Solitary fibrous tumor (SFT) is an uncommon spindle-cell mesenchymal tumor of probable fibroblastic derivation that most often occurs in the pleura, where it is typically benign. This report describes a case of a large SFT that arose in the buccal space, and includes computerized tomography, magnetic resonance imaging, and positron emission tomography (PET) findings. (18)F-Fluorodeoxyglucose (FDG) PET axial imaging showed weak abnormal accumulation of FDG in the left buccal region. The tumor was located behind the posterior wall of the maxilla, adjacent to the medial aspect of the coronoid process and was compressed between the coronoid and maxillary alveolar processes. We resected it with the use of a transoral approach in combination with coronoidectomy. Coronoidectomy was chosen because it facilitated safe removal of the tumor by improving its visibility and providing enough working space to resect it through a transoral approach.
孤立性纤维瘤（SFT）是一种少见的梭形细胞间叶源性肿瘤，可能来源于成纤维细胞，最常发生于胸膜，通常为良性。本报告描述了一例发生于颊部的巨大 SFT，包括计算机断层扫描、磁共振成像和正电子发射断层扫描（PET）结果。（18）F-氟脱氧葡萄糖（FDG）PET 轴位成像显示左颊部有轻度异常 FDG 聚集。肿瘤位于上颌骨后壁后面，毗邻喙突的内侧，被喙突和上颌牙槽突之间挤压。我们采用经口入路联合喙突切除术切除肿瘤。选择喙突切除术是因为它通过改善肿瘤的可视性并提供足够的工作空间，使肿瘤通过经口入路安全切除。
