CT - CT brain three weeks after surgery
Axial non-contrast
FINDINGS: Status post-frontal burr hole craniotomy. The previously noted colloid cyst at the level of the foramen of Monro has largely been surgically removed, leaving behind a small residual hypodensity. Mild bleed is seen in the lateral ventricles (likely post-surgical). Some hypodensities are seen in the right frontal lobe and left basal ganglia region which are likely post-surgical changes. A VP shunt is seen in place with its tip lying in the substance of the right frontal lobe.
