What is a multi-striated ovarian cyst?

Hemorrhagic cyst? It may represent a hemorrhagic ovarian cyst. A unilocular thin-walled cyst in the adnexal region with internal fine interdigitating septations/fibrin-strands, which give a fine reticular appearance (multi-striated?), good through transmission, and color doppler showing no flow in these fine septations is consistent with hemorrhagic cyst. Discuss with your radiologist on what his thoughts were.
