Figure 4 Transvaginal ultrasonography(A) Color Doppler transvaginal ultrasonography demonstrates preserved arterial waveform and vascular flow to the right ovary, effectively excluding ovarian torsion. (B) The right adnexa shows a poorly defined 4.0 cm heterogeneous echogenic area consistent with a ruptured hemorrhagic ovarian cyst, without increased peripheral vascularity. Findings support the presence of acute hemoperitoneum, as confirmed by CT.
