From: Incarcerated obturator hernia: pitfalls in the application of ultrasound
Ultrasonograms of the Case 2. a Ultrasound showed the evidence of small bowel obstruction by showing fluid-filled dilated small bowel (arrow) proximal to collapsed distal bowel (broad arrows). b The herniated intestinal segment (
) was delineated posterior to the pectineus muscle (arrows), strangulated at the hernia orifice (broad arrow). c The herniated intestinal segment (
) was delineated posterior to the pectineus muscle (arrows), medial to the femoral artery and vein. d CT scan demonstrated the herniated intestinal segment between the pectineus muscle (arrows) and the obturator externus muscle (broad arrow)
