Plain-English summary

An 11-year-old female Labrador was brought in for an abdominal ultrasound due to liver disease, which revealed a swelling on her left adrenal gland. Although the vet suspected a hormone-related issue, tests showed no signs of hyperadrenocorticism (Cushing's disease). At the owner's request, the vet performed surgery to remove the adrenal gland, and the mass was found to be a benign tumor made up of fat and blood cells. After the surgery, the dog was diagnosed with adrenal myelolipoma, and the procedure likely helped improve her health.

Abstract

Abdominal ultrasound examination in an 11-year-old, intact, female Labrador dog with hepatic disease revealed a nodular swelling of the left adrenal gland. Hyperadrenocorticism was suspected, but endocrine tests were negative. At the owner's request, an adrenalectomy was performed. Grossly, a nodular mass protruded from the external surface of the left adrenal gland and in cut section was hemorrhagic and effaced the cortical and medullary regions. Histologic examination revealed a cortical neoplasm with medullary involvement. The mass was composed of well-differentiated adipose cells, megakaryocytes, hematopoietic cells, and macrophages containing hemosiderin deposits. A diagnosis of cortical adrenal myelolipoma was made.
