Sonographic findings of inguinal endometriosis.
OBJECTIVE
The purpose of this series was to describe the sonographic findings of inguinal endometriosis.


METHODS
This was a retrospective analysis of 3 cases of inguinal endometriosis. The following gray scale and color Doppler sonographic features were analyzed: size, shape, echogenicity, and blood flow within inguinal endometriosis.


RESULTS
The size of inguinal endometriosis ranged from 3.1 to 4.2 cm (mean, 3.7 cm). All 3 cases were cystic lesions. Two of 3 cases were lesions with internal septa. On color Doppler sonography, 1 of the 3 cases showed a few flow signals within the lesion, whereas in 2 of the 3 lesions, no blood flow could be identified within the lesions.


CONCLUSIONS
Although the sonographic features of inguinal endometriosis may be variable, endometriosis should be included in the differential diagnosis when unilocular and multilocular cystic masses are seen on sonography.
