CANINE GASTRIC NEOPLASIA - UTILITY OF ULTRASONOGRAPHY IN DIAGNOSIS

The utility of ultrasonography in the diagnosis of canine gastric neop lasia was evaluated prospectively in a series of six cases subsequentl y confirmed as having adenocarcinoma by cytological or histological ex amination or both. Gastric neoplasia was associated with mural thicken ing with loss of normal wall sonographic layers and decreased or absen t local motility. Sonographic findings were consistent with tumor loca lization obtained by other diagnostic methods employed. Ultrasonograph ic-guided, percutaneous, fine-needle aspiration biopsies were successf ul in two of She three cases in which they were performed. Ultrasonogr aphy appears useful in the diagnosis of canine gastric neoplasia.
