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: history of present illness: the patient is a 36-year-old gravida 2/para 2 who was sent to gyn triage following a telephone call reporting a headache to the office. the patient was sent to gyn triage after she reported that she had been seen the previous day by her primary care provider who had done an evaluation; including a blood pressure that had been 120/60, and because of the persistent headache the patient was sent to the gyn triage area to be evaluated. additionally, the attending anesthesiologist was by telephone by the primary obstetrician, and this headache was discussed while the patient was en route to gyn triage regarding the proper approach to evaluation. the attending anesthesiologist on labor and delivery that day indicated that it sounded as though it may be a postural or spinal anesthesia related headache, and so the plan was formulated that the patient would be evaluated in a gyn triage area for obstetrical as well as anesthesia related condition with the possibility of the placement of a blood patch. the patient arrived to gyn triage and was evaluated by the chief resident in gyn triage. the patient had had a repeat elective cesarean delivery on and had an uneventful antepartum as well as postpartum course. the patient reported that she had been taking percocet for incisional pain since returning from the hospital after her discharge from her delivery on but that she had gradually decreased the amount of percocet that she was using for her incisional pain, and coincident with the decrease in the amount of percocet that she was taking she noticed that her headache had progressively been getting worse. at the time of the initial interview in gyn triage the patient denied any visual changes or abdominal pain, and the patient described her headache on the scale of 10 as and stated that the main area where it hurt her was over her eyes. she had taken 1 motrin approximately 3 hours prior to her arrival at gyn triage. she denied any symptoms of neck stiffness, and she reported that she got some relief from the headache in a supine position. past obstetrical history: notable for a low transverse cesarean delivery previously in . this was done emergently for the indication of a nonreassuring fetal heart rate tracing leading to a subsequent planned repeat cesarean delivery on . past medical history: negative. past surgical history: notable for only for her previous history of cesarean delivery twice as well as wisdom teeth operation. medications: at the time of her initial evaluation included only motrin. allergies: the patient has no known drug allergies. physical examination: at the time of her evaluation in gyn triage included a temperature of 99.0, a heart rate of 54, a respiratory rate of 16, and blood pressures as follows. blood pressure at 12:15 p.m. was 141/78, and the nursing notes indicate that the patient states her vision is okay and she has no epigastric pain and no pedal edema. repeat blood pressure was 151/83. at 12:50 p.m. her blood pressure was 172/90. at 1:30 p.m. her blood pressure was 164/86, and at 1:55 p.m. her blood pressure was 138/83, and at 4:00 p.m. her blood pressure was 141/74 (per nursing notes). the patient was evaluated by the chief resident. preeclampsia labs were sent, and physical exam was performed. the physical exam revealed that her heart was regular in rate and rhythm. the chest was clear to auscultation. the abdomen was soft and nontender. there were no masses. the incision was clean, dry, and intact. there was scant lochia noted. on her extremities there were 1+ deep tendon reflexes noted throughout, and her extremities were nontender. her neurologic exam at that point was normal, revealing extraocular movements intact, no nuchal rigidity, a supple neck, anicteric sclerae, and cranial nerves ii through xii were grossly intact without focal deficits. laboratory data: laboratory exams were sent, and they revealed the following. the times of these laboratory tests were 1:00 p.m. white blood cell count was 8.5, hemoglobin was 13.8, hematocrit was 39.0, and platelet count was 330,000. a urine test was sent, and the urine test revealed trace proteinuria, a large amount of blood (likely due to contamination from lochia), and negative for ketones. the liver function tests were normal revealing an alt of 23 and a uric acid of 4.7. the protein/creatinine ratio that was sent at 1:00 o'clock in the afternoon revealed a protein/creatinine ratio of 0.3, and serum creatinine was 0.5. hospital course: upon her initial evaluation, the patient had relative hypertension and her laboratory exam showing normal preeclampsia labs. therefore, the decision was made to have the patient evaluated by both neurology as well as anesthesiology staff to determine more clearly the etiology of headache. initial evaluation by anesthesiology was suspicious for spinal headache, and therefore, a plan was formulated to administer a blood patch. however, when anesthesia staff began making preparations for blood patch, the patient began reporting visual changes, and therefore, neurology was asked to evaluate the patient as soon as possible. neurology staff arrived promptly and began their evaluation. in the course of performing a funduscopic exam on the patient the patient was noted to have generalized tonic-clonic seizure activity. the patient was attended by the neurologist during the seizure. the patient's primary obstetrician was being covered on this day by another attending on labor and delivery; however, the primary obstetrician was coincidentally on labor and delivery attending to another urgent issue and was called in and was made aware of the events in gyn triage, and additional nursing as well as anesthesia staff were summoned for. the patient had had an iv line placed. however, this iv line was functioning very poorly. as the patient was noted to have seizure activity, magnesium sulfate was called for urgently. however, the iv site that had been placed previously was noted to be nonfunctioning. as soon as the seizure activity ceased the patient had a postictal state that was combative, and there was concern for the patient hurting herself. additionally, as the neurology staff was in attendance at this time, neurology felt strongly that the patient needed to - as a top priority - go to the ct scan area in order to determine the cause of the headache and seizure, and most importantly determine whether the patient urgently needed to go to the operating room. in view of the patient's combative postictal state, the decision was made with obstetrician as well as together with neurology to administer ativan