Achados ultrassonográficos de linfoma alimentar com metástase para adrenal em felino - relato de caso

Abstract

Lymphoma is a neoplasm that affects the gastrointestinal tract and regional lymph nodes, normally affecting the small intestine and sometimes the liver, spleen, oral cavity, esophagus and pancreas. It commonly occurs in middle-aged and senile cats, over 10 years of age, with no apparent sexual predisposition. Abdominal ultrasonography is a valuable tool when suspected food lymphoma, as it allows an assessment of the gastroinstestinal tract, evaluating the thickness and stratification of the intestinal wall, in addition to assessing lymph nodes and other abdominal organs. The objective of the report was to describe the findings of this ultrasound in the detection of metastasis of food lymphoma in a feline's adrenal gland. On ultrasound examination, a small intestine of the jejunum was observed, severe focal thickening (0.99 cm) of the intestinal wall with loss of stratification of layers and the left adrenal appeared as a single, hypoechogenic and heterogeneous mass, well delimited, with irregular contours, measuring about 4.8 cm x 2.25 cm. After histopathology, the diagnosis of food lymphoma with a primary focus on the small intestine with metastasis to the left adrenal was confirmed.
