Overview
Other Imaging Findings
- Radiologic evaluation of small endometriotic implants is limited; therefore, the radiologist's role is generally to identify and evaluate endometriomas.
US
- Adnexal mass with diffuse low-level internal echoes and absence of particular neoplastic features is highly likely to be an endometrioma if multilocularity or hyperechoic wall foci are present.
MRI
The diagnostic MR imaging findings for ovarian endometriomas are:
- Adnexal cysts of high signal intensity on both T1- and T2-weighted images or
- T2 shading: High signal intensity on T1-weighted images and low signal intensity on T2-weighted images (shading). The dense concentration of cyclic hemorrhage and the high viscosity of the contents in the endometrioma cause T2 shortening and produce shading.
These adnexal lesions are often multiple.
