# Solitary Fibrous Tumor With Doege–Potter Syndrome Successfully Treated With Preoperative Transcatheter Arterial Embolization and Complete Excision; A Case Report

## TL;DR

A patient with a rare tumor causing severe low blood sugar was successfully treated with embolization and surgery.

## Contribution

Demonstrates successful treatment of DPS-associated SFT using preoperative embolization and complete excision.

## Key findings

- Preoperative TAE reduced bleeding risk during surgery for a giant pelvic SFT.
- Complete tumor resection resolved hypoglycemia in a DPS patient.
- The patient remained recurrence-free for 11 months post-surgery.

## Abstract

Doege–Potter syndrome (DPS) is a rare paraneoplastic phenomenon of severe hypoglycemia associated with solitary fibrous tumors (SFT). We report a case of a giant pelvic SFT with DPS, which was managed with preoperative arterial embolization and complete excision.

This report describes the case of a 77‐year‐old patient with persistent hypoglycemia and a giant pelvic mass. He required continuous total parenteral nutrition (TPN) for severe hypoglycemia. CT showed a giant hypervascular mass (20 × 18 × 15 cm) in the pelvic space. Tumor biopsy showed SFT. To avoid intraoperative brisk bleeding, transcatheter arterial embolization (TAE) of the main feeders was performed 1 day before surgery. The tumor was completely resected via midline abdominal incision. Hypoglycemia resolved postoperatively. He was recurrence‐free for 11 months after surgery.

The combination of preoperative TAE and surgical resection appears to be an effective therapeutic strategy for DPS‐associated SFT.
