Adenoma hepatocelular- relato De caso

Abstract

Hepatocellular adenoma is an uncommon benign liver neoplasm in dogs, especially in geriatric patients, characterized by slow growth and nonspecific clinical signs, which may delay diagnosis. This study reports the case of an 11-year-old male Beagle dog submitted to partial hepatectomy for removal of a hepatic mass. The patient presented clinical signs such as vomiting, diarrhea, prostration, and abdominal pain, and underwent laboratory and imaging examinations, including ultrasound and computed tomography. Imaging findings revealed an expansive hepatic lesion without vascular invasion. Surgical treatment was performed using the guillotine technique associated with a linear stapler and Miller’s knot, ensuring effective hemostasis. The multimodal anesthetic protocol proved to be safe and effective for the geriatric patient. Histopathological examination confirmed the diagnosis of hepatocellular adenoma, demonstrating a favorable prognosis and absence of metastasis. It is concluded that the association of early diagnosis, adequate surgical planning, advanced hemostatic techniques, and intensive postoperative monitoring is essential for therapeutic success in benign hepatic neoplasms in dogs.
