Computed Tomography and Magnetic Resonance Imaging Diagnosis of Intracranial Solitary Fibrous Tumor: A Clinical Case Analysis

Intracranial solitary fibroma tumor (ISFT) is a kind of mesenchymal tissue-derived spindle cell tumor. Patients’ disease progression vary according to the course and location of the tumor. Due to its rarity, radiologists and clinicians lack a comprehensive understanding of ISFT. Hence, the preoperative misdiagnosis rate is high. This case report describes a 52-year-old male patient with intracranial solitary fibroma who presented with headache and weakness of both lower extremities. He underwent radiological examination, including computed tomography (CT) and magnetic resonance imaging (MRI), and was diagnosed with acoustic neuroma. After postoperative pathological tissue biopsy, he was diagnosed with ISFT. He was reviewed one and a half years after surgery; there was no significant discomfort in addition to the paralysis of the left facial nerve and swelling of the left side of the face. This case report retrospectively analyzes the radiological scans and the clinical data of the patient to summarize the key CT and MRI features of ISFT, improving the accuracy of the preoperative diagnosis of this rare disease, and contributing to current knowledge of the precise treatment of ISFT.
