Dense cystic craniopharyngiomas.

I F Braun, R S Pinto, F Epstein

    AJNR. American Journal of Neuroradiology
    |March 1, 1982
    PubMed
    Summary

    Dense cysts in craniopharyngiomas, often overlooked, are caused by high protein concentration. This finding helps differentiate cystic from solid tumors based on lesion characteristics, not just CT density.

    Area of Science:

    • Radiology
    • Neuro-oncology
    • Medical Imaging

    Background:

    • Craniopharyngiomas are tumors often presenting with calcification, contrast enhancement, and cysts on CT scans.
    • Typically, cystic craniopharyngiomas exhibit hypodense centers, but hyperdense cysts are less commonly emphasized.

    Observation:

    • This study reports four cases of craniopharyngiomas with isodense to hyperdense cysts.
    • Analysis of cyst aspirates revealed high intracystic protein concentration as the primary cause of increased density.

    Findings:

    • Computed tomography (CT) findings of high intracystic protein concentration correlate with hyperdense cysts in craniopharyngiomas.
    • The study emphasizes that lesion characteristics, rather than solely attenuation coefficients, are crucial for distinguishing dense cystic from solid craniopharyngiomas.

    Implications:

    • Understanding the cause of hyperdense cysts aids in accurate diagnosis and characterization of craniopharyngiomas.
    • This distinction is vital for appropriate treatment planning and patient management in neuro-oncology.
