Plain-English summary
An 8-year-old male domestic shorthair cat was brought to the vet after losing weight over four months, despite having a normal appetite. The cat also showed signs of increased thirst and urination, weakness, and high blood pressure. After imaging tests revealed a mass on the left adrenal gland, the vet performed surgery to remove it. The tumor was confirmed to be a pheochromocytoma, a rare type of adrenal tumor. Following the surgery, the cat's condition improved, and he was monitored for recovery.

Abstract
Pheochromocytoma in cats is a rare clinical condition characterised by the development of a secretory endocrine tumour that arises from the adrenal medulla. An 8-year-old castrated male, domestic shorthair cat was referred for further investigation of a 4-month history of progressive weight loss with normal appetite, polyuria/polydipsia, generalised weakness, and severe hypertension. Sonography and computed tomography of the abdomen disclosed a mass arising from the left adrenal gland. The contralateral adrenal gland was normal in size and shape. Results from a low dose dexamethasone suppression test and measurements of plasma aldosterone concentration and plasma renin activity ruled out a cortisol-secreting tumour and aldosteronoma. The clinical presentation made a sex-steroid secreting tumour unlikely. Increased plasma metanephrine and normetanephrine concentrations prioritised the differential diagnosis of pheochromocytoma. The cat underwent adrenalectomy of the left gland and histopathological diagnosis with immunohistochemical markers confirmed the diagnosis.
