I Had A CT Coronary Calcium Screening. My Score Was

I had a CT coronary calcium screening. my score was very low 1. However multiple low attentuation foci within the superior portion of the liver showed 4 discrete lesions measuring 2.7, 1.3 and 2 in the left lobe.The regional soft tissue was unremarkable. The conclusion was a benign hepatic cysts or hemangiomas. Is this common?What does this mean? My doctor has ordered a CT scan to rule out anything.
