    Computed tomography (CT) scans revealed calcifications in most oligodendroglioma cases. Contrast enhancement on CT scans indicated malignant histological features in these brain tumors.

    Area of Science:

    • Neuroradiology
    • Oncology
    • Neuropathology

    Background:

    • Oligodendroglioma is a primary brain tumor.
    • Accurate diagnosis and grading are crucial for treatment planning.

    Purpose of the Study:

    • To evaluate the computed tomography (CT) imaging features of oligodendroglioma.
    • To correlate CT findings with histological malignancy.

    Main Methods:

    • Computed tomography (CT) scans were performed on 22 patients.
    • Histological verification of oligodendroglioma was obtained.
    • CT findings, including calcifications and contrast enhancement, were analyzed.

    Main Results:

    • Calcifications were observed in 20 out of 22 oligodendroglioma cases.

    Related Experiment Videos

  • Contrast enhancement was present in 14 cases.
  • All cases with contrast enhancement exhibited malignant histological features.
  • A fluid-fluid level, indicating a cystic component, was seen in 2 malignant tumors.

    • Conclusions:

    • CT findings like calcifications are common in oligodendroglioma.
    • Contrast enhancement on CT is a significant indicator of malignant oligodendroglioma.
    • CT can help identify cystic components in malignant oligodendrogliomas.
