A rare case of giant pelvic retroperitoneal schwannoma.

This report highlights the successful treatment of large pelvic schwannomas and underscores the importance of preoperative embolization. A 40-year-old male presented with a lower abdominal mass and reported pain and numbness in the left lower limb attributed to nerve compression. Preoperative embolization of the main feeding vessels was performed to mitigate intraoperative bleeding. The tumor was completely excised during surgery, with preservation of the hypogastric nerve. Histopathological examination confirmed the diagnosis of schwannoma. We underscore the significant role of preoperative embolization in effectively managing large pelvic tumors, such as schwannomas, by reducing the risk of excessive bleeding.
