular rate and rhythm. soft systolic murmur. neurologic examination: awake, alert and oriented x 3. memory, recent and remote is good. pupils are equal and reactive to light. extraocular movements are intact. facial sensation is intact bilaterally. facial motor function is symmetric. tongue is in the midline. motor strength is in all four extremities. gait and coordination was normal. discharge exam: patient is aox3, perrl, eom intact, incision is c/d/i, no drift, motor is bilaterally, sensory is intact, face symmetric. gait is steady. pertinent results: mr head w/ contrast findings: the cerebral sulci, ventricles and extra-axial csf-containing spaces have normal size and configuration. there is no shift of the midline structures. there is no evidence of mass, mass effect or abnormal enhancement. redemonstrated is a 5-mm aneurysm involving the left mca m3/m4 branch. the visualized paranasal sinuses and mastoid air cells are clear. the orbits are unremarkable. impression: mri obtained for the purpose of surgical mapping with redemonstration of left m3/m4 segment middle cerebral artery aneurysm radiology report carot/cereb study date of 11:28 am satisfactory clipping of the distal left mca aneurysm with no definite residual aneurysm or major vessel clipping. ct head w/o contrast study date of 5:23 pm findings: the patient is status post a left frontal craniectomy. subdural hemorrhage at the surgical site is minimal. aneurysm clips are seen in the left frontoparietal region. no major vascular territorial infarctions, edema, or shift of midline structures present. ventricles and sulci are normal size and configuration. -white differentiation is preserved. visualized paranasal sinuses and mastoid air cells are well aerated. impression: status post left craniectomy for aneurysm coiling. residual subdural hemorrhage. no new hemorrhage. chest (portable ap) study date of 5:33 pm there is an endotracheal tube whose distal tip is 4.6 cm above the carina, appropriately sited. heart size is upper limits of normal. there is no focal consolidation. there is atelectasis at the left lung base. there are no pneumothoraces. there are no signs for overt pulmonary edema. ct head w/o contrast study date of 8:27 am impression: status post left craniotomy for aneurysm coiling with minimal left adjacent subdural hemorrhage. no new acute intracranial hemorrhage. large soft tissue swelling overlying the surgical site unchanged from the prior examination. a small hypodense focus is noted in the right sublentiform region/basal ganglia- cyst/lacune; unchanged from prior cta study. consider mr if not ci, if there is continued concern for acute infarct. brief hospital course: this is a 35 year old male with left mca aneurysm who presented for elective craniotomy for clipping of aneurysm. he was taken to the or on . the patient was admitted to sicu intubated/sedated post procedure. a ct of head revealed appropriate post surgical changes. the patient was extubated over a cook catheter. the patients respiratory status was stable. on , possible seizure activity noted in right hand and right eyebrow. the patient was loaded with keppra and the standing keppra dosing was increased to 1gm . the patient complained of puritus following oxycodone. benadryl provided no relief. sarna lotion releaved pruritus. on , the jp drain was removed and two staples were placed for closure. the patient's pain was controlled with dilaudid and zofran. the patient experienced intractable nausea with st changes on telemetry. troponins sent and were negative for the first set of three whiche were all negative. a repeat ct head obtained showing no new evidence of hemorhage and expected post operative changes. the patient was oriented to person, place, and time, and was full strength. due to st changes, nausea, and continued headache patient was kept overnight in the icu. a physical therapy consult was placed and the patient's foley catheter was discontinued. 0n patient was transferred to floor in stable condition. he was noted to have a critical low k of 2.9. he was given 60 meq of potassium with good response. now dod, patient is afebrile, vss, and neurologically stable. patient's pain is well-controlled and the patient is tolerating a good oral diet. pt's incision is clean, dry and intact without evidence of infection. patient is ambulating without issues. he is set for discharge home in stable condition and will follow-up accordingly. medications on admission: losartan 100 mg daily discharge medications: 1. acetaminophen-caff-butalbital tab po q8h:prn headcahe do not exceed 2 grams tyenol in 24 hours rx *butalbital-acetaminophen-caff 50 mg-325 mg-40 mg three times a day disp #*80 tablet refills:*0 2. docusate sodium 100 mg po bid rx *colace 100 mg twice a day disp #*60 capsule refills:*0 3. levetiracetam 1000 mg po bid rx *keppra 1,000 mg twice a day disp #*60 tablet refills:*0 4. losartan potassium 100 mg po daily 5. oxycodone (immediate release) 5-10 mg po q4h:prn pain rx *oxycodone 5 mg every four (4) hours disp #*40 tablet refills:*0 6. sarna lotion 1 appl tp daily:prn pruritus discharge disposition: home discharge diagnosis: l mca aneurysm headache hypokalemia discharge condition: mental status: clear and coherent. level of consciousness: alert and interactive. activity status: ambulatory - independent. discharge instructions: ?????? have a friend/family member check your incision daily for signs of infection. ?????? take your pain medicine as prescribed. ?????? exercise should be limited to walking;
