Spigelian hernia, a little-known cause of abdominal pain

Spiegelian hernia is a rare cause of abdominal pain in the childhood. It occurs along the semilunar line, in the transitional zone of the aponeurosis and the transverse muscle of the abdomen. It presents an atypical clinic and its low incidence in pediatrics can lead to errors or diagnostic delays with the consequent risk of complications.
