Cerebellar Infarction Management and Outcomes
Summary
The management of cerebellar infarction poses unique challenges due to the confined space of the posterior fossa and the risk of rapid neurological deterioration from oedema and brainstem compression. Early recognition relies on clinical scales such as the National Institutes of Health Stroke Scale for global neurological status and dedicated imaging protocols to quantify lesion size, perfusion mismatch and evolving oedema. Medical therapy focuses on vascular risk control, antithrombotic strategies and osmotic agents to counteract rising intracranial pressure. Surgical interventions, including external ventricular drainage and suboccipital decompressive craniectomy, are life-saving in cases of space-occupying infarction and malignant oedema. Imaging biomarkers such as infarct–oedema volumetry and perfusion–diffusion mismatch guide the timing of surgery and predict functional outcome. Prognostic factors include baseline neurological deficit, infarct location, growth rate of oedema and involvement of the brainstem. Long-term outcomes are assessed by scales such as the modified Rankin Scale, with rehabilitation addressing ataxia, dysphagia and cognitive-emotional deficits. Recent advances in quantitative imaging and standardised surgical approaches have improved survival rates and functional recovery, underscoring the global significance of optimised cerebellar stroke pathways and interdisciplinary care.

The graph below shows the total number of articles in cerebellar infarction management and outcomes across all publications each year (not limited to Nature Index journals).
Technical terms
Cerebellar infarction: Ischaemic stroke affecting the cerebellum, often leading to ataxia and risk of brainstem compression.
Decompressive craniectomy: Surgical removal of part of the skull to relieve intracranial pressure in space-occupying lesions.
Infarct–oedema: Combined volume of ischaemic tissue and surrounding swelling measurable on CT or MRI.
Modified Rankin Scale (mRS): A graded scale (0–6) assessing global disability and functional independence after stroke.
National Institutes of Health Stroke Scale (NIHSS): A quantitative tool to measure the severity of neurological deficits in stroke patients.
ABC/2 method: A rapid formula multiplying three orthogonal diameters of a lesion and dividing by two to estimate infarct or oedema volume.
