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: left facial droop major surgical or invasive procedure: : right frontal stereotactic biopsy and evd placement : right craniotomy for cavernoma resection history of present illness: 22m who is a psychology major at reports a one week history of headaches, gait unsteadiness, more difficulty texting with his left hand, feeling more tired and lightheaded, and a few hours prior to his er visit noted a left facial droop. he presented to the er where a head ct revealed a right brain mass. past medical history: denies social history: senior at , studying psychology. denies tobacco or recreational drug use. social etoh only. supportive family at bedside. family history: non-contributory physical exam: gen: wd/wn, comfortable, nad. heent: normocephalic, left facial droop extrem: warm and well-perfused. neuro: mental status: awake and alert, cooperative with exam, normal affect. orientation: oriented to person, place, and date. recall: able to name current president. language: speech fluent with good comprehension and repetition. naming intact. no dysarthria or paraphasic errors. cranial nerves: i: not tested ii: l pupil 4mm, r pupil 3mm, both reactive. visual fields are full to confrontation. iii, iv, vi: extraocular movements intact bilaterally without nystagmus. v, vii: l facial droop viii: hearing intact to voice. ix, x: palatal elevation is asymmetric, uvula deviates to right. : sternocleidomastoid and trapezius normal bilaterally. xii: tongue appears to deviate to left. motor: normal bulk and tone bilaterally. no abnormal movements, tremors. strength full power throughout. slight l pronator drift sensation: intact to light touch coordination: normal on finger-nose-finger, rapid alternating movements physical exam upon discharge: ambualtory, awake alert oriented x 3, perrl slight left facial droop, slight left drift pertinent results: head ct: impression: predominantly hyperdense intra-axial mass abutting the third ventricle which is concerning for malignancy and correlation with mri is advised to further evaluate/characterize. internal hyperdensity with apparent fluid level suggests the possibility of internal hemorrhage. findings were discussed with dr. at the time of initial review. brain mri: impression: there is a large mass predominantly midline and to the right in the region of the third ventricle, right anterior thalamus, internal capsule and displacing surrounding structures. whether this mass arises from the third ventricle or the brain parenchyma adjacent to the third ventricle is indeterminate. the signal of the mass is complex with significant t1 intrinsic hyperintensity and significant gradient signal abnormality involving the entire lesion. there are also focal areas of fluid-fluid levels and t2 isointensity of the lesion itself. given the complex signal characteristics, the differential diagnosis is broad although a cavernoma arising adjacent to the third ventricle is favored. other differential considerations include third ventricular tumors. less likely, a craniopharyngioma can extend into the third ventricle, but there is no suprasellar cistern extension. cta head: 1. no evidence of aneurysm, arteriovenous malformation or av fistula. 2. the lesion in the region of the right thalamus is unchanged in size, appearance and mass effect. 3. moderate prominence of the lateral ventricular system is unchanged compared with the most recent prior ct of the head dated . ct torso: normal ct of the chest, abdomen, and pelvis, with no evidence of malignancy. ct head:1. expected post-procedural changes including mild pneumocephalus. 2. no evidence of intraventricular hemorrhage. 3. external ventricular drain from a right frontal approach with its tip near the third ventricle. mri head: impression: unchanged intracranial mass lesion centered in the midline towards the right and adjacent to the third ventricle. the differential diagnosis for this mass is broad, some considerations are possible cavernoma arising adjacent to the third ventricle, however other differential considerations including neoplasm adjacent to the third ventricle or hypothalamic region are not completely excluded. 1. expected post-procedural changes including mild pneumocephalus. 2. no evidence of intraventricular hemorrhage. 3. external ventricular drain from a right frontal approach with its tip near the third ventricle. ct head: impression: 1. increased pneumocephalus with mass effect and displacement of the frontal lobes bilaterally is concerning for possible tension pneumocephalus in the appropriate clinical setting. correlate clinically. d/w dr. by dr. on at 1pm. 2. decreased size of the hyperdense mass felt to represent a cavenroma adjacent to the third ventricle in the setting of recent resection. mri: status post resection of right thalamic lesion, likely a cavernous malformation since the previous mri of . blood products are seen in the medial portion but resection is identified on the lateral anterior portion of the previously noted lesion. there is no new hemorrhage seen. no hydrocephalus. pneumocephalus noted. head ct: status post partial resection of right thalamic lesion with similar appearance and mass effect. blood layering in the posterior of the right lateral ventricle. ventricles similar in configuration and slightly more prominent compared to mr ; however, could be due to positioning and difference in modality. head ct: impression: right craniotomy and right thalamic resection post-surgical changes, stable since . eeg: this is an abnormal continuous eeg due to the presence of nearly continuous delta slowing with attenuation of faster frequency activity seen over the right frontocentral region, consistent with an underlying structural defect with involvement of the cortical and subcortical areas. compared to the previous tracing however, the background activity has improved, with a well-organized hz alpha frequency activity seen during the most awake portions of the tracing. there were no electrographic seizures observed. brief hospital course: pt was admitted to neurosurgery for dr. , floor w/o telemetry for q4 hr neuro checks. he was started on decadron 4mg q6 hrs and keppra 500mg and ordered for a brain mri +/- as soon as possible. this was performed and revealed a brain lesion in the basal ganglia/3rd ventricle. on neuro and radiation oncology were consulted and metastatic work up was initiated. on the patient was brought to the operating room and underwent stereotactic biopsy and evd placement. surgery was without complication. post op head ct revealed expected post-operative changes. on he had left eye edema, was full strength, and was nauseaus and vomiting. hisevd was draining csf that was pink on he was lethargic but easily arousable and his iv pain meds began to be titrated on 2.28 he was stable in the sdu while awaiting further management and final pathology results. on 3.1 dr met with the patients family to discuss surgical resection of the lesion. it was deemed appropriate that he would go to the operating room on for surgical resection on 3.2 he remained stable in the sdu with improvement of his left drift, facial droop, and mental status while awaiting surgery on on he was taken to the or and underwent a right craniotomy and mass resection. his evd catheter was also replaced. this was done without complication and he tolerated it well. he was admitted to the icu for close monitoring. post op ct revealed no hemorrhage and adequate catheter placement. on he remained neurologically stable. evd cont at 10 cm h20. decadron wean was initated and his sbp was liberalized to 160. an mri was obtained which revealed expected post-operative changes with pneumocephalus. on he was noted to have what was believed to be icu delirium, family at the bedsidce, not sleeping much, ambien and benadryl tried without much effect. on his evd was clamped and his decadron was discontinued and he was seen by psych as he continued with psychosis. psych recommended discontinuing his keppra. also on he had a head ct which shwoed his ventircles were very minimally enlarged. his drain continued to be clamped and he recieed haldol overnight for agitation. it was felt that he may have had a seziure versus dystonic reaction to the haldol as his rue was extending. he had an eeg placed on the mornign of and his mental status was much improved compared to during the weekend. another head ct was done which showed no hydrocephalus and as such his evd was pulled. on the patient remained neurologically well. eeg was removed and preliminary negative for seizure activity that could correlate with his episode of delerium. he was transferred to the stepdown unit. on pt and ot were ordered for assistance with discharge planning. on he was doing well and pt/ot felt he would benefit from outpatient services. on he was deemed fit for discharge and was given instructions for follow-up medications on admission: none discharge medications: 1. butalbital-acetaminophen-caff 50-325-40
