So a young male jammed a handlebar into his abdomen, and a CT image demonstrating his problem was shown. But what did it actually show?
By now, you probably realize that clinical information is key. On exam, he had an obvious bulge in his left lower quadrant, more obvious with straining. Looking at the CT (now with a nice arrow), there is a problem over the left side of the abdomen.
This child has so little fat, that it’s difficult to see the problem. If you track the thin layer of fat across the abdomen to the right side of the image, you’ll see that it disappears over the bowel gas. This represents a complete tear through all fascial layers, not just a Spigelian hernia as some readers guessed.
Management consisted of primary repair of the defect. An uneventful recovery can be expected. Unless more bicycle tricks are anticipated.
