Schwannomas are benign nerve tumors arising mainly in the intracranial, cervical, or lumbar regions. We describe the case of a presacral schwannoma in a 42-year-old woman. This atypical localization is most often discovered by symptoms related to compression of nervous structures. Our patient presented only with deep dyspareunia. The schwannoma was diagnosed on MRI which revealed a presacral hyperintense mass with an antero-posterior diameter of 47 mm opposite the S3 sacral orifice. After 6 years of follow-up, the mass was resected because of worsening dyspareunia and sudden lesion growth. The resection was performed through an open abdominal anterior approach and resulted in alleviation of the symptoms without postoperative complications. To our knowledge, this is the first case of pelvic schwannoma expressing a gynecological symptom such as dyspareunia.
