Ovarian dysgerminoma: color Doppler ultrasonographic findings and comparison with CT and MR imaging findings.

We describe three cases of ovarian dysgerminoma in which color Doppler sonography demonstrated multilobulated solid ovarian masses with prominent flow signal in the fibrovascular septa. This color Doppler sonographic finding of fibrovascular septa correlated well with the computed tomographic, magnetic resonance imaging, and pathologic findings, and it may suggest the diagnosis of ovarian dysgerminoma.
