What Does This Ultrasound Report And CAT Scan Indicate?

I am wondering if I need to contact an Oncologist for a hypoechoic lesion (11x6mm anterior mid body) from an ultrasound test. Done 5/30/14 I was sent for a cat scan which showed low attenuation lesion in the pancreas measuring 7mm. Done 6/11/14. Thank you. Joann

Hi,
Thanks for writing in.

A hypoechoic lesion in the mid part of pancreas measuring 11 x 6 mm is usually a fluid filled structure. CT scan is required in such cases and you have got it done. The CT scan shows a 7 mm low attenuation lesion in the same place. A low attenuation lesion again is most likely to be a cyst. It is important to know if this lesion is showing enhancement. There is also a technical parameter called HU value in CT scan. If the HU value is less than 20 then it is confirmed to be a fluid containing cystic structure. It is important to have at least one consultation with the oncologist and discuss the reports in detail. Repeat ultrasound scan might be required in 6 months. This is to make certain that it is a benign cystic lesion and not a serious concern. Please do not worry.
