Ultrasonographic biometry of medial iliac and jejunal lymph nodes in apparently healthy dogs

The present study was conducted on 30 apparently healthy dogs of either sex. The aim was to describe ultrasonographic features of medial iliac lymph nodes (MILN) and jejunal lymph nodes (JJLN) in all the dogs. MILN and JJLN were evaluated, ultrasonographically for location, length, height, shape, echotexture, echogenicity and ease of scanning. Majority of these lymph nodes were easy to scan, had homogenous echotexture and were isoechoic or hypoechoic to the surrounding tissues. The dogs were grouped according to the breed, age and body weight. Body condition score (BCS) was assigned. The means of the dimensions of these lymph nodes were compared in different age groups and body weight groups. Positive correlation could only be seen between the length of lymph nodes and the body weight of the dogs. The breed, BCS, age and gender had no effect on the biometric measurements of these small structures. Weak correlations were found between dimensions of the lymph nodes with height of aorta and mean renal cortical thickness.
