摘要

The aim of this study was to describe the ultrasonographic and computed tomographic findings of a rare case of an atypical lipoma located in the abdominal cavity of a 13-year-old neutered male Schnauzer weighing 10.3 kg. The animal had a history of dyslipidemia and hypothyroidism, and, due to this clinical background, additional diagnostic tests were requested. On B-mode ultrasonography, an amorphous, hyperechoic, and homogeneous structure with well-defined borders was visualized in the mid-abdominal region, measuring approximately 10.3 cm in length and 6.8 cm in height. Subsequently, interventional ultrasonography was performed to obtain a guided sample. Because of the difficulty in delineating and evaluating adjacent organs, the animal was referred for computed tomography, which identified a well-defined expansile mass with smooth margins and homogeneous density, exhibiting attenuation values consistent with adipose tissue. The integration of imaging modalities, combined with image-guided sampling, proved essential for complementing the clinical assessment and guiding the diagnostic process.
