    Computed tomography (CT) scans can help diagnose craniopharyngiomas by identifying calcification, cysts, or contrast enhancement. These characteristic findings are key for diagnosing this rare brain tumor in both children and adults.

    Area of Science:

    • Radiology
    • Pediatric Radiology
    • Neuroradiology

    Background:

    • Craniopharyngiomas are rare tumors often presenting in the sellar region.
    • Accurate pre-operative diagnosis is crucial for effective management.
    • Characteristic imaging findings on computed tomography (CT) can aid in diagnosis.

    Purpose of the Study:

    • To retrospectively analyze computed tomographic (CT) findings in surgically confirmed craniopharyngiomas.
    • To identify characteristic CT features that may aid in the pre-operative diagnosis of craniopharyngiomas in children and adults.
    • To discuss unusual presentations of craniopharyngiomas, particularly in adult patients.

    Main Methods:

    • Retrospective review of computed tomographic (CT) examinations.
    • Analysis of 28 children and 12 adults with surgically proved craniopharyngiomas.

  • Evaluation for the presence of calcification, cysts, and contrast enhancement on CT scans.

    • Main Results:

    • At least two of three key findings (calcification, cyst, contrast enhancement) were present in 80% of pre-operatively examined children (8/10) and 50% of pre-operatively examined adults (2/4).
    • Some patients did not receive contrast enhancement in their initial CT examinations.
    • The study also noted variations in tumor presentation, especially in adult cases.

    Conclusions:

    • Computed tomography (CT) demonstrates characteristic findings suggestive of craniopharyngioma, including calcification, cystic components, and contrast enhancement.
    • These imaging features are valuable for pre-operative diagnosis in pediatric and adult populations.
    • Awareness of potential variations in presentation, particularly in adults, is important for accurate diagnosis.
