Achados de imagem no adenocarcinoma intestinal em felino

Abstract

Intestinal adenocarcinoma is the second most common type of malignant neoplasm to affect the intestinal tract of felines, second only to lymphoma, being highly invasive locally and causing nonspecific clinical signs. Ultrasonography is an important tool in the evaluation of felines with gastrointestinal clinical signs, being a simple, non-invasive, low-cost and widely available exam that allows the evaluation of intestinal stratification, thickness and motility, in addition to evaluating the other abdominal organs for investigation of metastases. Adenocarcinoma typically affects a single segment or area causing thickening and loss of definition of the intestinal stratification, in addition to occasionally causing mechanical ileus. The definitive diagnosis is obtained through biopsy and histopathological examination of the segment and the recommended treatment is surgical extirpation of the affected segment with a safety margin. This study aims to report the diagnosis and follow-up of a feline with intestinal adenocarcinoma, which required several radiographic and ultrasound examinations and successive surgical interventions, including three enterectomies, allowing adequate stabilization of the patient who is without clinical complaints after 8 months of the last intervention.
