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: headache, loc major surgical or invasive procedure: : left burr hole and placement of external ventricular drain(evd) : removal of evd, cyst aspiration, catheter placement. : scalp wound revision history of present illness: 65m presented to osh this am after complaining of headache on . per reports from ed records, and parents(with whom he resides), he then went upstairs to the bathroom when a "thump" was heard. his mother went upstairs into the bathroom and found him on the floor, incontinent of urine and unresponsive. she then called 911, and was taken to osh. upon presentation to osh, he was found to be hypertensive to 230/150, started on nipride. his head was scanned and revealed a "massive head bleed, without midline shift". he was then subsequently transferred to for definitive care and neurosurgical evaluation. in the duration of transfer, per ems noted, started decorticate posturing and they began infusion of 25 gm mannitol iv. past medical history: none; per mother social history: resides at home with parents family history: non-contributory physical exam:

level of the mid brain with blood filling the lateral, third, and fourth ventricles. dilatation of the ventricles and transependymal migration of csf is consistent with obstructive hydrocephalus. there is 8 mm rightward shift of normally midline structures. grey-white matter differentiation remains preserved. secretions in the nasopharynx may be related to ng tube. ethmoidal, maxillary, and sphenoidal mucosal thickening is mild. the mastoid air cells remain normally aerated. the surrounding osseous structures are unremarkable. note is made of prominent csf space in the suprasellar cistern,which can be seen with marked obstructive hydrocephalus, but a suprasellar arachnoid cyst can have a similar appearance. cxr : findings: there is an endotracheal tube whose tip is approximately 2.4 cm above the level of the carina. there is a nasogastric tube that courses below the diaphragm and lies within the stomach. the stomach, however, remains moderately distended with gas. the lungs are clear. there is no evidence of congestive heart failure or pneumonia. there is no evidence of pleural effusions or pneumothorax. the cardiac and mediastinal contours are normal in appearance. the visualized osseous structures are unremarkable. mri head +/- : impression: 1. extensive intraventricular hemorrhage involving all the ventricles as described above, predominantly in the acute stage with a small subacute component. 2. obstructive hydrocephalus, with dilatation of the left lateral ventricle and moderate on the right. 3. while there is no obvious abnormal enhancement noted within the area of hemorrhage, small neoplastic or vascular causes within the ventricles cannot be excluded. repeat evaluation can be considered after evacuation or resolution of the hematoma. 4. subarachnoid hemorrhage, in both cerebral hemispheres. given the presence of intraventricular and subarachnoid hemorrhage, patient needs further evaluation to exclude a vascular cause like an aneurysm by ct angiogram. the intracranial arteries are not adequately assessed on the present study. displacement of the right internal carotid artery termination and the anterior cerebral arteries on both sides related to the enlarged ventricles is noted. cta head : impression: 1. no evidence of aneurysm, arteriovenous malformation or other vascular abnormality as source of massive intraventricular hemorrhage. there is also no focal contrast extravasation to suggest a bleeding source or risk of continued hemorrhage. 2. only scant subarachnoid hemorrhage, unchanged, with no evidence of cerebral vasospasm. 3. extensive intraventricular hemorrhage, with severe obstructive hydrocephalus, unchanged. 4. persistent dilatation of the left lateral ventricle, despite the ventriculostomy catheter, whose tip may abut or even transgress the lateral ventricular wall. 5. persistent disproportionate and cystic-appearing dilatation of the 3rd ventricle (despite presence of lateral ventriculostomy) which may, effectively, be "trapped." ct sinus : impression: panmucosal thickening within the paranasal sinuses, increased compared to the ct of . obstruction of the ostiomeatal units bilaterally. extensive nasal secretions. left frontal ventricular catheter appears to terminate in brain parenchyma as discussed on concurrent head ct. head ct : findings: a ventricular catheter entering from a left frontal approach appears to terminate within the left frontal lobe (2:13). the left lateral ventricle remains extremely dilated but not significantly changed compared to the examination two days prior. large amount of blood within the lateral ventricles and the third ventricle is essentially unchanged. scattered foci of subarachnoid hemorrhage throughout both cerebral hemispheres are unchanged. thickening of the ethmoid, sphenoid, and maxillary sinuses of the mucosal surface is stable compared to the most recent exam. mri : findings: there has been a reduction in the volume of hemorrhage present within the bodies of the lateral ventricles. the large suprasellar cyst, previously identified, has enlarged dramatically in this interval. a left frontal ventricular catheter is again identified. no pre-contrast imaging was performed. it is unclear whether hyperintensity of the lateral ventricular margins represent enhancement or subacute hemorrhage. headct impression : 1. status post drain placement in the previously noted large suprasellar/prepontine cyst, change in the shape of the cyst, and possible mild or no significant change in the overall size. close f/u. 2. extensive intraventricular, some amount of subarachnoid and subdural hemorrhage partially imaged and not significantly changed. head ct :impression: 1. no change in position of left frontal approach catheter terminating within a large cyst centered in the suprasellar/pre-pontine cistern. 2. no definite change in size of cyst. 3. similar extensive hemorrhage within the lateral ventricles, and smaller subarachnoid hemorrhage in bilateral sylvian fissures. 4. slight decrease in degree of hemorrhage within the cyst or third ventricle. brief hospital course: the patient arrived to as transfer from osh for a significantly sized intracerebral hemorrhage. on initial exam, he was following some commands after receiving 20gm mannitol en route to hospital. he was emergently take to the or for evd placement after ct findings. his exam post drain did improve and mri showed no obvious mass. ct showed with decrease in size of ivh and stable icps. cta of head was done showed no avm, however bleeding was likely due to arachnoid cyst. on , he was again taken to the or for endoscopic cyst aspiration and rickham catheter placement. post-operatively he continue to improved markedly. on his examination on , he was found to have gross visual field deficits and ophthalmology was consulted. he was found to be blind with some light awareness bilaterally. this was thought to be secondary to vitreous hemorrhage of unclear origin. he was also able to see shadows towards the end of his hospital course. ophthamology would like to see him on follow up. the patient was able to be extubated and was breathing well on his own and his diet was advanced to regular. he was eating and drinking without difficulty. he did have hyponatremia for several days for which he was placed on salt tablets and kept on a fluid restriction. on his sodium was improving and the salt tabs were decreased. they were decreased again on and his fluid restriction was liberalized. since that time his sodium has normalized, without any recurrance of issue. guardianship was pursued. the patient continued to have daily pt while waiting for guardianship. the papers were drawn up by the legal department, signed by dr. , and given to the family on . throughout the duration of his hospital stay, mr worked daily with pt and was determined to be an appropriate rehab candidate. he was discharged to an appropriate facility on . medications on admission: none discharge medications: 1. bisacodyl 5 mg tablet, delayed release (e.c.) sig: two (2) tablet, delayed release (e.c.) po daily
