The medial iliac and superficial inguinal lymph nodes are not routinely palpable in the dog, and ultrasound imaging provides an alternate noninvasive technique to assess these lymph nodes, as well as to guide needle aspiration. Herein we describe the ultrasound characteristics of the medial iliac and superficial inguinal lymph nodes in 50 healthy dogs, as well as frequency and ease of node detection. The relationship between the size of the lymph nodes and the following variables was assessed: age, gender, body weight, body condition score, body length, and thoracic height and width. Right and left medial iliac lymph nodes were detected in 50 (100%) dogs, right superficial inguinal lymph node(s) in 49 (98%) dogs, and left superficial inguinal lymph node(s) in 47 (96%) dogs. In > 90% of both sets of lymph nodes, the echogenicity was hypoechoic or isoechoic to surrounding tissues, with a corticomedullary or homogenous echotexture, smooth, clearly defined margins, and a fusiform shape. Increasing weight, distance from the sternal manubrium to the ischium, and thoracic height and width were associated with increased lymph node size (P-values < 0.05). Average lymph node sizes and range of sizes provide preliminary reference values for the medial iliac and superficial inguinal lymph nodes in normal dogs.
在犬类中，通常无法摸到髂内侧淋巴结和腹股沟浅淋巴结，超声成像提供了一种替代的非侵入性技术来评估这些淋巴结，并指导针吸活检。在此，我们描述了50只健康犬的髂内侧淋巴结和腹股沟浅淋巴结的超声特征，以及淋巴结检测的频率和难易程度。评估了淋巴结大小与以下变量之间的关系：年龄、性别、体重、身体状况评分、体长以及胸高和胸宽。50只（100%）犬检测到左右髂内侧淋巴结，49只（98%）犬检测到右侧腹股沟浅淋巴结，47只（96%）犬检测到左侧腹股沟浅淋巴结。在两组淋巴结中，超过90%的淋巴结回声低于或等于周围组织，具有皮质髓质或均匀的回声纹理，边缘光滑、清晰，呈梭形。体重增加、从胸骨柄到坐骨的距离增加以及胸高和胸宽增加与淋巴结大小增加相关（P值<0.05）。平均淋巴结大小和大小范围为正常犬的髂内侧淋巴结和腹股沟浅淋巴结提供了初步参考值。
