Cerebellar hemorrhage is an unpredictable complication of spinal surgery. We encountered a case of cerebellar hemorrhage presenting with delayed emergence from anesthesia and hemiplegia after resection of an intradural extramedullar tumor from the cervical spine. Postoperative brain computed tomography revealed hematoma in the cerebellar vermis and right cerebellar hemisphere. The patient made a gradual recovery with conservative treatment. Although the mechanism of cerebellar hemorrhage remains speculative, loss of cerebrospinal fluid may play an important role. Cerebellar hemorrhage must therefore be considered in patients with unexplained neurological deterioration or disturbance on emergence from anesthesia after spinal surgery.

Cerebellar Mutism Syndrome in a Patient With Hypertensive Urgency and Ischemia: A Case Report.

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.

Insomnia is a common mental illness seriously affecting people lives, that might progress to major depression. However, the neural mechanism of patients with CID comorbid MDD remain unclear. Combining fractional amplitude of low-frequency fluctuation (fALFF) and seed-based functional connectivity (FC), this study investigated abnormality in local and long-range neural activity of patients with CID comorbid MDD.

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.

Cognitive impairment (CI) frequently occurs in patients with systemic lupus erythematosus (SLE) and may result from neuroinflammation processes and neurovascular changes in the brain. The cerebral hemodynamics underlying SLE with CI (SLE-CI) remain unclear. 97 patients with SLE and 51 heathy controls (HCs) matched for age and gender underwent MRI.

Objective: To explore the clinical manifestations and genetic characteristics of a child with Leukoencephalopathy with ataxia (LKPAT) caused by a CLCN2 gene variant.
Methods: A retrospective analysis was conducted on the clinical data of a child admitted to Hunan Children's Hospital in June 2024 due to "intermittent convulsions for 13 days". Peripheral blood samples were collected from the child and his parents for whole exome sequencing, followed by Sanger sequencing validation and pathogenicity analysis of candidate variants.
