CT scan of the abdomen and pelvis (10/13/2007). Axial (a) and (b) and Coronal (c) images obtained through the pelvis demonstrate a complex solid and cystic mass in the left adnexa (whie arrow) measuring 3.2 x 2.4 cm.

Restaging CT scans of the chest, abdomen, and pelvis (Figure 1), revealed a mixed cystic and solid structure in the left adnexal region, measuring 3.2 x 2.4 cm, which was felt to represent ovary with a complex cyst.
MRI of the pelvis (10/29/2007). Coronal T2-weighted images (a) and (b) demonstrate a left adnexal mixed solid and cystic mass (white arrow). The hyperintense T2 area represents the cystic component, and the isointense T2 area is the soft tissue component of the mass. Sagittal T2-weighted image (c) demonstrates the cystic component of the mass (white arrow). On coronal T1 Fat-Sat postcontrast image (d), the solid component of the mass enhances homogeneously after gadolinium administration; however, the cystic component is hypointense (white arrow.)

Further evaluation with MRI performed 16 days later (Figure 2) revealed a lesion with high-signal intensity on T2-weighted images and low signal intensity on T1-weighted images.
CT scan of the abdomen and pelvis (1/12/208). Axial (a) and (b) and coronal (c) images of the pelvis demonstrate a large, predominantly hypodense, left adnexal soft tissue mass (white arrow). Note that the cystic component of the mass has resolved and the soft tissue portion has significantly increased.

Repeat CT scan performed in 2 weeks (Figure 3) revealed further increase in the size of the left adnexal mass with interval resolution of the cystic component.
