Intracranial solitary fibrous tumors (SFTs) are rare primary central nervous system neoplasms. Currently, the neurosurgical management of patients with SFTs relies on limited literature and primarily involves total tumor resection. The necessity of radiation therapy in the postoperative period remains a topic of debate. Symptoms associated with this disease are nonspecific and are primarily dependent on the tumor's location and size.

This article presents a case report of surgical treatment of a patient with an SFT located at the right petrous apex and tentorium, extending into the middle and posterior cranial fossae. The surgery was performed using an infratemporal fossa approach combined with intraoperative neuronavigation. After internal decompression, significant bleeding was observed both from the tumor tissue itself and the altered underlying bone. Postoperative brain MRI revealed that a near-total resection of the tumor (96.4%) was achieved while prioritizing the avoidance of potential hemorrhagic complications related to the removal of the difficult-to-reach cavernous sinus extension of the tumor. After the surgery, the patient showed improvement in her neurological and overall clinical status. Thus, the treatment method employed has proven effective and can be recommended for the management of SFTs of the central nervous system.

Keywords: Brain, solitary fibrous tumor, meningeal tumor, microsurgical treatment, clinical case.
