Sonographic Differential Diagnosis

Gastric wall mass consistent with neoplasia such as lymphosarcoma, similar round cell tumor, leiomyosarcoma less likely. Severe inflammatory or granulomatous gastritis is considered much less likely

Image Interpretation

Severe, circumferential gastric wall thickening is present. The affected gastric wall is hypoechoic and lacks discernible wall layering. The linear echogenicity noted at the one o`clock position is a 22 gauge needle sonographically guided for aspiration. The video demonstrates the concentric nature of the hypoechoic infiltrative pattern rendering this lesion non resectable.

DX

Gastric lymphoma

Outcome

The patient was euthanized due to lack of response to chemotherapy.

Clinical Differential Diagnosis

GI pathology – Intestinal neoplasia, gastric neoplasia, IBD with lymphadenopathy, foreign body, sequestrum, granulomatous disease; pancreatic pathology – pancreatitis
