Cerebellar infarction: a clinical and CT study

S U Ho, K S Kim, R A Berenberg

    Surgical Neurology
    |November 1, 1981
    PubMed
    Summary

    Cerebellar infarction, identified via computed tomography (CT), affects specific arterial territories. Clinical outcomes are not directly linked to infarct size, but rapid sensorium decline signals need for surgical decompression.

    Area of Science:

    • Neurology
    • Radiology
    • Neurosurgery

    Background:

    • Cerebellar infarction is a critical neurological event.
    • Computed tomography (CT) is a primary diagnostic tool for evaluating brain parenchyma.
    • Understanding the vascular territories involved is crucial for diagnosis and management.

    Observation:

    • A 5-year review identified seven cases of cerebellar infarction on CT scans.
    • CT revealed hypodensities in the territories of the posterior inferior cerebellar artery (PICA) and superior cerebellar artery (SCA).
    • Associated findings included hydrocephalus and effacement/displacement of the fourth ventricle in some patients.

    Findings:

    • Cerebellar infarcts were localized to PICA and SCA distributions.
    • No direct correlation was observed between infarct location/extent and clinical outcome.
    • Rapid decline in the patient's level of consciousness (sensorium) was the most significant predictor for surgical intervention.

    Implications:

    • CT imaging effectively delineates cerebellar infarction patterns related to specific arterial supplies.
    • Clinical deterioration, particularly sensorium changes, is a key indicator for considering surgical decompression in cerebellar infarction.
    • Further research may elucidate the precise relationship between vascular territory, infarct volume, and neurological deficits.
