Colorectal Cancer???

I just received my mom's Ultrasound Report from my sister via fax. The details are as below:

*********

Ultrasound Scan of Abdomen

Indications: Acute abdominal pain and vomitting, RIF swelling for 6 months

Ultrasound Findings: Scanning over the RIF swelling shows a large 6x10cm heterogeneous solid mass lesion most likely of large bowel origin. Pelvic free fluid is present. Distended fluid filled bowel loops are visible. Liver appears to be normal with no visible focal mass lesions. Gallbladder and right kidney appear normal.

Impression: Findings suggest an obstructive large bowel mass in the RIF region. Referral for further surgical evaluation is advised.
