I Recently Had An MRI And A Ct Scan In

i recently had an MRI and a ct scan in which a cysts appeared on my pancreas. the report stated that the cysts were described in the radiology report as 1cm located on the superior head and a subcentimeter on the inferior head. no complex enhancement likely a congenital cyst. No pancreatic ductal dialation. Both common bile and main pancreatic duct are normal caliber. Question... What could have caused this? also noted Prominent parapelvic cyst of left kidney and small cortical cyst of right kidney noted. Again what could have cased this? I saw a GI doc but was not given any info.
