We report a case of intracerebral cystic schwannoma in the temporal fossa manifested as a gradually worsening headache in a 49-years-old woman. Computed Tomography (CT) and magnetic resonance imaging (MRI) showed a left temporal partly cystic, partly solid mass. The preoperative diagnosis was astrocytoma or glioblastoma multiforme (GBM), but microscopic examination of the mass showed the characteristic pattern with cellular Antony A component. Immunohistochemically, the tumor was positive for S-100 protein. These findings are consistent with a schwannoma. Intracerebral schwannomas not related to cranial nerves are rare and most reported cases involved young patients.

Background: Previous studies suggest a positive relationship between higher hospital endovascular thrombectomy (EVT) volume and improved outcomes. We investigated this association using the National Inpatient Sample (NIS) database from 2016 to 2020.
Methods: A cross-sectional analysis of the NIS examined the relationship between hospital EVT volume and outcomes.

Traumatic aneurysms represent less than 1 percent of intracranial aneurysms and middle meningeal artery pseudoaneurysms are even rare. Traumatic aneurysms are usually pseudoaneurysms formed by the rupture of all the layers of the vessel wall. They are associated with high mortality as they can present as epidural, subdural, and rarely intraparenchymal hematoma.

To investigate the clinical characteristics of patients with hydrocephalus after hypertensive cerebral haemorrhage (HICH) and to analyse the relevant factors affecting the prognosis. A total of 500 patients with HICH admitted to the neurosurgery department of The First Hospital of Hebei Medical University between January 2020 and July 2024 were retrospectively analysed. The clinical data of the patients were collected, the occurrence of hydrocephalus within 3 months after discharge was followed up, and the patients were divided into the occurrence group and the non-occurrence group.

Background: There are sex disparities in the risk of ruptured intracranial aneurysm (IA), but which sex-specific factors are related to ruptured IA remains inconclusive.
Methods: Data from electronic medical records from two tertiary hospitals, collected between January 2012 and December 2019, were analyzed for this study. All IAs were confirmed by computed tomographic angiography or digital subtraction angiography.
