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: history of present illness: the patient is a 48 year-old gentleman with small cell lung cancer diagnosed in who is status post chemotherapy and external beam radiation who presented with low back pain, and right leg pain and numbness earlier this month. an mri scan showed an intradural lesion at the l1-l2 level and lesion on the right at l4. he underwent external beam radiation and since then his pain has essentially resolved. he still has some numbness in the right foot. he did have an mri of the brain, which showed a 4.5 cm right frontal enhancing lesion consistent with a single metastasis with surrounding edema. he is admitted for excision of this metastatic tumor. past medical history: small cell lung cancer diagnosed in . physical examination: as of when his history and physical was done his temperature was 101.5. pulse 120. blood pressure 147/92. respiratory rate 16. sats 98% on room air. the patient's examination was significant for some mild diffuse crackles and also rhoncherus breath sounds on the right upper lobe. neurologically the patient was alert and oriented times three. cranial nerves ii through xii were intact. muscle strength was 5 out of 5 in all muscle groups. his sensation was decreased in the right lower extremity to the foot and also the lateral aspect of the right lower extremity. the patient's toes were upgoing on the right and downgoing on the left. his reflexes were unable to be appreciated on the right lower extremity. other reflexes were 2+ throughout. laboratory: white blood cell count 6.1, hematocrit 29.3, chem 7 unremarkable. chest x-ray showed extensive volume loss in the right upper lobe with a right apical pleural based opacity, prominent right hilar region and overlying cushion of pneumonia. a magnetic resonance scan revealed an l1-l2 2.5 by 1 cm enhancing solid mass inside the spinal cavity displacing the cord to the left. at l4 there was enhancing epidural mass with no compression and minimal disc bulge at l5-s1. chest ct, which had been done in revealed a slight decrease, but present right upper lobe nodule in the addition to tiny nodules predominantly involving the right upper lobe. hospital course: the patient was admitted to the oncology service at that time and was discharged in stable condition after treatment for pneumonia and radiation to his spine. , m.d. dictated by: medquist36 procedure: other operations on extraocular muscles and tendons other excision or destruction of lesion or tissue of brain computerized axial tomography of head other immobilization, pressure, and attention to wound diagnoses: pneumonia, organism unspecified thrombocytopenia, unspecified secondary malignant neoplasm of brain and spinal cord malignant neoplasm of bronchus and lung, unspecified compression of vein secondary malignant neoplasm of bone and bone marrow sympatholytics [antiadrenergics] causing adverse effects in therapeutic use 

Answer: The patient is high likely exposed to
