Multimodality imaging of ovarian cystic lesions: Review with an imaging based algorithmic approach

Figure 7 Ovarian serous cystadenoma and endometrioma. A 41-year-old woman with pelvic mass. Axial fat suppressed T1 weighted image (A), axial and sagittal T2 weighted images (B and C) and axial post contrast T1 weighted image (D) showing a right adnexal lesion posteriorly (thick arrow), which has a high signal intensity on T1 weighted image, low signal intensity on T2 weighted image (T2 shading), without any internal debris or septation. Another 7.2 cm lesion in the right adnexa anteriorly (thin arrow) demonstrating low signal intensity on T1 weighted image, high signal intensity on T2 weighted image without internal septations or solid component. Both lesions demonstrate no post contrast enhancement. Left ovary with follicles also noted (arrowhead). On surgery and histopathology, two cystic lesions were seen arising from the right ovary, the posterior lesion was endometrioma and the anterior lesion was serous cystadenoma. UB: Urinary bladder; CX: Cervix.
