Abstract:
Intracranial solitary fibrous tumor（ISFT）is a rare spindle cell central nervous system tumor originating from mesenchymal tissue. There are few reports of ISFT ultrasound findings in China. In this case，the patient，a 59-year-old man，was admitted to the hospital because of "skull tumor found on the top of the head for more than 2 years". The patient found tumor protrusion on the skull at the top of the head 2 years ago，without pain and other feelings. It was as small as a mung bean at first，and gradually increased during the course of the disease. After admission，ultrasound examination was performed，which suggested solid space occupying lesions in the skull. Considering the possibility of eosinophilic granuloma，malignant tumors were to be excluded.CT scan，three-dimensional imaging of skull and MRI scan and enhancement examination of skull were performed，which suggested that the right frontoparietal skull and skull mass shadow occupied the right side，and meningioma may occur. The brain tumor was resected under neuronavigation，and the solitary fibrous tumor was confirmed by postoperative pathology. The author analyzed the pathophysiology，imaging findings，ultrasound characteristics，differential diagnosis of ISFT in detail，in order to improve the understanding of ISFT in clinical work.
