• 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.

• 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.

• 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

• 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

• 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

• 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
