Brain tumors presenting as small calcified lesions on computerized tomography. Report of three cases

3 children were found to have small focal calcifications on computerized tomography. These lesions ultimately proved to be malignant gliomas in 2 children, and a mixed glioma in the third. Focal calcification on CT scans may pose a diagnostic dilemma for the clinician, and these patients should be carefully followed as possible early brain tumors.
