Plain-English summary
A 14-year-old male Poodle was brought in with an abdominal mass and symptoms like high blood pressure, increased thirst, and hair loss. Tests revealed he had a tumor on his adrenal gland (pheochromocytoma) and was also dealing with atypical Cushing's syndrome and diabetes. The vet treated him with medications including trilostane, phenoxybenzamine, and insulin, which helped lower his blood sugar and blood pressure. After 10 months, his liver enzymes improved, and he showed no worsening of his condition, indicating that the treatment was effective.

Abstract
BACKGROUND: Pheochromocytoma (PCC) has poor prognosis and adrenalectomy is hard to be performed, in case of caudal vena cava invasion. The long-term administration of phenoxybenzamine in PCC has not been reported in dogs. CASE PRESENTATION: A 14-year-old castrated male Poodle dog presented with an abdominal mass. On physical examination, hypertension, increased lens opacity, calcinosis cutis, generalized alopecia, and systolic murmur were observed. Serum chemistry and urinalysis profiles revealed hyperglycemia, hypercholesterolemia, elevated liver enzymes, and glucosuria. Abdominal ultrasonography showed a right adrenal mass with invasion of the caudal vena cava, which was cytologically diagnosed as suspected PCC. An adrenal mass (width × height × length, 28 × 26 × 48 mm) was found on computed tomography and diagnosed as PCC with increased plasma metanephrines and normetanephrines. An adrenocorticotropin hormone stimulation test showed elevated adrenal hormones (androstenedione, estradiol, progesterone, and 17-OH progesterone) with normal cortisol, compatible with atypical Cushing's syndrome. The dog was managed with trilostane, phenoxybenzamine, and insulin therapy. Glycosylated hemoglobin and fructosamine levels gradually decreased, and hypertension resolved. In the 10-month follow-up period, the liver enzymes levels gradually decreased, and the clinical signs of the dog were well-controlled without deterioration. CONCLUSIONS: This case report describes long-term medical management without adrenalectomy of PCC complicated with atypical Cushing's syndrome and DM.
