Value of Transvaginal Two-Dimensional Contrast-Enhanced Ultrasonography in Diagnosing Atypical Ovarian Corpus Luteum Hematoma

Figure 2

AT-OCLH (a) 2D gray-scale and CDFI examination: the mass showed inhomogeneous solid echogenicity. As the cyst wall was thick, blood flow on the cyst wall could be misdiagnosed as vessels within the tumor (arrow). (b) 2D-CEUS: annular perfusion with no contrast agent perfusion in the mass, indicating that the misdiagnosed vascular flow is big nourishing blood vessels (arrow), and the perfusion intensity of the cystic wall is slightly higher than the surrounding tissue.
