A Case of Ruptured Decidualized Ovarian Endometrioma: Usefulness of Serial MRI for Determining Adequate Management

Figure 2

Magnetic resonance imaging (MRI) of the pelvis performed at 27 weeks of gestation. (a) Axial T1-weighted image. (b) Axial T2-weighted image. (c) Sagittal T2-weighted image. (d) Axial diffusion-weighted image (b factor: 1000 s/mm²). (e) ADC map. (f) Coronal T1-weighted image with fat saturation. The cystic lesion disappears (a–e). Ascites around the uterus shows high signal intensity on fat-suppressed T1-weighted images, which is consistent with bloody ascites (f, arrows). Based on serial MRI findings, rupture of the decidualized ovarian endometrioma is suspected.
