    Area of Science:

    • Neurology
    • Radiology
    • Medical Imaging

    Background:

    • The cisterna magna is a cerebrospinal fluid-filled space in the brain.
    • Enlargement of this space, termed mega cisterna magna, can be incidentally found during neuroimaging.

    Purpose of the Study:

    • To determine the incidence of mega cisterna magna in a large patient cohort.
    • To assess the clinical significance and necessity for further investigation of incidentally discovered mega cisterna magna.

    Main Methods:

    • Retrospective analysis of 3000 computerized tomography (CT) scans.
    • Identification and documentation of cases with enlarged cisterna magna.

    Main Results:

    • Eleven cases of enlarged cisterna magna were identified, representing an incidence of approximately 0.37%.

  • No specific symptoms were associated with the enlarged cisterna magna findings in the identified cases.

    • Conclusions:

    • Mega cisterna magna is an incidental radiological finding.
    • Isolated mega cisterna magna does not appear to be clinically significant and may not warrant further diagnostic workup or treatment.
