Parietal endometriosis is a rare clinical entity whose pathophysiology remains unclear. It occurs most often after gynecological or obstetrical surgery. We report the case of a patient with cyclic pain at the level of the caesarean section scar. With clinical examination, two nodules on both sides of the scar increase in size associated with pain punctuated by the menstrual cycle. Pelvic ultrasonography showed two nodular formations of hypoechoic, avascular Doppler echo, apparently in relation to endometriotic nodules. Hence the decision to excise the lesion widely, whose anatomopathological study confirms the diagnosis of parietal endometriosis. Postoperative follow-up was straight forward with a follow-up of 12 months without recurrence of lesions or pain. Through our case, we will insist on the characteristics of this pathology, which will allow the practitioner to understand the interest of the diagnosis and early management of this condition as well as the possibility of its prevention during each gynecological surgery or obstetric.
