Background: Adrenal incidentalomas are masses accidentally discovered during imaging examinations performed whenthere is no suspicion of adrenal disease. Even with a low prevalence, it is important to perform a reliable evaluation observing biological behavior and determining whether the hormonal activity is stimulated. Frequently, these masses are notfunctional, but in some cases, there is increased cortisol activity, and patients with adrenal incidentalomas may presenthyperadrenocorticism. This report aims to describe the clinical, tomographic, and histopathological aspects of a case ofadrenal incidentaloma detected in a routine abdominal ultrasound.Case: An 8-year-old, male, maltese dog with occasional emesis, halitosis, claudication of the left pelvic limb, and previous compensated and untreated cardiomyopathy was treated at the Veterinary Hospital of the Federal University of MatoGrosso (HOVET-UFMT). Physical examination revealed arterial hypertension and claudication, with the positive posteriordrawer test suggesting rupture of the cruciate ligament. The blood count showed no alteration, and the serum biochemistryrevealed a slight increase in the activity of alanine aminotransferase. In order to investigate this increase, an abdominalultrasound was performed. Slight hepatomegaly and a heterogeneous mass of irregular edges were observed with a moderate and difficult-to-delimit vascularization of the adrenal gland. Left knee radiography raised the suspicion of rupture ofthe cranial cruciate ligament due to the cranial displacement of the tibia in relation to the femur. Computed tomographywas performed to define the extent and delimitation of the mass, which was compatible with a tumor of the right adrenalgland characterized by the visualization of an abdominal mass...
