mass in the mid-ventral abdomen which is
obliterating the normal splenic shadow. - Serosal detail in this area is decreased and also
the liver margin is rounded but not enlarged. - On the VD view the round mass is located in the
cranial and central abdomen and it is pushing the
transverse colon cranially, - RD

cranioventral abdomen and it appears to connect
to the large centrally located mass. - The liver is of normal size.

the caudal abdominal cavity. - The structures of the GI tract are displaced by
the mass but are otherwise normal in appearance. - RD

urethral obstruction and reported to have
frequent episodes of lethargy and episodes of
staring into space
123 yr old M Yorkshire Terrier
133 yr old M Yorkshire Terrier
143 yr old M Yorkshire Terrier
- RF
- In one lateral view the gastric axis is displaced
very far cranially indicating that the liver is
tiny. - The portion of the spleen that is visible appears
normal. - They kidneys are best seen in the lateral view
and appear approximately normal size. - Two fairly large, round mineral opacity
structures are present in the bladder as well as
some less defined mineral material. - Abdominal detail is less than normal but this is
a result of lack of abdominal fat (the animal is
very thin). - RD
- Microhepatia
- Cystic calculi
- The radiographic findings and clinical signs lead
to a single disease process portosystemic shunt
1512 yr old MC Manx catMerlin

his abdomen is tense on palpation
1612 yr old MC Manx catMerlin
1712 yr old MC Manx catMerlin
- RF
- Large soft tissue mass, mid-ventral abdomen on
the lateral view, right of midline on VD view. - The head of the spleen is large.
- There is decreased abdominal detail and the liver
is large with rounded margins. - The left kidney is irregular in shape.
- RD
- Large intra-abdominal mass which may be entirely
splenic in origin - Enlarged liver
- Mild amount of abdominal fluid
- Next
- Abdominocentesis
- Abdominal ultrasound and fine needle
aspirate/biopsy of mass - Abdominal exploratory
1811 yr old MC Mixed breed dogPal
- HX presented for evaluation of increasing
abdominal size and respiratory difficulty for the
last 7 days, a grade 3/6 heart murmur is ausculted
1911 yr old MC Mixed breed dogPal
2011 yr old MC Mixed breed dogPal
2111 yr old MC Mixed breed dogPal
- RF
- Evaluation of the cardiac silhouette is hindered
by the presence of free pleural fluid. - There is a generalized increase in pulmonary
tissue opacity due to superimposition of free
fluid. - An air bronchogram is visible overlying the
cranial cardiac margin in the lateral view and
there is a mild increase in opacity of the left
cranial lung lobe noted in the VD. - There is increased opacity in the cranial
abdominal cavity which is caused by the presence
of a mass lesion and the presence of free fluid
leading to a loss of abdominal detail. - The tail of the spleen is visible but it appears
large and has rounded indistinct borders. - The head of the spleen is not visible in the VD
view, instead a rounded structure of soft tissue
opacity is visible caudal to the stomach. - The stomach contains several mineral opacity
structures(stones). - RD
- Free pleural fluid and possible consolidation of
the left cranial lung lobe - Cranioventral abdominal mass, most likely of
splenic origin - Free abdominal fluid
226 yr old F AbyssinianHoney Bun
- HX history of episodic vomiting and now anorexia
236 yr old F AbyssinianHoney Bun
246 yr old F AbyssinianHoney Bun
- RF
- There is a discrete mineral opacity, irregular,
noted over the liver within the region of the
gall bladder. - Two discrete, smaller foci of mineralization are
noted on the lateral view along the rib margin,
along the cranial edge of the stomach. - The stomach is empty.
- The SI has some gas in it, some of it almost
looks String of Pearls. - A large amount of intra-abdominal fat is present.
- Note the large amount of sternal fat around the
heart. - RD
- Gall stones

- Surgical removal
2511 yr old MC West Highland TerrierSam

2711 yr old MC West Highland TerrierSam
- RF

rounded. - The head and tail of the spleen are visible and
enlarged. - In the VD view an ovoid structure of soft tissue
opacity is seen at the cranial margin of the left
kidney and superimposed with the stomach. - The urinary bladder is small but visible in the
caudal abdominal cavity. - RD
- Generalized hepatomegaly
- Generalized splenomegaly
- Mass in left cranial abdominal quadrant (either
enlarged left adrenal or lymph node) - Next

- RF
- The liver is small.
- Faint areas of mineralization are seen associated
with the renal pelvis. - The urinary bladder is distended.
- The contrast that enters the splenic vein
proceeds to a venous structure that appears to be
somewhat tortuous. - Also, there is reflux of some contrast material
into the splenic parenchyma. - Contrast extends through a vessel which connects
the splenic vein directly to the caudal vena cava
at the level of T13. - Contrast is also visible in the cardiovascular
structures and urinary system and it outlines
multiple small calculi. - RD
- Portosystemic shunt
