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.

The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
