Findings
Orthogonal radiographs of the abdomen are available for interpretation.
Overall the abdomen appears to be distended, there is marked loss of serosal detail throughout the peritoneal cavity. In the right cranial abdomen the small intestines and colon are displaced caudally and towards the right side. The silhouette of the right kidney is not visible. The left kidney is within normal limits.
In the caudal aspect of the thorax, most noted on the left lateral there is a mild amount of fluid in the ventral aspect of the thorax with presence of pleural fissure lines and mild rounding of the dorso-caudal margins of the lungs
There is narrowing of the L7-S1 intervertebral disc space with sclerosis of the corresponding endplates and ventral spondylosis deformans. The T11-T12 intervertebral disc space is also narrowed. There is osseous remodeling of both coxofemoral joints.
Diagnosis
Mass effect in the cranial abdomen, which could originate from the right kidney, pancreas or splenic tail. A neoplastic etiology is considered most likely.
Decreased abdominal serosal detail, consistent with abdominal effusion and or carcinomatosis. Given the presence of a mass effect, neoplastic effusion or hemorrhage should be considered.
Scant amount of pleural effusion. Consider benign vs. neoplastic effusion based on the abdominal findings.
Bilateral coxofemoral DJD and T11-T12 and L7-S1 intervertebral disc disease.
Ultrasound
Peritoneal cavity: A large amount of echogenic free abdominal fluid is seen within the abdominal cavity. There are numerous hypoechoic mesenteric lymph nodes measuring up to 0.5 cm. Additionally, small hypoechoic nodules are visible within the markedly hyperechoic, somewhat nodular mesentery measuring up to 0.3 cm.
Urinary tract: There is a large, heterogeneous mass arising from the cranial pole of the right kidney which results in marked distortion of the right renal architecture. This mass extends medially, wrapping around the cranial mesenteric and celiac artery and aorta towards the left side. Additionally, this mass extends ventrally and causes displacement and compression of the portal vein which itself displays a turbulent blood flow. Numerous focal areas of mineralization are associated with that mass. The left kidney measures 4.0 cm findings and displays a mildly decreased corticomedullary definition. The urinary bladder contains a small amount of echogenic, suspended debris.
