I had a CAT scan it showed no hernia. Could I have a hernia or diastasis recti and it not show on the cat scan?

It may have missed a small hernia or diastasis.Kenneth Hughes, MDLos Angeles, CA....................

If you have a small hernia or diastasis recti and the CAT scans were done for other reasons(trauma), the interpretation of the scan may not report it.  Many of this small defect may be ignored by the report. This is why is important to look at the scan or talk to the radiologist. On the other hand, small but clinically significant hernias/diastasis may be diagnosed on physical examination. Best, Dr. RG

A CT scan may not show a small hernia because you are lying on your back when you perform the study.  Thus a small defect may not be seen.  A physical exam my detect a small hernia not seen on CT scan.