intramuscularly as it was impossible to control the patient without sedating her. simultaneously, the icu staff was summoned for and arrived quickly. the icu staff, the anesthesia staff, the neurology staff, as well as obstetrical staff chief resident and several nurses were present trying to prepare the patient for the neurologist recommendation for immediate ct scan. consideration was made for transferring the patient to the intensive care unit; however, the intensive care unit staff felt that she needed to be sedated prior to this transfer. the anesthesia staff tried very hard to insert iv access in order to be able to give the patient intravenous medications including magnesium, however, this was extremely difficult to do given the patient's postictal state and the very strong movements of her arms and legs. for this reason - and again in conjunction with the other services - the decision was made to give the patient ativan to try to get her postictal state under control; and as a second priority to get the patient to the ct scanner in order to get imaging performed. we planned on giving the patient magnesium sulfate, however, it was impossible to do this given the fact that there was no iv access at that point. the patient went to ct scan and had a 22-gauge iv placed after 10 mg of ativan were given. a 22-gauge iv was able to be placed in the patient's arm, and the patient was urgently brought to ct scan so that contrast could be infused through this only intravenous access in order to determine whether the patient needed to urgently go to the operating room. there was additional concern that before the patient arrived in the icu that given the fact that the patient had received a total of 10 mg of ativan in order to sedate her that the addition of magnesium without adequate iv access could unacceptably increase the risk for respiratory depression in this patient. the patient had received the majority of this ativan intramuscularly and there was concern that with the poor intravenous access that the patient could become heavily sedated respiratory wise and that we wanted to make sure that the patient was in the intensive care unit setting before giving additional medication that could sedate her respiratory system. the patient was brought to the ct scan suite, contrast was infused, and the neurosurgeons were called. the on the initial ct scan showed that there was a question of a subarachnoid hemorrhage. the patient was seen by neurosurgery and neurology, and the patient was immediately transferred to the intensive care unit. at this point, there was a discussion among the obstetrical staff. the chairman of the obstetrical department was , and there was a discussion regarding the further management of this patient. the impression of the neurology staff and the intensive care unit staff was that the images and the clinical picture were consistent with posterior reversible leukoencephalopathy syndrome, and neurology felt strongly that the patient should receive prophylaxis for further seizures using dilantin. on arrival in the intensive care unit dilantin was begun, and the patient received central line access. further tests were completed in the intensive care unit including a lumbar puncture that eventually showed negative results, except that there was some blood in the cerebrospinal fluid which was consistent with a subarachnoid hemorrhage. the impression was that the clinical picture was consistent with posterior reversible encephalopathy syndrome, and we discussed once again the decision for magnesium prophylaxis. the decision was made at that point (in collaboration with neurology, intensive care unit staff, maternal fetal medicine, and general obstetrics staff) to not give magnesium sulfate as the suspicion at this time was that the patient had posterior reversible encephalopathy syndrome. the patient was intubated prophylactically in the intensive care unit as she had received ativan and there was concern about airway protection. on the second day of admission, the neurology staff requested that the obstetrical staff consider that the patient be transferred to the neurological icu (which is on the ). opinion was sought from the chairman of the obstetrical department, the maternal fetal medicine consultant, dr . a detailed conference was undertaken with dr. of neuroradiology regarding his most specific impression of the differential diagnosis, and together the impression was that the patient had posterior reversible encephalopathy syndrome, and therefore the decision was made that the patient should be transferred to the neurology intensive care unit so that she could have continuous eeg monitoring and intensive neurological oversight. the patient was transferred on the 2nd day of her hospitalization to the neurology icu on the and was observed to have no further seizure activity. the following day,the patient was extubated. upon extubation did report that she still had a headache and also noted some persistent visual deficits. the patient continued to improve and was transferred to the stepdown unit after the 4th day. the patient continued to improve and had a subsequent mri that showed that the initial changes on the mri were resolving. the patient was discharged home on with followup by visiting nurse and also with the obstetrical social worker. the final on the mri that was done on admission showed extensive cortical and subcortical white matter lesions which could be a manifestation of reversible leukoencephalopathy; though infectious and even neoplastic etiologies could be considered. the final on the mri the day before discharge from the hospital showed in the interval since the prior/previous examination there had been marked improvement in most areas of prominent t2 hyperintensity involving high bilateral frontal, right parietal, bilateral occipital lobes, and cerebellum; although a residual amount of t2 hyperintensity remained. the impression showed marked improvement of diffuse white matter hyperintensity with residual amount remaining and showed evidence of residual blood within the sulci on flare images. discharge disposition: the patient was discharged home on . condition on discharge: noted to be in good condition. discharge follow-up plans: to follow up with neurology as well as with her primary obstetrician the following week after discharge. , m.d. procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified spinal tap incision of lung insertion of endotracheal tube diagnoses: urinary tract infection, site not specified other encephalopathy other complications of puerperium, postpartum condition or complication infections of genitourinary tract
