Findings

Orthogonal radiographs of the whole body are available for interpretation.

Overall there is decreased serosal detail in the caudo-ventral abdomen. Dorsal to the urinary bladder and ventral to the colon, there is a tubular well defined soft tissue opaque structure extending from the pelvic inlet cranially. In the cranial abdomen just caudal to the liver on the right side there is a small amount of mineralized conglomerate between the 10th and 11th rib.

There is mild to moderate diffuse mammary enlargement.

The thorax is considered to be within normal limits. There is no radiographic evidence indicative of pulmonary metastasis.

Diagnosis

Uterine enlargement. Diagnostic differential include uterine adenocarcinoma, vs. pyometra vs. less likely pregnancy.

Mineralization in the right cranial abdomen could be consistent with cholelithiasis. Alternatively fat necrosis could be considered.

Pathology Report

Uterine enlargement confirmed to be uterine adenocarcinoma.

Uterine adenocarcinoma is the most common neoplasia seen in female rabbits and in some breeds can reach an incidence of 80% in does > 4 years of age. ( Weisbroth SH. Neoplastic diseases.
