Extrapelvic endometriosis is a rare and usually misdiagnosed entity. Some extrapelvic endometriotic lesions are small and nonpalpable, which makes them difficult to locate and remove. Here, we report the use of radioactive seed localization to locate and guide the excision of a small, nonpalpable endometriotic lesion. A 32-year-old woman presented with disabling pain in the right inguinal area. Magnetic resonance imaging and abdominal ultrasound results showed an 11-mm nodule in the abdominal wall, in the vicinity of the groin, consistent with an endometriotic lesion. The radioactive seed was placed within the lesion with the help of ultrasonography, and excision was guided with a portable gamma camera. Complete excision of the endometriotic nodule was achieved. We propose radioactive seed localization as an accurate and feasible technique for the treatment of nonpalpable endometriotic lesions.
