Choroidal epithelial cyst. Case report

A Koto, D S Horoupian, K Shulman

    Journal of Neurosurgery
    |December 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    This study identified a choroidal epithelial cyst in an infant, characterized by specific cellular features. Incomplete surgical removal can lead to cerebrospinal fluid secretion and symptom recurrence.

    Area of Science:

    • Neuroscience
    • Pediatric Pathology

    Background:

    • Supratentorial cysts in infants require precise diagnosis.
    • Understanding cyst lining is crucial for predicting behavior and recurrence.

    Observation:

    • Electron microscopy revealed a cyst lined by peg-shaped epithelial cells with abundant organelles and glycogen.
    • Cells exhibited microvilli, a basement membrane, tight junctions, and interdigitations.
    • Associated blood vessels were fenestrated.

    Findings:

    • The observed cellular morphology is characteristic of developing choroidal epithelial cells.
    • Diagnosis of choroidal epithelial cyst was supported by these ultrastructural features.

    Implications:

    • Choroidal epithelial cysts can secrete cerebrospinal fluid even after partial excision.
