Sonographic Assessment of the Normal and Abnormal Feline Mammary Glands and Axillary and Inguinal Lymph Nodes

Figure 3

B-mode ultrasound of lymph nodes in a two-year-old cat with abnormal mammary glands and a three-year-old cat with normal mammary glands. (a) Right superficial inguinal lymph node (between the markers) of rounded shape and heterogeneous echotexture, without the central hyperechogenic line. (b) Left superficial inguinal lymph node (between markers) with oval shape, hypoechoic parenchyma, and homogeneous echotexture, with the central hyperechogenic line. (c) Right axillary lymph node (between markers) with elongated oval aspect, homogeneous echotexture, and hypoechoic parenchyma, without central hyperechogenic line. Cr: cranial. Frequency = 15 MHz.
