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: helical ct was performed from the lung bases through the pubic symphysis following administration of iv and po contrast. 150 cc of optiray were administered for indication of multiple allergies. 3d reconstructions were created through the abdomen and pelvis per ct enterography protocol. ct abdomen with contrast: there is moderate atelectasis at the lung bases. the gallbladder is distended, though without discrete wall thickneing or pericholecystic fluid collections. there is mild intrahepatic biliary ductal dilatation throughout all lobes. however, the common bile duct does not appear dilated at 6 mm. the pancreas is somewhat diminutive, and without pancreatic ductal dilatation or calcifications. the spleen, adrenals, and abdominal bowel loops are normal in appearance. there are multiple exophytic cysts on both kidneys, the largest in the right lower pole measuring 4.2 cm x 4.6 cm. there is no ascites. several small mesenteric and retroperitoneal lymph nodes do not attain ct critera for pathologic enlargement. there is moderate atherosclerotic disease of the abdominal aorta. incidental note is made of subcutaneous nodules consistent with injection sites. ct pelvis with contrast: enteric contrast reaches the rectum, without evidence of obstruction. the uterus and bladder are normal in appearance. the bones are unremarkable. 3d reconstructions: again noted are multiple renal cysts. there is no evidence of bowel obstruction. moderate intrahepatic ductal dilatation is noted. impression: 1. intrahepatic ductal dilatation and gallbladder distension are consistent with biliary obstruction. there are no focal signs of inflammation to suggest a complicated infection. this may relate to a recently passed stone. 2. bilateral renal cysts. (over) 2:01 am ct abdomen w/contrast clip # reason: r/o diverticulitis, abscess, cholecystitis contrast: optiray amt: 150 ______________________________________________________________________________ final report (cont) procedure: laparoscopic cholecystectomy diagnoses: coronary atherosclerosis of native coronary artery congestive heart failure, unspecified chronic airway obstruction, not elsewhere classified calculus of gallbladder with other cholecystitis, without mention of obstruction old myocardial infarction cholangitis acute pancreatitis 

Answer: The patient is high likely exposed to
