Figure 1 Imaging study of an 83-year-old woman with right lateral thigh pain. A: Axial T2-weighted thigh magnetic resonance (MR) image shows the small bowel (open arrow) located between the right pectineus muscle (orange arrow) and obturator interternus muscle (green arrow); B: Coronal T2-weighted thigh MR image shows the small bowel (open arrow) herniating through the right obturator canal; C and D: Axial (C) and (D) coronal contrast-enhanced retroperitoneal computed tomography (CT) images show the right obturator hernia (open arrow) and strangulation point (yellow arrow) at the right obturator canal; E and F: Axial (E) and (F) coronal contrast-enhanced retroperitoneal CT images show a dilated loop of the small bowel upstream (arrowheads); G and H: Ultrasonographic images of the right inguinal region (G and H) shows a herniated bowel loop (open arrow) below the pectineus muscle (arrowheads) (arrow in G, femoral vessels.
