Radiologic findings in Hirschsprung's disease?
Understand the Problem
The question is asking for the radiologic findings associated with Hirschsprung's disease, which involves understanding the abnormality of the rectum and the colon that characterizes this condition. This may involve the review of imaging techniques such as X-rays or contrast studies.
Answer
Dilated proximal colon with a narrowed distal segment and empty rectum.
Radiologic findings in Hirschsprung's disease typically show a dilated proximal colon and a narrowed distal segment, indicating a bowel obstruction. An empty rectum or a cone-shaped narrowing towards the distal gut can also be seen.
Answer for screen readers
Radiologic findings in Hirschsprung's disease typically show a dilated proximal colon and a narrowed distal segment, indicating a bowel obstruction. An empty rectum or a cone-shaped narrowing towards the distal gut can also be seen.
More Information
Hirschsprung's disease is diagnosed using radiographic imaging due to the loss of nerve cells in the colon, which impairs bowel movement. The contrast enema can often reveal a clear transition zone where the dilated bowel abruptly changes to the narrowed segment.
Tips
A common mistake is overlooking the transition zone on imaging, which is vital for diagnosing Hirschsprung's disease. Always look for the sudden change from dilated to narrowed bowel.
