A 10-year-old NM Labrador cross was presented for inappetence, abdominal pain, heavy breathing, and intermittent abdominal distension. Blood work was normal. Survey radiographs showed splenomegaly and decreased liver size.
A 10-year-old NM Labrador cross was presented for inappetence, abdominal pain, heavy breathing, and intermittent abdominal distension. Blood work was normal. Survey radiographs showed splenomegaly and decreased liver size.
The left adrenal gland presented an irregular mass with phrenic vein invasion. The mass measured approximately 4.0 cm. The mass was significantly vascular. The left adrenal mass invaded the phrenic vein for approximately 2.0 cm. The right adrenal gland was uniformly enlarged and measured 3.0 x 2.0 cm with loss of corticomedullary definition.
The liver images from right and left intercostal as well as subcostal views revealed subjectively normal liver size, contour, and structure. Some age-related parenchymal remodeling was noted but likely not clinically significant at this time. Vascular and biliary tracts were of normal volume and no evidence of congestion was noted. The gallbladder revealed a minor amount of excessive debris with an echogenic wall.
Recommend serial blood pressure measurements in this patient. This is strongly consistent with pheochromocytoma with a potential for adenocarcinoma. Hyperplasia of the right adrenal gland is most likely. There was no evidence of invasion from the right. Surgical consultation is recommended.
Spleen – neoplasia, splenitis, torsion, hypersplenism
Abdomen – neoplasia, peritonitis, gastro-intestinal motility disorder
