Endometriosis of the Rectus Abdominis Muscle: A Rare Cause of Emergency Department Visit; Case Report
Endometriosis of the Rectus Abdominis Muscle
Introduction: Endometriosis affects approximately 10% of the reproductive age woman. Although the most common affected sites are ovaries, sacrouterine ligament, rectovaginal septum, and pelvic peritoneum, it can be located in any organ. Endometriosis of rectus abdominal muscle independent from the cesarean section incision is extremely rare.
Case Presentation: A 31-years-old female was admitted to the emergency department with periodical abdominal pain and distension complaints. Ultrasonography and computed tomography revealed a heterogeneous mass in the rectus abdominis muscle. Surgical excision was performed. Histopathologic examination showed endometrial tissue with glandular and stromal elements within the muscularis propria.
Conclusion: Endometriosis should be kept in mind in the differential diagnosis of atypical pain and mass of the abdominal wall in the emergency settings.
