Among the non-pleural localizations, the pancreas is extremely rare. In particular, metastasis to the pancreas from the central nervous system (CNS) is extremely rare, with only two cases reported so far. We report a case of recurrence in the pancreas 14 years after the initial complete surgical removal of a tumor in the CNS.<\/jats:p>\n          <jats:p>CASE SUMMARY<\/jats:p>\n          <jats:p>A 68-year-old man with a past medical history of recurrent meningeal hemangiopericytoma, currently referred to as SFT, presented to the hospital with jaundice. The patient was first diagnosed with an 8cm-sized meningeal hemangiopericytoma fourteen years ago and underwent osteoplastic craniotomy. After 16 mo, imaging showed recurrence and he underwent gamma knife radiosurgery (GKRS). 2 years later, imaging showed recurrence again leading to a second GKRS. 5 years later, recurrence was again suspected leading to a second craniotomy. Since then 3 years had passed, and imaging showed a 3.5cm-sized mass lesion on the pancreatic head with obstruction of the pancreatic and bile ducts. Endosonography with fine-needle aspiration biopsy was done preoperatively and aided in the diagnosis of SFT. The patient underwent pylorus-preserving pancreaticoduodenectomy. Pathologic findings of the resected pancreatic specimen, consistent with the previously resected brain specimen, confirmed the diagnosis of SFT.<\/jats:p>\n          <jats:p>CONCLUSION<\/jats:p>\n          <jats:p>The rarity and lack of knowledge about SFTs make suspecting and diagnosing this disease challenging. We believe that a report of metastatic pancreatic SFT from the CNS will contribute to a better understanding of this rare disease.<\/jats:p>","DOI":"10.12998\/wjcc.v11.i35.8416","type":"journal-article","created":{"date-parts":[[2023,12,14]],"date-time":"2023-12-14T03:41:41Z","timestamp":1702525301000},"page":"8416-8424","source":"Crossref","is-referenced-by-count":5,"title":["Metastatic pancreatic solitary fibrous tumor: A case report"],"prefix":"10.12998","volume":"11","author":[{"given":"Kiyoun","family":"Yi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonghyun","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong Uk","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2060","published-online":{"date-parts":[[2023,12,16]]},"reference":[{"key":"B1","unstructured":"Srinivasan VD, Wayne JD, Rao MS, Zynger DL.
