A 12-year-old intact male German Shorthair Pointer was presented for evaluation of intermittent vomiting, lethargy, and decreased appetite. Serum biochemistry showed hypokalemia. A gas-filled pylorus was evident of on survey radiographs.
Case Study
04_00503 Spencer P Pyloric thickening with stricture
Sonographic Differential Diagnosis
Stricturing pyloric mass and possible chronic inflammatory epigastric lymphadenopathy. Primary differentials include pyloric carcinoma versus hypertrophic gastropathy obstructive pattern. There was no overt evidence of organ metastasis at this time. Epigastric lymph node may be metastasis.
Image Interpretation
The stomach was severely dilated with fluid accumulation. The pyloric outflow was thickened in this patient. The pyloric thickening loses detail and meets neoplastic criteria and is obstructive. Serosa to mucosa measured 1.26 cm. Regional lymphadenopathy was noted. Epigastric lymph node was enlarged.
