The anterolateral abdominal wall is a layered structure composed of skin, fascia, muscles, extraperitoneal fat, and peritoneum that extends from the thorax to the pelvis and bounds the abdominal cavity and its associated organs.[1] It plays an important role in the torso's movement, the spine's stabilization, retention of a physical barrier, and increase and maintenance of intra-abdominal pressure.[2][3] Numerous nerves traverse the anterolateral abdominal wall to serve regions of the abdominal wall, pelvis, and perineum. A variety of pathologies have the potential to impact the anterolateral abdominal wall nerves, including trauma, neoplasm, and infection. Any clinical involvement of these nerves may result in pain, loss of sensation, or motor deficits and reduce an individual's quality of life.
