Solitary fibrous tumor located in the sella turcica: A report of two cases and review of the literature

摘要

Solitary fibrous tumors (SFTs) of the sella turcica are rare entities, with only four cases reported in the literature thus far. The current study describes two cases of SFT arising from the sella turcica, including presentation of the clinical, imaging and histopathological findings, and the initial treatment strategies and diagnosis, with emphasis on the treatment of the tumor in this unusual location. Magnetic resonance imaging is a useful method for identifying a solid or heterogeneous mass; however, histopathological and immunohistochemical data are required to clarify such diagnoses. The majority of SFTs exhibit clinically benign behavior and have a positive outcome; however, certain SFTs may present malignant features. Although gross total resection of SFTs in the sella turcica is important, subtotal resection with subsequent stereotactic radiotherapy is proposed as an acceptable alternative. Furthermore, careful and long-term follow-up of patients with SFT of the sella turcica is required as the clinical outcome is unpredictable.
