Radiology Packet 34 GI Contrast
5 mo old M Golden Retriever“Remi” • HX = presented for evaluation of vomiting for 7 days
5 mo old M Golden Retriever“Remi” • RF • The stomach is displaced cranially and it contains a small amount of barium. • Very large barium filled loops of bowel are visible, there are far too many large loops present for this to be all colon. • Also, the “hairpin turns” and “stacking” of loops is characteristic of small bowel distension. • The bladder is displaced caudally into the pelvic canal. • RD • Small intestinal obstruction • Next • Surgery
9 yr old MC DSH “Shadow” • HX = History of vomiting, anorexia, and weight loss. Survey rads were taken as well as a systematic UGI.
9 yr old MC DSH “Shadow” • RF • On the survey films there are segments of SI which are dilated beyond normal limits with fluid and gas. • Also, there is slight reduction in mid-abdominal detail and spondylosis of L6-7-S1. • At Time 0 note the normal stomach position. • At Time 15 minutes the leading edge of the barium column widens and there are irregular filling defects here. • At Time 30 minutes more of the distal portion of the SI are dilated. • At Time 45 minutes there is continued dilation of the SI and the point of obstruction is now detected as a tapering, pointed constriction of barium seen in the mid abdomen on the lateral view and along the mid-right abdominal wall on the VD film. • At time 1.5 hours the obstruction is again evident and one segment of SI is noted to be thickened in the mid-ventral abdomen to the right. • At time 2 hours the dilated loop of bowel caused by the obstruction is clearly seen from the remaining SI. • RD • Partial mid-distal small intestine obstruction, most common cause in an older cat is a neoplastic process such as adenocarcinoma.
13 yr old FS DSH“Spotty” • HX = thirty day history of vomiting, regurgitation after ingestion of solid food
13 yr old FS DSH“Spotty” • RF • A negative contrast gastrogram was performed and the air outlines a clearly defined opaque structure in the pyloric antrum. • The structure does not change position between the 2 views indicating that it is relatively fixed in position. • There are incidental findings of luxation and degenerative joint disease of the left coxofemoral joint. • In the VD view a mineral opacity structure is superimposed with the pelvic canal, it is a type of projectile likely from a pellet gun. • RD • Gastric foreign body • Next • Surgical removal
11 yr old M Golden Retriever“Bosley” • Hx = two day history of vomiting, has a history of pica
11 yr old M Golden Retriever“Bosley” • RF • In the one hour films the pyloric region of the stomach and the descending duodenum have an abnormal appearance, the bowel lumen is narrow and has a plicated appearance. • In the VD view there is asymmetrical narrowing of the lumen of the descending duodenum which is often described as an “apple core” lesion. • The barium outlines granular material in the ascending duodenum. • In the 1 hr 45 min films there has been some further progression of a small volume of contrast into the jejunum. • RD • Delayed gastric emptying due to abnormality of the pylorus/descending duodenum • Most likely these radiographic changes are due to an infiltrative bowel lesion, intestinal adenocarcinoma is the top differential
3 mo old F GSD“Dukey” • HX = presented for regurgitation
1 yr old F Newfoundland“Chelsea” • HX = history of regurgitation and weight loss
1 yr old F Newfoundland“Chelsea” • RF • On the lateral view of the survey films there is an air lucency over the cranial mediastinum with a soft tissue opacity ventral to this. • Also, there is a thin soft tissue structure overlying the caudal vena cava. • On the VD survey film there is a widened cranial mediastinum and a linear soft tissue structure left of the spine. • On the esophogram contrast medium outlines and defines an abnormally enlarged esophagus. • RD • Megaesophagus
3 mo old F GSD“Dukey” • RF • The lateral survey film of the thorax demonstrated a large air-filled esophageal diverticulum cranial to the heart. • The trachea was displaced ventrally by the esophagus. • On the esophogram a large diverticulum was noted cranial to the heart base. • The diverticulum was created by a focal narrowing of the esophagus just cranial to the carina. • Also, the contractions in the esophagus distal to the focal narrowing appeared weak. • RD • Persistent right aortic arch • Next • Surgery
