Calcifying pseudoneoplasms of the neuraxis (CAPNON) are rare tumours. We describe a CAPNON in the posterior fossa and its associated neuropsychological sequelae to provide further evidence for the role of cerebellum in cognitive function. We report the clinical details, imaging, pre-operative neuropsychological assessment, histological features and management of a patient with such a tumour in the posterior fossa location. Detailed pre-operative neuropsychological assessment identified a number of cognitive deficits that had the hallmarks of dysexecutive syndrome. Post-surgery, there was considerable improvement, most notably on processing speed tasks and selected executive tests. This rare case provides further evidence for the role of cerebellum in cognitive function.

Hydrocephalus is an imprecise term and refers to the imbalance of brain parenchyma and cerebral spinal fluid in the cranial vault. Ventriculomegaly, or enlargement of the ventricular system, is often the more precise term and is therefore preferred. Appropriate imaging and measurement techniques are critical to detect ventriculomegaly and grade its severity.

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.

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.
