A<unk>  (or lateral ventral hernia) is a hernia through the<unk>  fascia, which is the aponeurotic layer between the rectus abdominis muscle medially, and the semilunar line laterally. These hernias almost always develop at or below the linea arcuata, probably because of the lack of posterior rectus<unk> eath. These are generally interparietal hernias, meaning that they do not lie below the subcutaneous fat but penetrate between the muscles of the abdominal wall; therefore, there is often no notable swelling.
Most of these hernias are small, and, as such, there is a high risk of strangulation. Most of them develop around age 50 (4th-7th decade of life).  As an entity, they are rare, when compared other types of hernias.
