| There is diffuse hypodensity with a loss of grey-white matter differentiation in the right frontal lobe. A few hyperdense foci are observed within this area consistent with blood. A hyperdense linear structure, probably a cortical vein, overlies the abnormality extending to the superior sagittal sinus which is also hyperdense. A 5 mm hyperdense lesion is seen in the roof of the 3rd ventricle consistent with a colloid cyst. |
