Spigelian hernia characteristically presents along which anatomical line?

• A Along the linea alba in the midline
• B At the superior lumbar triangle (Grynfeltt-Lesshaft)
• C At the femoral ring medial to the femoral vein
• D Along the semilunar line at the lateral edge of rectus abdominis ✓

Explanation

Spigelian hernia (also called lateral ventral hernia) occurs through the aponeurosis of the transversus abdominis along the semilunar line (linea semilunaris), most commonly at or below the arcuate line where the posterior rectus sheath is absent. The hernia sac passes between muscle layers, making it difficult to detect clinically. Ultrasonography or CT is often required for diagnosis. Incarceration risk is high due to the tight fascial margins.
