Total resection of a solitary fibrous tumor of the sellar diaphragm: A case report

The present study reports the case of a patient with a vision impairment in the right eye. Head computed tomography revealed a round, hyperdense mass in the sellar and suprasellar regions. Pituitary gland magnetic resonance imaging (MRI) revealed isointensity on T1- and T2-weighted imaging. Tumor-enhanced scanning showed heterogeneous contrast enhancement. The initial diagnosis was that of meningioma or pituitary tumor. A total tumor resection was performed using a right pterional approach under general anesthesia. During surgery, the base of the tumor was located on the sellar diaphragm of the left anterior pituitary stalk. The pathological diagnosis was of a solitary fibrous tumor (SFT). The patient had no post-operative diabetes insipidus or idiopathic pituitary hypofunction. The clinical experience, imaging information and pathological features of SFT in this case report may provide a reference for correct diagnosis and total resection of SFTs in the sella turcica.
