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 axial images of the abdomen and pelvis were obtained with iv contrast. 150 cc of optiray contrast was used. nonionic contrast was used secondary to patient allergies. comparison: . abdomen ct with iv contrast: a small right pleural effusion with right basilar atelectasis is appreciated. the left lung is clear. there is uniform enhancement of the liver. mild intrahepatic ductal dilatation is present, consistent with post-liver transplant. no focal masses. there is a fluid collection with an enhancing rim located immediately medial to the liver and superior to the porta hepatis. several areas of small gas bubbles are present within this fluid collection. the pancreas is unremarkable. the spleen is enlarged. the adrenals and kidneys are normal. a feeding tube is present which passes through the stomach and into the proximal jejunum. a single percutaneous biliary stent is present with the tip at the porta hepatis. the stomach, small bowel, and large bowel are unremarkable, without focal wall thickening or bowel dilatation. ascites is present, and is unchanged since the prior exam. pelvis ct with iv contrast: the distal ureters, rectum, and uterus are unremarkable. there is no abnormal lymph node enlargement within the pelvis. the osseous structures are unremarkable. impression: 1. perihepatic fluid collection with an enhancing rim capsule and containing air. this is new in comparison to the prior study. 2. ascites, unchanged in the interval. 3. small right pleural effusion with right basilar atelectasis.

Answer: The patient is high likely exposed to
