What is Sulcal effacement?
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 does effacement mean in MRI?
Effacement means obliterating or erasing while right neural to the Intervertebral foramen: an opening between vertebrae through which nerves leave the spine and extend to other parts of the body. Lateral recess is descriptive term of the foramen. Here we have some erasing of the cervical cord in the image or picture.
What is the sulci of the brain?
The grooves or furrows in the brain, called sulci (plural of sulcus), are noticeably widened and there is shrinkage of the gyri (plural of gyrus), the well-developed folds of the brain’s outer layer. In addition, the ventricles, or chambers within the brain that contain cerebrospinal fluid, are noticeably enlarged.
What does mass effect mean on brain MRI?
The local pressure from a tumor or bleeding (hematoma) on adjacent parts of the brain. Mass effect is diagnosed by an MRI or CT scan which shows where the mass is and what it is pushing on.
What does effacement of ventricles mean?
In the context of radiology it should be taken to mean that a space or cavity has been obliterated by the external application of mass effect. For example, a brain tumor exerting mass effect on the adjacent brain may efface the adjacent cerebral sulci or ventricles. This implies that no CSF remains in those spaces.
What does effacement mean in medical terms?
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). This prepares the cervix for the baby to pass through the birth canal (vagina).
Does effacement happen before dilation?
Effacement happens hand-in-hand with dilation, although effacement may begin first. As with dilation, it can take weeks, days, or hours to reach full effacement. Once your cervix is 100 percent effaced and 10 cm dilated, you’re ready to start pushing your baby out into the world.
Is deep sulci related to intelligence?
Greater mean curvature of the deep sulcal areas in these regions was shown for the high verbal IQ group. These findings suggest that factors influencing verbal intelligence may emerge in the language areas early during cortical development and may be under tight genetic control.
What is the difference between a fissure and a sulcus?
The terms fissure and sulcus as they are classically de- fined are: a fissure separates one lobe from another, while a sulcus is within a lobe and delimits gyri. The fissures and sulci of the cerebral hemispheres can be arranged into three groups according to their location.
How do you know if a brain tumor is benign or malignant?
There is no way to tell from symptoms alone if a tumor is benign or malignant. Often an MRI scan can reveal the tumor type, but in many cases, a biopsy is required. If you are diagnosed with a benign brain tumor, you’re not alone.
What does mild effacement mean?
Efface is a term frequently used by radiologists, most often in the context of CSF-containing spaces in the brain (sulci and ventricles). This implies that no CSF remains in those spaces. If there is incomplete obliteration of the space then one can use the term ‘partial effacement’.
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). This prepares the cervix for the baby to pass through the birth canal (vagina). They also help move the baby into position to be born.
