Case Study

07_00183 Oryoal P Adrenal mass

A 15-year-old SF DSH was presented for evaluation of walking hunched in the back legs, PuPd, and decreased appetite. On physical examination, dental disease, mild heart murmur, and a mass in her mammary chain were present. Urinalysis showed specific gravity of 1.019 and proteinuria. Abnormalities on blood work were mild hyperglobulinemia and hypokalemia. A cursory in-house ultrasound revealed a mass near the left kidney.

 

Sonographic Differential Diagnosis

The left adrenal gland mass appears resectable, likely carcinoma.
Given the subnormal potassium aldosterone secreting tumor is significantly suspected. Aldosterone levels are recommended as well as blood pressure measurements.

Image Interpretation

Left adrenal gland mass was noted with mixed echogenic changes measuring 2.67 x 1.92 cm. The left adrenal gland mass impinges upon the vena cava; however, no overt invasion was noted. The right adrenal gland was normal and measured 0.43 cm.
