Sonographic Differential Diagnosis

Gastric mural mass compatible with neoplasia.(Lymphoma, round cell tumor such as mast cell) .

Image Interpretation

This cross-sectional image at the gastric fundus reveals marked focal mural thickening with complete loss of wall layering. The gastric wall thickening is adjacent to the liver and in the near field, supporting lesser curvature involvement. The fragmented linear echogenicity noted within the mid aspect of the mass represents a 22 gauge needle.

DX

Lymphoblastic lymphoma

Outcome

The patient initially responded well to a CHOP chemotherapy protocol. However, the owner elected humane euthanasia 10 weeks post diagnosis due to lack of response to therapy.
