Plain-English summary
A 15-year-old domestic shorthair cat was brought in with symptoms like weakness, increased thirst and urination, and gastrointestinal issues. The vet found a mass on the left adrenal gland and a blood clot in the nearby renal vein. The cat underwent surgery to remove the adrenal tumor and the clot, but the kidney was saved. Remarkably, 30 months later, the cat showed no signs of illness and was doing well.

Abstract
A 15-year-old domestic shorthair cat was presented with gastrointestinal signs, polyuria, polydipsia, and weakness. Abdominal bruit ("whooshing" sound from turbulent blood flow) and hypertension (systolic blood pressure: 200 mmHg) were present. A left adrenal gland mass was detected with abdominal ultrasonography; a subsequent CT examination identified a mass and a thrombus in the ipsilateral renal vein. Adrenalectomy and venotomy were completed but nephrectomy was not necessary. Histological diagnosis was an adrenocortical carcinoma. There were no clinical signs at a follow-up examination 30 mo after surgery. Key clinical message: This report describes successful surgical management of feline adrenocortical carcinoma with renal vein invasion without kidney damage. This case suggests that, after correct diagnosis and in well-selected cases, surgery to remove adrenal tumors and thrombi in cats, despite renal vein invasion, can be done with excellent short- and long-term outcomes.
