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: penicillins attending: chief complaint: left cerebellar mass major surgical or invasive procedure: : l suboccipital crani for mass resection history of present illness: this is a 43 year old right handed male with past medical history significant for leukemia diagnoses at age 5 s/p whole body xrt, chemotherapy, and bmt who was seen in the er for dizziness. mri showed large l cerebellar mass. the patient has been feeling off balance over the last 3 weeks. he feels as though he is walking sideways. he has also felt lightheaded and has woken up in the mornings with a headache posteriorly. he was seen by a covering pcp yesterday who ordered an outpatient mri head with contrast. this showed a large enhancing mass involving nearly the entire left cerebellar hemisphere. he was immediately sent to the er at . on interrogation he recalls falling weks ago, striking his head on a radiator. he and his mother refer to a 8 years ago where he was struck from behind. imaging was done. the mother recalls some sort of intracranial hemorrhage and work up with dr. , a neurologist in . his office was contact and no records were available. past medical history: past medical history: leukemia age s/p whole body xrt, chemotherapy, and bmt transplant from his identical twin brother. hyperlipidemia, osteoporosis, low testosterone, radiation induced cataracts, lbbb with systolic and diastolic dysfunction with lvef of 45%. cardiac cath : mild systolic and diastolic left ventricular dysfunction. social history: lives with mother. in college. non-smoker. family history: non-contributory physical exam: physical exam: vitals: t 98.4;

however, allowing for this, there is persistent nodular and ring-like enhancement at the inferomedial aspect of the resection bed, highly suspicious for residual tumor. brief hospital course: mr. is a 43 yr old male who presented to the er with a 4 week history of gait inbalance and speech slurring. work up included a head ct that revealed a left cerebellar mass. he was admitted to the icu for observation and mr imaging was performed: this demonstrated a heterogeneous mass lesion at the left cerebellar hemisphere with multiple areas of irregular enhancement and areas with high signal intensity on t2, possibly related with a combination of necrosis and cystic transformation. there was significant mass effect and narrowing of the fourth ventricle, effacementof the posterior perimesencephalic cisterns and left side of the foramen magnum. the differential diagnosis included primary cerebellar neoplasm versus metastatic lesion. on he was taken to the or for a left craniotomy for tumor resection with dr. . post-operatively, the patient remained neurologically unchanged relative to the preopertive examination. he was observed in the icu for three days prior to transfer to the floor. neuro and radiation oncology were consulted to guide treatment. pt and ot therapy were consulted as well, and he was determined to be safe for discharge with outpatient therapy. he was discharged on with instructions for outpatient pt. medications on admission: simvastatin 80 mg daily, meclizine 12.5 mg daily, tylenol. bisphosphonate, azithromycin. discharge medications: 1. simvastatin 40 mg tablet sig: two (2) tablet po daily (daily). 2. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). 3. acetaminophen 325 mg tablet sig: 1-2 tablets po q6h (every 6 hours) as needed for pain. 4. metoprolol tartrate 25 mg tablet sig: 0.5 tablet po bid (2 times a day). disp:*30 tablet(s)* refills:*0* 5. butalbital-acetaminophen-caff 50-325-40 mg tablet sig: one (1) tablet po q4h (every 4 hours) as needed for headach. disp:*40 tablet(s)* refills:*0* 6. hydromorphone 2 mg tablet sig: one (1) tablet po q4h (every 4 hours) as needed for pain. disp:*40 tablet(s)* refills:*0* 7. dexamethasone 2 mg tablet sig: one (1) tablet po q12h (every 12 hours). disp:*60 tablet(s)* refills:*0* 8. omeprazole 20 mg capsule, delayed release(e.c.) sig: one (1) capsule, delayed release(e.c.) po once a day. disp:*30 capsule, delayed release(e.c.)(s)* refills:*0* 9. outpatient occupational therapy 10. outpatient physical therapy discharge disposition: home with service discharge diagnosis: left cerebellar mass: prelim pathology glioma discharge condition: neurologically stable discharge instructions: general instructions/information ?????? 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;
