Ultrasound-Guided Preoperative Wire Localisation of Post-Caesarean Section Abdominal Wall Endometrioma

Anterior abdominal wall endometriosis (AWE) refers to the presence of endometrial tissue superficial to the peritoneum, lying within the subcutaneous tissue.It is rare, and the proposed aetiology is iatrogenic implantation of endometrial cells during surgery, with caesarean section accounting for more than half of the cases.Ultrasound, computed tomography, or magnetic resonance imaging (MRI) can be utilised for the diagnosis.Herein, we report the successful utilisation of the technique of ultrasound (US)-guided wire localisation for surgical removal of the post-caesarean section AWE with resultant better patient outcome.A 29-year female with two previous caesarean sections presented to the gynaecology clinic with a history of a lump at the caesarean section scar site for two years.The pelvic MRI confirmed the diagnosis of scar endometriosis.The patient underwent excision of scar site endometriosis after US-guided wire localisation.The lesion was excised completely and further confirmed on specimen sonography and histopathology.
