progressive deterioration within 2 days. MRI performed today showing
colloid cyst with acute hydrocephalus. Mannitol with decadron
started and within 3-4 hours the patient was operated. Right

contaminating the CSF. After that, the ventricles became lax and it
was possible to see the floor of the third ventricle. The cyst had
multicompartment structure, for what it was dealt with caution.
The wall of the cyst was highly vascular and stuck with choroid
plexus and many arterial feeders were coagulated and bisected. Part

venous occlusion. Continue next.......! |
