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: patient recorded as having no known allergies to drugs attending: chief complaint: nausea/vomiting major surgical or invasive procedure: ct guided stereotactic aspiration of right cerebellar hemorrhage history of present illness: this is an 89 year old male with a history significant for metastaic melanoma, on coumadin (inr 4.9), 81 mg aspirin, with recent lumbar laminectomy doing rehab at home. the night prior to presentation, he was feeling dizzy. in the middle of the night he was grasping at the door frame, and kept waking every half hour to vomit. he woke and felt nauseous and vomited. that morning, he had a fall at home and hit the right side of the head, no loc. he was taken to by ambulance. past medical history: primary melanoma in with right axillary dissection and radiation - discontinued due to r arm swelling. l-sided axillary mass w/ excision of chest wall tumor and l-axillary dissection and s/p 10 treatments xrt recently. s/p a lumbar spinal laminectomy in , has been unsteady and using walker at home. prostate cancer diabetes social history: he lives in . he used to work as an attorney. he is currently in rehabilitation. he lives with his wife. has four children and five grandchildren. family history: nc physical exam: on admission: t 97.2 bp 126/66 p 80s r 16 spo2 97% gen: elderly male lying on bed in c-collar, nad heent: non-icteric, atraumatic cv: rrr, no murmurs pulm: ctabl abd: soft, nt, nd ext: rue swelling significantly larger then l ms: alert, oriented to , date, and name. speech was slurred, slight dysarthria, but was fluent, no paraphasic errors, no anomia, no evidence of neglect, apraxia. cn: pupils b/l to light, vff to confrontation, eomi w/ significant r-beating nystagmus on lateral gaze, facial sensation intact, smile symmetric, hearing intact b/l, palate symmetric, tongue midline. motor: increased tone b/l at le, significant swelling of the r arm, strength full throughout reflexes: normal throughout, toes flexion b/l coordination: significant dysmetria w/ b/l arms and legs on fnf testing and on hts testing sensation: intact to light touch and pinprick throughout gait: not tested on discharge: expired pertinent results: 08:33am pt-46.0* ptt-33.0 inr(pt)-4.9* 08:33am plt count-156 08:33am neuts-89.7* lymphs-6.3* monos-3.7 eos-0.1 basos-0.1 08:33am wbc-5.8 rbc-3.99* hgb-11.0* hct-33.4* mcv-84 mch-27.7 mchc-33.1 rdw-15.0 08:33am ctropnt-0.02* 08:33am estgfr-using this 08:33am glucose-321* urea n-32* creat-1.3* sodium-131* potassium-4.9 chloride-97 total co2-23 anion gap-16 cta head and neck 1. right cerebellar hemisphere hemorrhagic lesion, better seen on the recent non-contrast head ct. no evidence of underlying avm or aneurysm. this could represent a parenchymal hematoma in the setting of the patient's anticoagulated status or a metastasis from his melanoma. 2. no cervical spine fracture. extensive degenerative changes. 3. post-radiation/post-surgical changes in the right lung apex and right axilla partially visualized. ct head : large (~ 6.0 x 4.8 cm) ill-defined hyperdense collection in the right cerebellar hemisphere with hematocrit levels, consistent with hemorrhage, likely subacute. local mass effect as described, with leftward shift of the right cerebellar hemisphere and concern for early tonsillar herniation. differential diagnosis includes traumatic injury, hemorrhagic metastatic disease given history of melanoma or vascular abnormality. mri/mra or cta should be considered for further evaluation. cxr : ap supine portable view of the chest is obtained. low lung volumes somewhat limit evaluation as well as slight patient rotation to the right. clips in the right axilla are noted. the lungs appear clear bilaterally, aside from area of known scarring in the right lung apex. the cardiomediastinal silhouette appears unremarkable. old healed right lower rib fractures are again noted. no acute fractures are seen. impression: no acute traumatic injuries evident. mri brain : 1. nodular area of enhancement along the lateral margin of the large infratentorial hemorrhage is suggestive of an underlying mass, compatible with metastatic disease. 2. new small focus of hemorrhage in the left anterior inferior cerebellar hemisphere. new supratentorial subarachnoid hemorrhage in the sylvian fissures and the occipital sulci. 3. intraventricular hemorrhage. stable partial effacement of the fourth ventricle with stable enlargement of the lateral and third ventricles. 