Findings
Abdomen - ventrodorsal and opposite oblique radiographs are available for review.
Abdominal serosal margin detail is normal. Large, homogenously fluid/soft tissue opaque tubular structures extend from the pelvic inlet along the dorsal and cranial margin of the urinary bladder in the mid to caudal abdomen. On the ventrodorsal projection, the tubular structures are laterally positioned with cranial and axial displacement of the intestinal tract. The gastrointestinal tract is otherwise normal. The ventral and caudal margin of the liver is undulating with multiple rounded convexities. The liver is generally mildly enlarged, extending beyond the costal arch. The spleen, visible margins of the kidneys, and urinary bladder are normal. Ventral to the L6 vertebra, there is an ill-defined, ovoid structure (3 x 2.3cm; LxH). The mammillae are prominent.
Diagnosis
- Marked uteromegaly. Considerations include pyometra, and less likely mucometra, hydrometra, or early pregnancy. - Lobular liver margin. Hepatic nodules/masses are possible. Consider benign or malignant etiologies such as nodular hyperplasia, extramedullary hematopoiesis, metastasis or primary hepatic neoplasia. An enlarged gallbladder could also account for a ventral bulge in the liver margin. Generalized enlargement could represent metabolic hepatopathy or infiltrative/metastatic neoplasia. - Sublumbar lymphadenopathy. Reactive and metastatic etiologies are possible.
Notes
The cases was initially seen by Dr Griffith.
