Afp normal, enlarged brain ventricles, could it be a neural tube defect?

Neural tube defect

Brain
If AFP is normal there is likely not a neural defect, but the test is not 100% positive.

Afp normal, enlarged brain ventricles, is it still possible to have a neural tube defect NTD?

AFP

Head-brain
A normal AFP reduces the risk of an open neural tube abnormality. Enlarged cerebral ventricles are usually not associated with neural tube abnormalities.

Please tell me, could a brain tumor cause an enlarged ventricle?

Yes

Head-brain
Brain tumors can block the normal circulation of cerebral spinal fluid resulting in fluid backing up in the brain and causing dilatation of the ventricular system.

What does a narrow 4th brain ventricle mean?

It depends

Cerebrum
It depends if you have any symptoms suggesting a cerebrospinal fluid circulation problem. If you have no symptoms it may just be an anatomical finding.

Brain right ventricle 8mm lesion -cyst or tumor?

Hard to say

Head-brain
If the interpretation on the MRI by the radiologist is that it is a cyst, then it is likely benign. It also depends if there is any area of enhancement that would suggest a tumor. Also if you have serial MRI scans, you can tell if it is getting bigger or changing which is more likely a tumor. The location in the ventricle is important too. If it obstructs the foramen it could be a problem.

Possible to have one one ventricle brain shunt your whole life?

Yes

Open-uri20121105-25202-57g9g
I still see many patients who have had their shunt in for 30 or 40 years. Most remarkably, the shunt is frequently still functioning. It is more common to have multiple shunts in your lifetime, but not impossible at all to have one last for decades. Living in Morrilton, if you need a good neurosurgeon in Little Rock, Dr. Krisht or Dr. Reding are among the very best.

What should be the size of left ventricle and brain of 21 week fetus?

Please clarify

Head-brain
This is a little different of a question. Can you clarify whether you are referring to the left ventricle of the heart and the ENTIRE size of the brain (as in volume, weight, or some other measure?). Or are you asking about the size of the left ventricle of the brain? And why only the left ventricle and not the right?

Dr. Shaym Puppala answered:

Can creutzfeldt-jakob disease cause brain ventricles to enlarge?

Yes.

Prion
Creutzfeldt-Jakob Disease (CJD) is an incurable, degenerative disease of the brain caused by incorrectly folded proteins. As the brain cells are destroyed, the brain tissue can shrink and become atrophied. The ventricles of the brain, which are fluid containing structures, can become bigger due to surrounding brain tissue loss. Thanks to M. DiNapoli, med student.

How dangerous is an enlarged ventricle?

Enlarged Ventricle

Ventricle
An enlarged ventricle is usually a symptom of another undrlying problem. There are idiopathic or unknown causes but generally hypertension is the main culprit. Pulmonary hypertension causes enlargement of the right, and systemic hypertension causes enlargement of the left. Danger depends on the degree and type of enlargement. You should seek further evaluation by a Cardiologist!

Depends.....

It really depends on the difference in size from a benign condition to something very serious.
