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.
Epigastric, umbilical, incisional, lumbar, internal, and Spigelian hernias all occur at different sites over the abdomen in areas that are prone to anatomical or structural weakness. With the exception of internal hernias (within the abdomen), these hernias are commonly recognized as a lump or swelling and are often associated with pain or discomfort at the site. Internal hernias can be extremely difficult to diagnose until the intestine (bowel) has become trapped and obstructed because there is usually no external evidence of a lump.
