Noninvasive Duplex Ultrasound Findings of Left

Endometriosis is described as the presence of endometrial tissue found at sites outside of the uterus. Symptoms can include pain, hemorrhage, and/or infertility. Typically, computer tomography is utilized to make the diagnosis, which requires surgical intervention to confirm and treat. Extra-abdominal endometriosis, presenting as painful groin mass, is uncommon. In the vast majority of cases, it occurs in the right inguinal region. However, in the inguinal region, duplex ultrasound can be utilized to make the diagnosis and, depending on the clinical setting, may obviate the need for biopsy or excision. We present a rare case of left-sided inguinal endometrioma diagnosed by duplex ultrasonography
