hello,
crystals in the ovary means she might be having just an
ovarian cyst or a non cancerous
ovarian tumor called stromal
leydig cell tumor.
we need more information on her gynecological history if any family history if she experiences any other symptoms.
i would strongly suggest take her to be seen by a gynecologist for further workup,follow up and treatment.
hope have been able to answer your query
