Axial non-contrast
FINDINGS: A well-defined rounded hyperdense lesion measuring 2.4 x 2.4 cm is seen within the roof of the third ventricle, which is likely a colloid cyst. Mildly dilated both lateral ventricles, likely due to obstruction at the level of the foramen of Monro. Two frontal VP shunts with their tips lying within the frontal horns of the lateral ventricles are seen in situ. No recent infarction or intracranial hemorrhage is seen.
