Is it one cyst? It mentions hemorrhagic but also "complex" and "neoplasm" so not sure if they are referring to the same lesion / cyst. Hemorrhagic cysts are blood filled and typically go away on their own. Complex and neoplasm are more general terms but are typically indicative of cysts that do not go away on their own. However, imaging such as ultrasound are not exact. So they cannot always tell the type of cyst on imaging. The size oftentimes dictates treatment. When cysts are on the small side, the standard is to schedule another ultrasound to see if it has grown, shrunk or gone away.
The large majority of cysts do resolve on their own in 2-3 months, no intervention / surgery needed.
Do you have a copy of the ultrasound report? It should detail the size and characteristics of the cyst(s).
