(Top) Transverse extended FOV, grayscale ultrasound shows the relationship of the medially located rectus abdominis and the laterally
located oblique and transverse abdominal muscles. Medially the external and internal oblique and the transversus abdominal muscles
form aponeuroses that comprise the rectus sheath, with the muscles thinning at the linea semilunaris. The linea alba is thin in the lower
abdomen. (Middle) Transverse grayscale ultrasound at the right anterolateral abdominal wall shows the relationship of the lateral
abdominal wall muscles in better detail. Note the oblique and transverse abdominal muscles taper medially as they become
aponeuroses. (Bottom) Correlative, axial contrast-enhanced CT illustrates the muscles of the abdominal wall. The rectus abdominis
muscle in the anterior abdominal wall,and the oblique and transverse abdominal muscles in the anterolateral abdominal wall and their
aponeuroses are shown.
