In brief: Dr should explain
Baby could have one of many types of cystic lesions.
Probably most common is so called multicystic kidney displasia, birth defect where part of, or entire kidney is made up of a bunch of cysts.Opposite kidney is usually normal and child will have a normal life.May have a simple cyst, may have a complex cyst which is usually benign.Can be an obstructed calyx or blocked part of duplex kidney. Ask dr.

In brief: Normal variation
As long as there are less than 6 cysts on the kidney, the chances of any problem are low, get a follow up ultrasound at 6months.

Cystic lesion of kidney, although usually not serious, is not a normal variant. Up to 3 cysts, if fairly small can be considered within normal limits, but no more than that. Please check medical literature & my response to the original question.