4. the cerebellar tonsils efface the csf space in the foramen magnum but do not herniate below the foramen magnum. ct head compared to head ct, increased size and distribution of right cerebellar hemorrhage with increased surrounding edema and mass effect; however, lesion is stable compared to more recent mri. increased hydrocephalus, particularly evident in the left lateral occipital . doppler us : no new acute deep vein thrombosis identified. chronic, occlusive subclavian clot is seen, the appearance of which is stable since the torso ct of . a single tiny venous structure identified in the region of the subclavian represents either collateral flow or is extremely diminutive vessel lumen. head ct: impression: decreased size of right cerebellar hemorrhage with decreased associated mass effect and reestablished patency of the fourth ventricle. stable hydrocephalus. new post-operative extra-axial pneumocephalus and air within pre-existent clot cavity. head ct: impression: no significant interval change. 1. similar size of right cerebellar hemorrhage. 2. stable hydrocephalus. 3. bilateral frontoparietal and occipital subarachnoid hemorrhage which appears similar. 4. interval decrease in size of extra-axial pneumocephalus, and stable air within preexisting clot cavity. head ct: 1. interval worsening in the obstructive hydrocephalus. 2. stable bilateral frontal, parietal, and occipital subarachnoid hemorrhage. 3. stable right cerebellar hemorrhage with slight redistribution of blood due to positioning. brief hospital course: mr. was admitted to sicu under the care of dr. on for evaluation of right cerebellar hemorrhage. he had an mri on the evening on which revealed tumor, presumed to be metastatic melanoma. he required zyprexa for this study bu was still lethargic and disoriented many hours later. ct revealed extension of the hemorrhage. he was slowly becoming for alert. a family meeting was held with dr. and his wife and four children. surgical nd conservative treatments were discusses. dr. of the neuro oncology group reviewed the images and was in favor of surgery. dr. also met with the family to discuss the potential for a ct guided stereotactic biopsy and spiration. they agreed to procede. on , he was more lethargic and confused and he was taken to the or. surgical frame was placed on pre-op and he had a ct scan. biopsy and aspiration was performed without complication. approximately 40ml was aspirated. the patient remained intubated and in the pacu overnight. post op head ct revealed residual hematoma but significant evacuation and decompression of 4th ventricle. on pod#1 a repeat head ct was performed and stable. he was weaned from the neosynephrine and extubated. pt's exam was stable but he remained lethargic. he was transferred to icu for close neurological observation. the family was updated and plan was to place evd if hydrocephalus were to worsen vs. no intervention if hemorrhage were to worsen. the patient's code status was changed back to dnr/dni. on pod#2 the patient became less verbal. a head ct was performed revealing extension of the hemorrhage. the family was updated and decided that no further intervention would be performed. upon their arrival to the icu, the patient was made cmo. on , patient passed away with family at bedside. medications on admission: uroxatral 10 mg daily glyburide 5 mg daily lisinopril 5 daily metoprolol tartrate 25 mg daily omeprazole 20 mg daily simvistatin 40 mg daily warfarin 2.5 daily aspirin 81 mg daily discharge medications: none discharge disposition: expired discharge diagnosis: cerebellar tumor cerebellar hemorrhage hydrocephalus intraventricular hemorrhage brain compression discharge condition: expired discharge instructions: expired followup instructions: expired procedure: other cranial puncture closed [percutaneous] [needle] biopsy of brain other immobilization, pressure, and attention to wound diagnoses: unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled coronary atherosclerosis of unspecified type of vessel, native or graft secondary malignant neoplasm of other specified sites percutaneous transluminal coronary angioplasty status intracerebral hemorrhage secondary malignant neoplasm of brain and spinal cord malignant neoplasm of prostate long-term (current) use of anticoagulants personal history of venous thrombosis and embolism secondary and unspecified malignant neoplasm of lymph nodes of axilla and upper limb cerebral cysts
