Abstract
BackgroundThis case report describes the clinical and ultrasonographic findings in a Swiss Braunvieh cow with lymphosarcoma of the abomasum.Case PresentationThe main clinical findings were vomiting in response to eating and melena. The results of serum biochemistry and rumen fluid analysis were indicative of abomasal reflux syndrome. The main ultrasonographic findings were two enlarged lymph nodes caudal to the reticulum and a severely enlarged abomasum with thickening of the abomasal wall and folds. Based on all the findings, pyloric stenosis caused by lymphosarcoma was tentatively diagnosed and later confirmed at postmortem examination.ConclusionsThis is an interesting case, which broadens the spectrum of abomasal reflux syndrome.

This is an interesting case, which broadens the spectrum of abomasal reflux syndrome
Lymphosarcoma causes thickening of the abomasal wall, which leads to progressive impairment of passage of ingesta, ulcers, haemorrhage, melena, anaemia and occasionally abomasal reflux and hypochloraemic alkalosis [2]
Summary
This case report describes the clinical and ultrasonographic findings in a Swiss Braunvieh cow with lymphosarcoma of the abomasum.Case Presentation: The main clinical findings were vomiting in response to eating and melena. Diagnosis of abomasal lymphosarcoma may be difficult when peripheral lymphadenopathy is absent; this occurred in 46% of 112 cases described [3]. Lymphoblasts in a peripheral blood smear are indicative of lymphosarcoma but are seen in only approximately 10% of cases [3]. In a recent case presented to our hospital because of melena, round to oval structures were seen via ultrasonography caudal to but not in direct contact with the reticulum.
