Extraocular muscle pareses in patients with Cushing syndrome are virtually always associated with a greatly enlarged pituitary tumor and with advancement on oculomotor nerves. The present report concerns a patient with a rapidly progressive adrenocorticotropic hormone (ACTH)-dependent hyperadrenocorticism and sudden onset of an unilateral third nerve paresis. The patient had no demonstrable pituitary tumor. After a total adrenalectomy and correction of hyperadrenocortisolism, his third nerve paresis subsided. Ocular paresis may occur in a patient with Cushing syndrome even in the absence of mechanical involvement of ocular nerves by a pituitary tumor.

Generalised paresis, severe hypokalaemia and kaliuresis, metabolic alkalosis and hypertension, characteristic of mineralocorticoid excess, were identified in a dog with hyperadrenocorticism due to a functional adrenocortical carcinoma. Aldosterone concentration was decreased and deoxycorticosterone concentration increased in the presence of hypokalaemia. These metabolic abnormalities resolved with resection of the carcinoma. Mineralocorticoid excess in dogs with hyperadrenocorticism is generally considered to be of little clinical significance but resulted in the acute presentation of this patient. The possible pathogenesis of mineralocorticoid excess in this case of canine hyperadrenocorticism is discussed.

A 14-year-old, mixed breed dog was presented with acute pain and paresis of the hindlimbs. Ultrasonography revealed an intraluminal mass and an abrupt halt of blood flow signal in the distal abdominal aorta. The mass had homogeneous hyperechoic echotexture compared with blood flow. Although clinical presentation suggested a thromboembolism and pituitary dependent hyperadrenocorticism was suspected as a predisposing cause based on adrenal function tests and ultrasonography, an aortic chondrosarcoma originating from the distal abdominal aorta was diagnosed with histologic examination. Primary aortic sarcoma is extremely rare, and extraskeletal chondrosarcoma is only reported in 2 cases previously. Aortic neoplasm should be included in differential diagnosis when an intraluminal aortic mass is observed on ultrasonography and acute paresis of hindlimbs is shown.

Adrenocortical carcinoma (ACC) co-secreting aldosterone and cortisol is extremely rare. We report the case of a 37-yearold female who presented with paresis and facial puffiness. Evaluation revealed hypertension, hyperglycemia, severe hypokalemia and hyperaldosteronemia with elevated plasma aldosterone to renin ratio (ARR). Urinary free cortisol estimation showed elevated levels. Computed tomography scan revealed a right adrenal mass. Radical adrenalectomy specimen revealed ACC (T3N1). Post-operatively, the patient became normotensive and euglycemic with normalization of urinary cortisol and ARR. This case highlights the need for a complete evaluation in patients of hyperaldosteronism if overlapping symptoms of hypercortisolism are encountered, to avoid post-operative adrenal crisis.
