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: pfi version #1 svmc mon 7:37 pm multiple nerve sheath tumors within the spinal canal at the level of t12 through l1 which has grown in size and are causing conus compression. ______________________________________________________________________________ final report clinical history: 26-year-old female with significant past medical history of multiple schwannomas. now with new onset leg pain and paraesthesia. comparison: mr . technique: sagittal and axial short tr, short te spin echo imaging was performed along with sagittal long tr, long te fast spin echo, and stir imaging. axial long tr, long te fast spin echo imaging was performed. after administration of intravenous contrast, sagittal and axial short tr, short te spin echo imaging was repeated. findings: three nerve sheath tumors in the t12 through l1 spinal canal have all grown in size significantly since the prior examination. the superior most tumor (12:7) is causing substantial conus compression. the more caudal ones are causing compression of the cauda equina. post-surgical changes are seen at the l3 through s1 level. again noted are multiple laminectomies. a nerve sheath tumor behind the right psoas is once again evident and stable in (over) 1:40 pm mr w & w/o contrast clip # reason: evaluate for recurrent of l4 dural schwannoma admitting diagnosis: pelvic pain contrast: magnevist amt: 11 ______________________________________________________________________________ final report (cont) size. there has been resection of the large mass seen in the caudal thecal sac since the study of . there are post operative changes, with no evidence of residual tumor in this location. the small syrinx in the distal cord is not longer detected, likely effaced by the mass effect of the schwanomma. conclusion: three nerve sheath tumors within the spinal canal at the level of t12 through l1 which have grown in size. the most cephalad tumor is causing conus compression at the level of t12. these findings were discussed with dr. by dr. at 5:40 p.m. via telephone on the day of the study. procedure: imageless computer assisted surgery excision or destruction of lesion of spinal cord or spinal meninges other exploration and decompression of spinal canal other repair and plastic operations on spinal cord structures diagnoses: other chronic pain tobacco use disorder anxiety state, unspecified other constipation personal history of irradiation, presenting hazards to health myelopathy in other diseases classified elsewhere accidental cut, puncture, perforation or hemorrhage during surgical operation accidental puncture or laceration of dura during a procedure absence of menstruation schwannomatosis 

Answer: The patient is high likely exposed to
