Dense suprasellar epidermoid cyst. A case report.

O Schubiger, A Valavanis, E Gessaga

    Neuroradiology
    |January 1, 1983
    PubMed
    Summary

    This case study presents a dense epidermoid cyst in the suprasellar cistern, causing headaches and vision loss. Lack of contrast enhancement is key to differentiating it from other suprasellar lesions.

    Area of Science:

    • Neurology
    • Neurosurgery
    • Radiology

    Background:

    • Suprasellar cistern lesions can present with diverse neurological symptoms.
    • Epidermoid cysts are congenital tumors that can occur in the suprasellar region.
    • Accurate radiological differentiation of suprasellar masses is crucial for effective management.

    Observation:

    • A patient presented with headache radiating to the left eye and left-sided quadrant anopsia.
    • Computed tomography (CT) revealed a dense epidermoid cyst in the suprasellar cistern with a density of 62 Hounsfield Units (HU).
    • No significant contrast enhancement was observed after contrast administration.

    Findings:

    • The epidermoid cyst exhibited high density on CT.
    • The absence of contrast enhancement was a notable characteristic.
    • These features suggest a non-enhancing, dense suprasellar lesion.

    Implications:

    • The lack of contrast enhancement is a critical differentiating feature for dense epidermoid cysts.
    • This finding aids in distinguishing epidermoid cysts from other hyperdense suprasellar lesions, potentially altering surgical or treatment planning.
    • Further investigation into the radiological characteristics of suprasellar masses is warranted.
