Ultrasonography of Osteosarcoma in Dogs
Sonography Atlas of Dogs

Esophageal mass in a 14-year-old Welsh Corgi. A and B: Thoracic radiographs reveal a homogeneous, soft-tissue opacity (M, arrows) associated with the caudal mediastinum, in the caudal region of the esophagus (E), silhouetting with the diaphragm. The position of the ultrasound transducer is shown in B. C and D: Ultrasonographic and enhanced labeled images obtained with a ventral transhepatic approach (sagittal plane). At the level of the esophageal hiatus, the mass (M, arrows) is associated with the esophagus (E). Liver and stomach (S) are visible in the near field, and the lung-diaphragm interface (D) manifests as a curvilinear, strongly hyperechoic structure bordering the esophageal mass.

Mucosal hyperechoic striations.  Longitudinal (A) and transverse (B) sonograms of thickened jejunal segments with hyperechoic linear striations within the mucosal layer of a 5 year old French Bulldog. The striations represent dilated lacteals. This dog had a long history of inflammatory bowel disease. Peritoneal effusion is present (*).  C and D: Similar but more severe findings are present in this 9 year old Jack Russell terrier presented with protein losing enteropathy.  Note the thickened and hyperechoic adjacent fat (F), often present in these cases.

Ultrasonography of a pylorogastric intussusception in case 1. (A) A mass (m), 38 × 31 mm in size, connected with the descending duodenum (d). The mass occupied the body of the stomach (s). (B) Concentric multiple rings (arrow heads) represent an intussusception. The pyloric wall (double-headed arrow and W) is thickened (7.1 mm) with indistinct layering. Short arrows are multiple hypoechoic regions in the pyloric wall. Note the edematous change of mesentery (o).

 Ultrasonography a pylorogastric intussusception in case 2. (A) In the transverse view, a concentric, multiple ring (arrow) and edematous mesentery (o) was observed in the gastric body. (B) In longitudinal image of the ring, the invaginated pylorus showed thickened muscular layer (^*) with distinct layering. The stomach (s) was dilated with fluid.

Intestinal vascular anomaly in a 9 month old Labrador dog with vomiting and diarrhea.

A and B: Transverse sonograms of one fluid filled colonic segment with a thickened, nodular-like wall made of intramural enlarged varices (arrows in A), as confirmed using color flow Doppler (in B). A large network of numerous anomalous small vessels was seen throughout the abdomen, especially in the mesentery and near the main portal vein. C: Transverse post-contrast CT image of the caudal abdomen showing the intramural colonic vessels (arrow). D: Reconstructed CT dorsal image illustrating the numerous anomalous enlarged and tortuous vessels supportive of portal hypertension and acquired portosystemic shunts. Note the intramural colonic vessels (arrows). The left side of the liver is nearly absent. Because of the guarded prognosis, the dog was euthanatized and the final diagnosis is arteriovenous malformation with marked arteriolar proliferation and hypertrophy, venous ectasia, lobular atrophy and fibrosis.

Ultrasonographic images in the sagittal orientation of the umbilical region (A) and left lumbar (B and C) showing free abdominal air (arrows) that led to increased echogenicity and thickening of the peritoneal stripe with reverberation artifacts. Free abdominal air was present along the ventral peritoneum adjacent to the spleen and small intestine. Intraluminal air was also observed in the intestinal lumen (arrowhead) and associated with “dirty” acoustic shadowing.
