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: technique: axial images were obtained through the brain pre and post administration of 100 cc optiray. non-ionic contrast was used secondary to patient allergies. comparisons: mris dated and . findings: the patient is status post right frontal craniotomy and resection of the previously-identified tumor. there is no definitive enhancement. there is a small low-attenuation extraaxial collection overlying the right cerebral convexity which is most likely postoperative in nature. there is a small amount of increased attenuation within the surgical bed. residual tumor cannot be excluded. there is a small amount of mass effect but no shift of midline structures . no frank hemorrhage is identified. impression: 1) status post resection of right frontal lobe tumor. there is a small amount of increased attenuation in the margin of the surgical bed and a small amount of residual tumor cannot be excluded. 2) no evidence for frank hemorrhage. 3) low-attenuation extraaxial collection overlying the right cerebral convexity which is most likely postoperative subdural fluid collection. this causes contiguous cerebral sulcal effacement but no midline shift. the above findings were relayed by telephone to the emergency department immediately after completion of the study.

Answer: The patient is high likely exposed to
