MRI confirmed features in keeping with endometriosis of the canal of Nuck. Intervention(s) Open excision of the lesion. Main outcome measure(s) Symptom free at two months. Results Histological analysis confirmed the left-sided lesion to be endometriosis. This is an unusual presentation of canal of Nuck endometriosis being left-sided and arising in the absence of evidence of pre-existing pelvic endometriosis, which was successfully managed by surgical excision.
