Fig. 1A —Extent of hernia sac was evaluated visually based on relationship
between hernia sac and pubic tubercle on axial CT images. Extended sac
(arrow) extends medial to pubic tubercle (arrowhead) in
72-year-old man.

Fig. 2 —Compression of femoral vein on CT scans through acetabula and
pubic symphysis in 66-year-old woman. Each lower image is magnification of
upper portion on each side. Right femoral vein is elliptic, and hernia sac
(arrowhead) lies in direction of minor diameter of right femoral vein
(solid white line). Minor diameter of right femoral vein (a) is less
than two thirds of diameter of femoral vein (b) in symmetric direction
(dotted white line).
