EASY TO MISS FINDING ON ABDOMINAL CT SCAN



To err is human…….an old saying and true with everybody!




Radiologists too can miss certain findings while reading CT scans of the abdomen. MDCT has thrown new challenges to radiologists as more and more details can be seen now. 

Errors cannot be eliminated, but we can reduce them and should be our AIM!

Here is a short list of findings that are easily overlooked while reading abdominal CT scans. It is based on mistakes I have made myself or observed when radiology residents report. 

A little attention and adhering to a protocol helps. I typically, avoid looking for the obvious finding first. I have a checklist, which I follow and try to avoid looking at the most obvious findings first. 

Here is my list. And I urge you also to keep track of such errors you encounter. Most important is to share with your fellow radiology colleagues!

1. Lung lesions: Lung bases are covered need to be checked in all abdominal CT scans. You may pick metastatic disease.

2. Spine fracture: If you view spine in sagittal as a routine in MDCT of abdomen, you will not miss them.

3. Liver lesions in the left lobe: Left lobe is usually small as compared to the right lobe and one is likely to miss lesions in them, especially at the dome or inferior edge of segment III. Remember to use a metastatic window while looking for liver lesions (narrow window with high contrast).

4. Pancreatic tail lesions.

5. Incidental adrenal nodules.

6. Ureteric calculus in a patient with suspected appendicitis.

7. Early / minimal hydronephrosis

8. Small angiomyolipoma
