From Chapter 15 - Abdominal Cavity, Lymph Nodes, and Great Vessels 
Figure 15.3 Cysterna chyli in a 10 year old Labrador dog with gastroenteritis. There was no peritoneal effusion or other signs of lymphatic congestion. The cysterna (arrowheads) appears as a well-defined cystic structure partly encircling the mid abdominal aorta on its dorsal left border. It appears fusiform in longitudinal plane (A) and oval to semicircular in transverse plane (B). co-authored by Marc-André d'Anjou and Éric Norman Carmel
