Case Study
Adrenal mass in an 11 year old mixed breed dog with weight loss and hypertension
Sonographic Differential Diagnosis
Left adrenal gland mass with concurrent liver mass. Suspect pheochromocytoma given the invasive nature of the mass and concurrent severe systemic hypertension. Hepatic metastasis is likely.
Image Interpretation
A complex mass arising from the left adrenal gland (4.71 x 1.67 cm) was present invading and expanding the vena cava. Multiple masses are noted in the liver of similar echogenicity to the adrenal mass. Loss of structural detail is significant.
DX
Suspect pheochromocytoma with hepatic metastasis.
Outcome
The patient was euthanized.
Comments
Multiple studies have shown that invasive adrenal masses are either pheochromocytoma or adenocarcinoma. Adenocarcinoma may functional or nonfunctional. Technically, this could have been a non-functional carcinoma, but this diagnosis would not explain the severe systemic hypertension present in this patient. Therefore, pheochromocytoma was strongly suspected. Unfortunately, no necropsy or post mortem biopsy was permitted by the owner.
Clinical Differential Diagnosis
Gastritis, neoplasia, pancreatitis, foreign body, starvation.
Sampling
None.
