ABSTRACT
A 72-year-old male was admitted to our hospital presenting with dyspnea, disorientation, and lethargy over the past seven months. Chest computed tomography (CT) revealed the presence of a large tumor in the left thoracic cavity. Refractory hypoglycemia and a low insulin level were also found. A suspected solitary fibrous tumor of the pleura was revealed by CT-guided percutaneous needle biopsy; we therefore speculated that the patient had developed nonislet cell tumor hypoglycemia due to a solitary fibrous tumor of the pleura. After surgical resection of the tumor, the hypoglycemia disappeared. We diagnosed a solitary fibrous tumor of the pleura on pathologic evaluation of the resected tumor. A high molecular weight form of insulin-like growth factor II was detected in the patient’s serum preoperatively, but not postoperatively.
