A 14-year-old NM Welsh Terrier was presented for evaluation of abdominal distention and PU/PD. Serum biochemistry showed elevated liver enzyme activity (ALP 637, ALT 171). Low-dose-dexamethasone suppression test was within reference range. Blood pressure showed hypertension – 185-190.
Left adrenal gland nodule with capsular expansion and heterogenous parenchymal changes. Suspect pheochromocytoma given the persistent hypertension. Anti hypertensive therapy is recommend with ace inhibitors +/- Amlodipine.
The right adrenal gland was uniform with slight heterogenous parenchymal changes at 2.0 x 1.16 cm at the cranial pole and 0.63 cm at the caudal pole. The left adrenal gland revealed a nodule at the caudal pole that measured 1.6 cm with capsular expansion and heterogenous parenchymal changes. This is consistent with adenoma or possible adenocarcinoma that is non functional or pheochromocytoma. Ultrasound-guided FNA were performed without complication.
None
No images of the right adrenal were available.
Adrenal – pheochromocytoma, non-functional neoplasia
Essential hypertension
Liver – nodular regeneration, reactive hepatopathy, vacuolar hepatopathy, neoplasia
