Supplemental Material for: Coexistence of a Retrorectal Tailgut Cyst and an Incidental Coccygeal Chordoma in a 20-Year-Old Woman: A Case Report figshare admin karger (2628495) Niv Gronovich (25075654) Ofra Carmel (25075656) Victoria Doviner Sherman (25075658) Shlomo Yellinek (25075660) Medicine Medicine <p dir="ltr">Introduction: The retrorectal space is a complex anatomical region that can harbor diverse lesions, including rare congenital hamartomas like tailgut cysts and malignant tumors like chordomas. We report the highly unusual coexistence of these two entities in a single patient.</p><p><br></p><p dir="ltr">Case Presentation: A 20-year-old woman presented with a 3-month history of lower abdominal pain. Imaging revealed a 45 mm retrorectal cystic lesion adjacent to the rectum. Resection was performed using a posterior Kraske approach with coccygectomy to improve exposure. Histopathological examination confirmed a tailgut cyst. Unexpectedly, examination of the resected coccyx revealed an incidental 3 mm microscopic chordoma within the medullary cavity.</p><p><br></p><p dir="ltr">Conclusion: This case underscores the complexity of the presacral space and demonstrates that apparently uninvolved tissue removed for surgical access may harbor occult pathology. It emphasizes maintaining a high index of suspicion for malignancy even in young patients with benign-appearing cystic lesions.</p> 2026-09-19T10:27:23Z Dataset Dataset 10.6084/m9.figshare.33942067.v1 https://figshare.com/articles/dataset/Supplemental_Material_for_Coexistence_of_a_Retrorectal_Tailgut_Cyst_and_an_Incidental_Coccygeal_Chordoma_in_a_20-Year-Old_Woman_A_Case_Report/33942067 CC BY 4.0
