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: service: history of present illness: the patient is on the neurosurgery service. the patient is a 61-year-old gentleman transferred via med-flight from after having a generalized tonic clonic seizure lasting 15 minutes. the patient has a longstanding history of melanoma, diagnosed decadron on the day of admission was out chopping wood the day prior to admission, feeling well without any problems. notes he was acting himself and seemed to be zoning out and then had a generalized tonic clonic seizure, was brought to hospital and then transferred to for further management. comfortably in bed. mental status: alert and oriented times three. naming intact. repetition intact. appropriate affect. no frontal release sign. no grasp or stout. cranial nerves 2 through 12 intact. pupils are equal, round, and reactive to light and accommodation. strength was bilaterally. no drift. normal bulk and tone with no tremor. sensory intact. deep tendon reflexes 2+/4 bilateral upper extremities, 3+/4 lower extremities. coordination intact. ct scan of the brain shows a 4 cm hemorrhage in the right femoral lobe adjacent to the metastatic lesion. the patient was admitted to the surgical intensive care unit for close monitoring. the patient was transferred to a regular floor. he was awake, alert, oriented times three following commands. eoms full. face symmetric with no drift. moving all extremities symmetrically and with full strength. he was seen by dr. on who recommended having a tumor resection and evacuation of hematoma followed by radiation. the patient on underwent a right frontal craniotomy for resection of metastatic lesion without interrupt complication. postop the patient's vital signs were stable. he was afebrile. he was monitored overnight in the recovery room where he remained neurologically stable with stable vital signs. postoperative dilantin level was 8.9. he was given an extra dose of dilantin. his dilantin level on the day of discharge was 10.8. he was discharged to home in stable condition on . his dressing was clean, dry and intact. he was neurologically intact with no drift, moving all four extremities. discharged to home with follow-up for staple removal in one week and then follow-up with dr. on with tapering decadron down to 2 mg b.i.d, dilantin 100 mg three times a day, zantac 150 mg p.o. b.i.d. the patient's condition was stable at the time of discharge. , m.d. dictated by: medquist36 d: 16:16 t: 16:27 job#: procedure: other operations on extraocular muscles and tendons other excision or destruction of lesion or tissue of brain other incision of brain diagnoses: esophageal reflux unspecified essential hypertension other convulsions intracerebral hemorrhage personal history of other malignant neoplasm of skin secondary malignant neoplasm of brain and spinal cord
