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: r acute on chronic sdh major surgical or invasive procedure: r craniotomy for evacuation of sdh history of present illness: mr. is a 53 yo right handed man whose only past medical history is that of having presented with an atraumatic sdh in . at that time he presented with has and underwent left craniotomy for drainage of a left frontal sdh with dr. . he has no known coagulopathy and is on no anti-coagulants, including asa, at baseline (in fact he takes no meds). he now presents with about one week of having a mild ha which is over the right hemisphere and dull and aching. there is no history of prior trauma associated with this. he has no had any blurred vision but had mild nausea today. yesterday, he noticed that he was weaker on his left side (both arm and leg). this was subtle, but clearly different from the right. given his past history, he went to an osh today and was transferred to after a head ct showed an acute on chronic r fronto-parietal sdh. past medical history: l sdh social history: masters degree, works teaching english as a second language. no tob.

nonfocal exam. head incision c/d/i. pertinent results: ct head w/o contrast status post recent right frontal craniotomy and evacuation of subdural hematoma. a mixed-attenuation subdural collection persists, with additional pneumocephalus reflecting the recent surgery. this is of greatest extent anteriorly, overlying the right frontal lobe, where it measures up to 13 mm from the inner table. there is diffuse sulcal effacement in the right hemisphere, and up to 7 mm of leftward shift of the midline structures. ct head w/o contrast : impression: status post removal of right subdural drain. the right subdural collection appears increased in size particularly in the right frontal region, and there is apparent increased conspicuity of the hyperdense/acute component of this collection. close imaging and clinical followup is recommended. 05:25am blood wbc-8.2 rbc-3.75* hgb-12.2* hct-35.9* mcv-96 mch-32.5* mchc-34.0 rdw-12.1 plt ct-176 05:25am blood plt ct-176 02:00pm blood

for a r crani for evacuation of r sdh. post operatively patient was transferred to icu for monitoring. a subdural drain was placed in the or and leveled at shoulder. post op head ct showed normal post operative changes. on , exam was intact. his sd drain was removed in routine fashion and a head ct demonstrated residual right frontal hemorrhage. he remained neurologically stable and was transferred to the floor in stable condition. hematology was consulted and they determined that there was not hematological cause for his sdh. he was discharged to home. medications on admission: none discharge
