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: contrast-enhanced images of the chest were performed following the administration of 150 cc of iv optiray. nonionic iv contrast was used per the patient's history of allergies. ct of the chest with contrast: there is extensive centrilobular emphysema throughout both lungs. superimposed on this is diffuse ground-glass opacity in both lungs, particularly within the lower lobes. in addition, several nodular opacities are seen in both lungs, mostly at the bases, the largest of which measures 2 cm and is at the left base. also, increased patchy opacities are seen in both lower lobes as well. the heart is upper limits of normal in size. the pericardium is normal. coronary artery calcifications are noted. severe calcific atherosclerotic disease of the thoracic aorta is appreciated. there is no mediastinal, hilar, or axillary lymph node enlargement. an et tube is in good position above the carina. an ng tube is seen coursing through the esophagus and entering the stomach. there is a minimal right sided pleural effusion and bibasilar dependent atelectasis. impression: 1) diffuse severe emphysema. 2) diffuse superimposed ground-glass and interstitial opacities. this likely related to superimposed pulmonary edema secondary to cardiac failure. 3) several nodular opacities, most prominent at the lung bases. confirmation of resolution of these nodular opacities after treatment is recommended to rule-out possible metastatic disease. conversely, these nodular opacities along with patchy opacities seen in the lower lobes may relate to superimposed aspiration and/or pneumonia. 4:27 pm ct chest w/contrast; ct abdomen w/contrast clip # ct pelvis w/contrast; ct 150cc nonionic contrast reason: eval abscess, peritonous,infectious foci. s/p colectomy admitting diagnosis: sepsis contrast: optiray amt: 150 ______________________________________________________________________________ final report (revised) ct abdomen and pelvis - dictated as an addendum (chest ct reported earlier) indication: post-op partial colectomy. fever. assess for abscess. technique: helical axial images were obtained of the abdomen and pelvis with oral and intravenous contrast. 150 cc of optiray contrast was administered. non-ionic contrast was used secondary to patient's allergies. reformatted images were obtained in the coronal and sagittal planes. ct of the abdomen with iv contrast: there is a 1 cm low attenuation lesion within the dome of the liver. this is not fully evaluated on this study, but likely represents a simple cyst or hemangioma. the liver is otherwise unremarkable. the gallbladder and pancreas are normal. there is an oblong 1.1 x 0.8 cm low attenuation lesion within the periphery of the spleen. this is not fully characterized on this study, but likely represents a benign lesion. the adrenal gland and kidneys are normal. there is no retroperitoneal lymphadenopathy. there is calcification and irregularity of the aorta. a large focal plaque or thrombus is present within the aorta immediately below the level of the renal arteries. this occupies approximately 50% of the lumen of the aorta and extends approximately 2 cm in the craniocaudal dimension. there is no aneurysmal dilatation of the aorta. the stomach, small bowel, cecum, and proximal transverse colon are unremarkable. there is a distal transverse colostomy in the left mid abdomen. the patient is status post resection of what appears to be the distal transverse colon and partial resection of the left colon. a small amount of fluid is present adjacent to what appears to be the oversewn stump of the residual distal left colon. this appears to layer within the surgical resection bed and does not appear loculated. this measures approximately 3 cm x 5 cm in greatest cross- sectional dimension. there is no internal or peripheral enhancement and this is unlikely to represent an abscess at this time. the remaining distal left colon and sigmoid colon are collapsed and otherwise unremarkable. there is no free air in the abdomen. irregular soft tissue density and fat stranding is present immediately deep to the surgical staple line within the subcutaneous tissues of the mid abdomen. this is likely incidental post-op change. ct of the pelvis with iv contrast: the distal ureters are unremarkable. the bladder is collapsed and contains a small amount of air and a foley catheter. there is a small amount of layering fluid within the pelvis. the pelvic loops of small bowel are unremarkable. there are no contained fluid collections in the pelvis. (over) 4:27 pm ct chest w/contrast; ct abdomen w/contrast clip # ct pelvis w/contrast; ct 150cc nonionic contrast reason: eval abscess, peritonous,infectious foci. s/p colectomy admitting diagnosis: sepsis contrast: optiray amt: 150 ______________________________________________________________________________ final report (revised) (cont) there is scoliosis of the lower lumbar spine. there are no suspicious lytic or sclerotic lesions. ct reconstructions: reformatted images in the coronal and sagittal planes confirm the above mentioned findings. impression: 1) small amount of fluid adjacent to the left colon stump, likely post operative in nature. there is no collection suspicious for a mature abscess at this time. 2) small low attenuation lesions in the liver and spleen. these are likely benign but are not fully characterized on this study. 3) calcified irregular aorta and prominent infrarenal plaque/thrombus. 4) findings discussed with the surgical service. procedure: continuous invasive mechanical ventilation for 96 consecutive hours or more parenteral infusion of concentrated nutritional substances enteral infusion of concentrated nutritional substances other bronchoscopy diagnoses: congestive heart failure, unspecified chronic airway obstruction, not elsewhere classified acute respiratory failure bacteremia methicillin susceptible pneumonia due to staphylococcus aureus seroma complicating a procedure subendocardial infarction, subsequent episode of care colostomy status 

Answer: The patient is high likely exposed to
