# A rare case of giant pelvic retroperitoneal schwannoma

## TL;DR

A 40-year-old man with a large pelvic schwannoma was successfully treated with preoperative embolization and surgery.

## Contribution

The study emphasizes the effectiveness of preoperative embolization in managing large pelvic schwannomas.

## Key findings

- Preoperative embolization reduced intraoperative bleeding risk during schwannoma removal.
- Complete tumor excision was achieved with preservation of the hypogastric nerve.
- Histopathology confirmed the diagnosis of schwannoma.

## Abstract

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.
