Intracranial solitary fibrous tumors (SFTs) and hemangiopericytomas (HPCs) are rare spindle cell tumors of mesenchymal origin that include benign and malignant neoplasms.
We present a 66-year-old male with a 5-year history of headache and dizziness, with left progressive sensorineural hearing loss over 1 month.
WHO grade II SFT/HPC originating from the internal auditory canal in the left cerebellopontine angle.
surgical resection.
No local recurrence or metastases were observed in the follow-up 3 months after the surgery.
Intracranial SFTs/HPCs are rare mesenchymal neoplasms that are challenging to manage. If the imaging characteristics of tumor are not typical, clinicians should depend on tissue biopsy and immunohistochemistry to make a definitive diagnosis.
颅内孤立性纤维瘤（SFTs）和血管外皮细胞瘤（HPCs）是罕见的间叶源性梭形细胞肿瘤，包括良性和恶性肿瘤。
我们报告一名66岁男性，有5年头痛和头晕病史，1个月内左侧进行性感音神经性听力丧失。
起源于左侧小脑脑桥角内耳道的世界卫生组织II级SFT/HPC。
