There is free gas noted within the peritoneal cavity. There is mild thickening of the gastric antrum, as well as the first part of the duodenum. There is also free fluid seen within the peritoneal cavity. The density of the fluid in the subhepatic region and the right para colic gutter is approximately 80 Hounsfield unit and the fluid in the pelvis is approximately 30 Hounsfield units. There is suspicion for a small tract of contrast which could represent the site of viscus perforation in the region of the junction of the first and second part of the duodenum. This could also account for the increase density of the fluid in the right para colic gutter when compared to the pelvis secondary to some leakage of the oral contrast.
There is also the appearance of a duodenal diverticulum arising from the second part of the duodenum projecting medially. The rest of the small bowel is unremarkable. The colon is relatively decompressed particularly the transverse and descending colon. There is no significant diverticular disease. No definite collection seen within the pelvis.
There is a calcified density in the right iliac fossa anterior to the psoas muscle which most likely represents calcified lymph node. The bladder, kidneys, spleen and adrenals are unremarkable. Small cyst seen in the lower pole of the right kidney. There is prominence of the extra hepatic common bile duct with a diameter up to 7mm which is probably within normal limits for age. The pancreas appears normal.
The lung bases appear relatively clear.
