Objective To summarize the clinical features of intracranial intraparenchymal and intraventricular schwannomas.Methods A total of 13 patients with intracranial intraparenchymal and intraventricular schwannomas who were diagnosed and treated in Xiangya Hospital of Central South University from June 2010 to June 2020， and related data were analyzed， including general information， symptoms， signs， radiological features， surgical procedures， and treatment process.Results The 13 cases of intraparenchymal or intraventricular schwannomas did not originate from the cranial nerve， accounting for 0.45% of all cases of schwannomas during the same time period of time. The age of the patients ranged from 1 to 71 years， with a mean age of 35.7 years， and there were 9 male patients and 4 female patients， with a male/female ratio of 2.25：1.00. The time to disease onset ranged from 4 days to 3 years， and headache was the most common initial symptom， followed by seizures. Most tumors were located in the frontal lobe， followed by the cerebellar hemispheres and the temporal lobe. intralesional cysts and peritumoral edema were common radiological features， and calcification was observed in one case. All 13 cases were misdiagnosed as other tumors before surgery， and most of them were diagnosed as glioma or meningioma.Conclusion Intracranial intraparenchymal and intraventricular schwannomas are rare neoplasms， and it is difficult to differentiate them from other solid tumors before surgery. The histogenesis of this tumor remains unknown， and surgery is the preferred treatment option. A favorable prognosis is observed for all types except malignant schwannoma.
