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: discharge condition: good. hospital course: patient is a 57-year-old female with syndrome who was diagnose with a left adrenal tumor noted to be a cortisol producing tumor. she also has a past medical history significant for an aortic valve replacement with a st. jude valve as well as a pulmonary arteriovenous malformation, which had recently been embolized in preparation for surgery. she presented 2 days prior to surgery in order to undergo heparinization for the aortic valve while she was off coumadin. she was taken to the operating room on monday and underwent attempted laparoscopic left adrenalectomy. the procedure needed to be converted to open due to difficult in visualization. the spleen was also removed at the time, because an injury to the spleen was noted and the patient's need for anticoagulation postop, it was felt that leaving an injured spleen in place was not prudent. postoperatively, the patient was placed on high dosed steroid therapy. her hospital course was complicated by steroid psychosis, which was resolved once steroid therapy was withdrawn. low dose steroids were replaced. her pulmonary status also remained an issue for a 1 week postoperatively as the patient was cpap dependent and oxygen dependent at home. this required aggressive diuresis and bipap therapy during the hospital. due to the aggressive diuresis, actually the patient did have an onset of acute renal insufficiency. this was corrected with replacement of iv fluid therapy. regarding her anticoagulation, the patient was begun on heparin drip and was noted to have some bleeding, which was obvious from her drain left in place in the surgical bed. the heparin drip was stopped and the patient was just maintained on coumadin therapy. her inr levels were rather variable ranging from 1.2 to 5.8. currently on discharge she is 1.8. right now maintained on half her coumadin dose of 2 mg a day. her respiratory status has reverted back to normal. she is without cpap during the day and just uses cpap at night. her renal function is also back to normal with a normal bun and creatinine as were her baseline. she did have some diarrhea in the hospital due to the multiple antibiotics she had received. we had placed her critically on flagyl therapy. however, she does have 3 c diff toxin a is negative and a toxin b culture is pending. this is now postop day 14 and near her baseline status and will likely be discharged home. neurologically the patient is completely at baseline. there is no evidence of psychosis at this time. cardiovascularly she has remained stable. she is on all her home medications for anti hypertension including atenolol and amlodipine. pulmonary wise she has also reverted back to her baseline and there is no evidence of a pneumonia. she is without cpap during the day and uses the cpap at night. she has a marginal pulmonary status in general but refuses adamantly to go to a rehab location where more attention could be given to her lungs. gi, the patient is tolerating a cardiac regular diet. gu, patient's renal function has resolved back to normal. she is able to void without a foley catheter. infectious disease, the patient is maintained on a 14 day course of flagyl. her cultures have all been negative, however, clinically it seemed that she may have had c difficile, thus she will be sent home on 10 days of flagyl therapy. heme, patient's inr today is 1.8. she is maintained on half her coumadin dose of 2 mg and this dose should be titrated to an inr of 2.0 to 2.5 for her aortic valve. endocrine, the patient's sugars have been well controlled under 120. she has not required insulin for 2 days. her prednisone dose is currently 10 mg once a day given in the morning. fen. the patient's electrolytes have been relatively normal. she is not receiving any iv fluids. this patient will be discharged home with home vna services and home pt services. she refuses to go to a rehab location despite our every attempt. , procedure: venous catheterization, not elsewhere classified venous catheterization, not elsewhere classified venous catheterization, not elsewhere classified continuous invasive mechanical
