A Spigelian hernia is a rare type of abdominal wall hernia that develops below the naval, more often on the right side of the abdomen. Spigelian hernias can be difficult to diagnose. Symptoms can vary and depend on the size of the hernia and contents within the hernia sac.
A spigelian hernia protrudes through a weakness between the muscle fibres of the abdominal wall. This protrusion may contain a section of the intestines but in other cases it takes the form of an empty sac.
