6 images
Findings
Abdominal serosal detail is normal.
There is a large, well marginated, rounded, mildly lobular, soft tissue opaque mass-effect within the caudal abdomen the causes compression and ventral deviation of the colon ventrally and cranioventral compression of the urinary bladder. On the ventrodorsal image, the urinary bladder is not definitively identified due to summation with the caudal abdominal mass-effect and the descending colon is deviated to the right.
The stomach contains a mild volume of gas. The small intestine is normal in size and is contains both soft tissue material and gas. The colon contains a mild to moderate amount of gas and a mild amount of heterogeneous fecal material. The liver, spleen and kidneys are normal.
Diagnosis
- The caudal abdominal soft tissue mass effect is most concerning for metastatic sublumbar lymphadenomegaly especially given the reported left anal gland mass.
