We report a case of a giant pelvic SFT with DPS, which was managed with preoperative arterial embolization and complete excision.  \nCase Presentation: 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 × 15cm) 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.  \nConclusion: The combination of preoperative TAE and surgical resection appears to be an effective therapeutic strategy for DPS-associated SFT.  \n1 | Introduction and Background  \nSolitary fibrous tumor (SFT) is a rare mesenchymal neoplasm of fibroblastic origin. In fewer than 5% of cases, it is associated with refractory hypoglycemia, known as Doege–Potter syndrome (DPS) [1, 2] . This paraneoplastic hypoglycemia results from tumor-derived secretion of high-molecular-weight insulinlike growth factor 2 (IGF-II) [3] .  \nSince its first report in 1930, the management of DPS has remained non-systematic due to its rarity [4, 5]. Herein, we present  \na case of pelvic SFT with DPS successfully managed with preoperative transcatheter arterial embolization (TAE) and complete excision.  \n2 | Case Presentation  \nA 77-year-old man was emergently transported due to loss of consciousness. Examination revealed hypoglycemia and an intrapelvic mass. He required continuous total parenteral nutrition (TPN) due to severe hypoglycemia.
