7-year old DSHCooter

• RF
• There is a profound loss of abdominal detail in
  this patient.
• The only abdominal structures that can be defined
  are portions of the gastrointestinal tract and
  these are visible only due to their luminal
  contents.

  normal position.
• Granular material and some gas are visible in the
  colon.
• There is a mass effect in the cranial abdomen
  causing displacement of the colon and visible
  small intestinal segments.
• The opacity in the caudoventral abdomen may be
  due to the presence of the normal urinary bladder
  and fluid.
• RD
• Not much can be determined regarding the
  abdominal organs in this patient due to the lack
  of detail
• R/O
• Emaciation
• Free abdominal fluid
• Cranial abdominal mass
• Next
• Abdominal ultrasound

  lucencies throughout the abdomen that do no
  appear to be present in intestinal structures.

• RF
• Large soft tissue mass in the sublumbar region
  depressing the colon ventrally.
• Coarse reactive bony response on the ventral
  surface of L5.
• Bony response of T12 and T13 sclerosis, lysis
  and an indistinct opaque intervertebral foramen.
• RD
• Sublumbar mass with bony reaction of L5 and T12,
  T13
• R/O
• Neoplastic process of the urinary bladder or
  prostate gland with metastasis to the sublumbar
  lymph nodes and multiple vertebrae.

6-year old Welsh Springer Tory

• RF
• Partial loss of serosal detail.
• Some distension of abdomen.
• Poorly defined soft tissue mass depressing the
  colon ventrally on the lateral film, difficult to
  visualize on the VD film.
• Transitional last lumbar vertebrae
  lumbarization of the sacrum and has 8 lumbar
  vertebra.
• RD
• Free peritoneal fluid
• Probable mass in caudal abdomen

10-year old FS Fox TerrierSparkie

• RF
• Massive abdominal distension.
• Virtually the entire abdomen is occupied by a
  large mass of fat opacity, displacing most of the
  organs cranially.
• On the lateral view there are two masses in the
  caudal abdomen, noted overlying each other on the
  VD film to the right.
• There is a displaced urinary bladder seen as a
  large, round soft tissue structure in the pelvic
  canal, constricting the colon, which is seen as a
  thin stripe of gas.
• The thoracic cavity is very small and is felt to
  be secondary due to the massive abdominal
  enlargement (Pickwickian syndrome).
• Multiple IV disc spaces are slightly narrowed and
  the hips are very arthritic.
• RD
• Massive intra-abdomianl lipoma
• Next
• Weight reduction
• Surgery

  provided. On PE a mass was palpated in the
  abdomen.

• RF
• There is an increase in splenic size or
  displacement of the spleen.
• The stomach is distended and contains fluid, gas
  and small fragments of mineral material.
• There is a large poorly defined mass of soft
  tissue opacity in the central abdomen causing
  displacement of the small intestinal segments and
  colon.
• The cardiac silhouette and pulmonary vessels are
  small.
• One kidney is visible and it is of normal length
  but may be wider than normal.
