A 55-year-old female is presented with transient cerebellar mutism caused by a well-circumscribed left pontine infarction due to postoperative basilar perforator occlusion. Although conventional T2 imaging shows a well-demarcated lesion confined to the pontine region, diffusion tensor imaging shows an asymmetry in fractional anisotropy in the superior cerebellar peduncle. This supports the general hypothesis that cerebellar mutism is caused by functional disruption of the dentate-rubro-thalamic tract. Correlating postoperative anatomic changes to a heterogenic clinical syndrome remains challenging, however.

Background: This study aimed to establish a voxel-based map to predict the occurrence of cerebellar mutism syndrome (CMS) and investigate the relationship between CMS and motor dysfunction.
Method: This multicenter study cohort included 224 patients diagnosed with medulloblastoma at Beijing Children's Hospital (n = 88) and Beijing Tiantan Hospital (n = 136). The dataset was randomly divided into training (n = 95), test (n = 41), and validation (n = 88) datasets.

Catatonia can present with a wide spectrum of psychomotor symptoms and should be considered in the differential diagnosis of hospitalized patients with speech and motor difficulties. Catatonia is defined as the presence of three or more of the following: catalepsy, waxy flexibility, stupor, agitation, mutism, negativism, posturing, mannerisms, stereotypies, grimacing, echolalia, and echopraxia. In this case, a 72-year-old black woman was admitted with difficulty with speech and ambulation and found to have a cerebellar stroke on a brain MRI.

Background: Clinical recognition of the post-operative neurologic sequelae of posterior fossa tumors is inconsistent. This study aimed to characterize functional impairments and recovery trajectories in pediatric patients admitted to inpatient rehabilitation following surgical resection of posterior fossa brain tumors. This study also introduces the Pediatric Physiatric Posterior Fossa Symptom scale (3PFSs) for serial assessment of post-operative symptoms in pediatric posterior fossa brain tumors.
