| * Radiologic evaluation of small endometriotic implants is limited; therefore, the radiologist's role is generally to identify and evaluate endometriomas.

|
| |
| * 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.
