Persistently abnormal brain scintigraphy after cerebral infarction

A Faden, F D Rollo

    Journal of Neurology
    |June 13, 1977
    PubMed
    Summary

    Persistent brain scan abnormalities after cerebral infarction were observed in two patients, lasting over a year. This challenges the typical two-to-three-month recovery period for nuclear brain images post-stroke.

    Area of Science:

    • Neurology
    • Radiology
    • Neuroimaging

    Background:

    • Cerebral infarction (stroke) can lead to brain abnormalities detectable by imaging.
    • Nuclear brain imaging typically normalizes within 2-3 months post-stroke.

    Observation:

    • Two patients presented with persistent brain scan abnormalities.
    • Abnormalities remained unchanged at 11 and 17 months post-cerebral infarction.

    Findings:

    • Computed tomography (CT) scans confirmed abnormalities were due to cerebral infarction.
    • Neoplastic processes were ruled out as the cause of persistent abnormalities.

    Implications:

    • This case study suggests cerebral infarction may cause longer-lasting imaging abnormalities than previously thought.
    • Further research is needed to understand the long-term imaging outcomes of stroke.
