What is a mass effect on the thecal sac?

Inflation of the bone tamps can result in the mechanical displacement of tumor and/or bone fragments into the spinal canal, potentially worsening or causing mass effect upon the thecal sac and resulting in symptomatic spinal cord, cauda equina, or nerve root compression.

How long can you live with a brain lesion?

The 5-year survival rate for people with a cancerous brain or CNS tumor is 36%. The 10-year survival rate is about 31%. Survival rates decrease with age. The 5-year survival rate for people younger than age 15 is more than 75%.

Can you live with brain lesions?

If not remedied, it could lead to death. Infections, harmful germs or bacteria in the brain. These can cause diseases like meningitis and encephalitis (both types of swelling (inflammation) of the brain).

What does effacement in the brain mean?

Sulcal effacement is a local secondary sign of mass effect in the cranium. Any lesion exerting mass effect on brain parenchyma can push adjacent gyri together, thereby displacing the CSF from the sulci.

What means effaced?

Effacement means that the cervix stretches and gets thinner. Dilatation means that the cervix opens. As labor nears, the cervix may start to thin or stretch (efface) and open (dilate).
