Spigelian Hernias, A Diagnostic Enigma - A Case Report

چکیده
Spigelian hernias occur in the lower abdomen where the posterior sheath is deficient. It protrudes through a slit like defect in the anterior abdominal wall adjacent to the semilunar line. The hernia ring is formed as a well-defined defect in the transversus abdominis. Extraperitoneal fatty tissue surrounds the hernial sac and it passes through the transversus and the internal oblique aponeuroses. Then spreads out beneath the intact aponeurosis of the external oblique. Spigelian hernia is a rare entity and constitutes 0.12% of abdominal wall hernias. Due to its interparietal position, it is difficult to diagnose it clinically. It commonly does not cause a noticeable bulge in the abdominal wall. But in the present case a swelling was visible and the hernial content was palpable but no hernial orifice could be felt.
