Ultrasonographic findings in a cow with abomasal lymphosarcoma: case report.

Braun U, Schnetzler C, Dettwiler M, Sydler T, Meyer S, Gerspach C - BMC Vet. Res. (2011)

Bottom Line: 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.This is an interesting case, which broadens the spectrum of abomasal reflux syndrome.

ABSTRACT

Background: 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. 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.

Conclusions: This is an interesting case, which broadens the spectrum of abomasal reflux syndrome.

Ultrasonogram of the enlarged pylorus. Ultrasonogram of the enlarged pylorus in a Swiss Braunvieh cow with lymphosarcoma of the abomasum. The pylorus contains ingesta and the thickness of its wall is increased. The image was obtained from the cranial right flank at the level of the costochondral junction using a 5.0-MHz convex transducer. 1 Lateral abdominal wall, 2 Thickened wall of pylorus, 3 Ingesta in pylorus, Ds Dorsal, Vt Ventral.

Figure 2: Ultrasonogram of the enlarged pylorus. Ultrasonogram of the enlarged pylorus in a Swiss Braunvieh cow with lymphosarcoma of the abomasum. The pylorus contains ingesta and the thickness of its wall is increased. The image was obtained from the cranial right flank at the level of the costochondral junction using a 5.0-MHz convex transducer. 1 Lateral abdominal wall, 2 Thickened wall of pylorus, 3 Ingesta in pylorus, Ds Dorsal, Vt Ventral.

Mentions: Endoscopic examination of the oesophagus and radiographic examination of the reticulum revealed no abnormal findings. Ultrasonographic examination of the reticulum (LOGIQ 7, GE Healthcare) using a 5.0 MHz convex transducer with a penetration depth of 10 cm showed reticular hypermotility with five normal biphasic contractions per 3 minutes (normal 3 to 4 contractions) [4]. Two large oval heterogeneous structures measuring 4.5 × 5.2 cm were seen caudal to the reticulum and were thought to be lymph nodes (Figure 1). Scanning of the right side revealed that the abomasum extended to the cranial flank because of severe dilatation. The abomasal contents were hypoechogenic and the wall and folds of the abomasum were thicker than normal. The pylorus was seen in the cranial flank region at the level of the costochondral junction (Figure 2). It was positioned horizontally and was increased in size with a diameter of 10 cm.
