Radiographic Impressions:
Differentials for the mass effect in the caudal abdomen should include
sublumbar lymphadenopathy secondary to metastatic neoplasia, and less likely infectious
disease, abscess, or hematoma.
Ultrasonographic Impressions:
Origin of the mass may be lymph node, musculature, vascular or
neural. Differentials would include neoplasia and infectious disease
(granulomatous). A fine needle aspirate was obtained with no periprocedural
complications.
