Cerebellar mutism syndrome (also known as posterior fossa syndrome) has been mostly seen in pediatric patients after surgery for neoplastic disease and is characterized by mutism, with variable symptoms such as emotional lability, ataxia, apraxia, and hypotonia. While the mechanism is not precisely defined, it is thought to result from disconnections between the cortical and cerebellar brain networks. Presentation in adult patients is rare, with various etiologies including posterior fossa ischemia, hemorrhage, and tumors being most reported. We report a case of adult-onset posterior fossa syndrome in a woman with a previous right hemisphere cerebellar stroke, in the context of contralateral cerebellar involvement and hypertensive urgency. The etiology, clinical presentation and course, and management of posterior fossa syndrome are discussed.

Objective: To investigate the independent risk factors for short-term mortality in patients with spontaneous cerebellar hemorrhage (SCH) based on Mimics software of medical image control system.
Methods: The clinical data of SCH patients treated at Shengjing Hospital of China Medical University from January, 2010 to December, 2021 was retrospectively analyzed and compared, including gender, age, underlyin g diseases, Glasgow coma scale (GCS) and blood pressure at admission, laboratory indicators, imaging data, and short-term (3 weeks after onset) survival status. The imaging examination parameters were accurately calculated using Mimics software, including hematoma volume, longest diameter, and maximum cross-sectional area of cerebellar hemorrhage.

Background: Postoperative pediatric cerebellar mutism syndrome (ppCMS) poses serious morbidity after posterior fossa tumor surgery. Neuroimaging studies aim to understand its pathophysiology, yet these vary in methodology and outcome measures. Therefore, we systematically reviewed the current literature to evaluate the evidence for differences in neuroimaging features between children with and without ppCMS.

Background: Petroclival meningiomas are still a neurosurgical challenge due to their proximity to cranial nerves and cerebral vasculature along the surgical corridor. The usual extension of large petroclival meningiomas is along the posterior fossa, frequently compromising and displacing adjunct cranial nerves such as the sixth and seventh-eight cranial nerve complex with brainstem compression, causing progressive neurological deficit and severe headache. The goal of sizeable petroclival meningioma surgery treatment is a maximal resection with preservation of neurological function.
