Spigelian hernia: a rare case presentation

Spigelian hernia, a case report

“…Spigelian hernias are rare inter-parietal hernia which is also called “spontaneous lateral ventral hernia” or “hernia of semilunar line”. Sometimes it is called intraparietal, interstitial, intramuscular or intra mural hernia because it is locked between the different muscle layers of the abdominal wall [ 3 ]. The “Spigelian hernia belt” is the site where Spigelian hernia mostly occurs and it is located in a paramedian region lying 0 to 6 cm cranial to a line running between both anterior superior iliac spines [ 7 ].…”

“…The “Spigelian hernia belt” is the site where Spigelian hernia mostly occurs and it is located in a paramedian region lying 0 to 6 cm cranial to a line running between both anterior superior iliac spines [ 7 ]. The Spigelian fascia varies in width along the semilunar line and it gets wider as it approaches the umbilicus [ 3 ].…”

“…The hernia sac surrounded by extra peritoneal fatty tissue is often intra-parietal passing through transverse and internal oblique aponeurosis and spreading out behind the intact aponeurosis of external oblique [ 3 ]. The hernia sac usually contains the greater omentum but involvement of other organs has been reported, including the small intestine, colon, stomach, gallbladder, Meckel's diverticulum, appendix, ovaries and testes [ 7 ].…”

“…Most of these hernias occur in the lower abdomen where posterior sheath is deficient. The hernia ring is well defined defect in the transverse aponeurosis [ 3 ].…”

Spigelian hernia: a rare abdominal hernia

“…Spigelian hernia is named after Spighel (an anatomist from Belgium) who described semilunar line in 1645. 4 But the hernia is thought to be first described by Klinkosch in 1764. 5 Spigelian hernia is a rare ventral hernia which occurs secondary to a defect in the transversus abdominal muscle and rectus sheath aponeurosis which allows abdominal contents to protrude through the linea semilunaris (also known as spigelian line or belt).…”
