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: no known allergies / adverse drug reactions attending: chief complaint: elective admit for resection of right frontal tumor major surgical or invasive procedure: r frontal craniotomy for resection of tumor history of present illness: the patient is a 65 year old right handed man who initially presented with a generalized convulsive seizure while driving. a second episode occurred upon arrival to the ed. he has subsequently been found to have a right frontal white matter brain lesion and retroperitoneal lymphadenopathy, most concerning for malignancy. the patient and his wife deny him ever having shown seizure activity including clonus or staring spells. he reports being healthy and has not had constitutional symptoms including fevers, rigors, night sweats, or weight loss. he has had no recurrence of seizures and now feels well. we are being consulted for consideration of a brain biopsy of the right frontal lesion. past medical history: hld hypothyroidism social history: ex smoker 20 years ago family history: no seizures or cancers physical exam: general: awake, nad, seated in bed comfortably head: nc/at, no scleral icterus, no oropharyngeal lesions neck: supple, no nuchal rigidity extremities: warm, no edema, palpable radial/dorsalis pedis pulses skin: no rashes or lesions neurologic examination: - mental status - awake, alert, oriented x 3. recalls a coherent history. registration and recall . concentration maintained when recalling months backwards. follows two step commands, midline and appendicular. language fluent with intact repetition and verbal comprehension. normal prosody. no paraphasic errors. high and low frequency naming intact. no dysarthria. no apraxia or neglect. - cranial nerves - perrl 3->2 brisk. vf full to number counting. eomi, no nystagmus. v1-v3 without deficits to light touch bilaterally. no facial asymmetry. hearing intact to finger rub bilaterally. palate elevation symmetric. ] scm/trapezius strength 5/5 bilaterally. tongue midline. - motor - normal bulk and tone. no pronation, no drift. no tremor or asterixis. = ] l 5 5 5 5 5 5 5 5 5 5 5 r 5 5 5 5 5 5 5 5 5 5 5 - sensory - no deficits to light touch bilaterally. - reflexes = ] l 2 2 2 2 2 r 2 2 2 2 2 plantar response flexor bilaterally. - coordination - no dysmetria with finger/foot mirrored movements. pertinent results: nc ct head 1.4-cm hyperdensity in the right frontal lobe with surrounding vasogenic edema. this is a nonspecific imaging finding and the differential diagnosis includes tumor, encephalitis or venous ischemia. primary traumatic injury is felt to be much less likely. the imaging findings could be consistent with lymphoma. mri head c/s contrast right frontal signal abnormality with a central portion of restricted diffusion is not typical for an infarction and is predominantly involving the white matter. the restricted diffusion could favor infiltrative lesion with high cellularity such as lymphoma or encephalitis. nc ct head status post open biopsy from a right frontal approach with a small amount of subarachnoid blood; right frontal sulcal effacement and vasogenic edema similar to , head ct. mri head c/s contrast 1. right frontal lobe lesion redemonstrated for surgical planning, with faint ill-defined enhancement, surrounded by vasogenic edema. please see the prior mr head study for additional details. brief hospital course: pt was admitted to the neurosurgery service and underwent an elective right frontal craniotomy for resection of tumor. he tolerated this procedure very well with no complications. his neurologic status was preserved without any noted deficits. post-operatively, he was transferred to the neurology floor for further care including neurologic status monitoring. he was discharged on in good condition without neurologic deficits. he will followup with dr. on and in the brain clinic on for further management. medications on admission: levothyroxine 25 mcg po daily atorvastatin 20 mg po daily levetiracetam 1500 mg po bid pantoprazole 40 mg po daily cepacol every 4 hours as needed for sore throat discharge medications: 1. simvastatin 40 mg tablet sig: one (1) tablet po daily (daily). 2. levothyroxine 112 mcg tablet sig: one (1) tablet po daily (daily). 3. acetaminophen 325 mg tablet sig: 1-2 tablets po q6h (every 6 hours) as needed for fever/pain. 4. levetiracetam 500 mg tablet sig: three (3) tablet po bid (2 times a day). discharge disposition: home discharge diagnosis: right frontal lobe brain mass nos discharge condition: good 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; no lifting, straining, or excessive bending. ?????? you may wash your hair only after sutures and/or staples have been removed. if your wound closure uses dissolvable sutures, you must keep that area dry for 10 days. ?????? you may shower before this time using a shower cap to cover your head. ??????
