Ipsilateral Spigelian hernia: just an infrequent variant?

Abstract

Spigelian hernias are generally considered to occur through solitary defects in the fascial layers of the anterior abdominal wall in the ‘Spigelian hernia belt’ but can be found anywhere along the line of the linea semilunaris. They are uncommon in children and in adults thought to be acquired and associated with obesity. We describe an unusual case of Spigelian herniation previously unreported and possibly previously unrecognised.
