What does irregular appearance of the brain surface overlying in the brain mean?

What does irregular appearance of the brain surface overlying in the brain mean?

Out of Context: I am sorry but you surely must understand that you gave us words that are meaningless, out of context and in no way definitive enough to give you any kind of medical interpretation. There is nothing here that gives diagnosis, medical history, reason for the test, what test it was, etc. ...Read more

Bone (Definition)

Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more

Is the gray matter inside of the spinal cord but outside of the brain?

Is the gray matter inside of the spinal cord but outside of the brain?

Almost correct: The gray matter (nervous system tissue with cell bodies) is inside the cord, surrounded by white matter (axons: nerve fibers going to & from the brain). While there is gray matter on the surface of the brain, it is also present in collections deep inside the brain. The organization of the central nervous system is quite complex. ...Read more

What is calcification of the brain tissue?

What is calcification of the brain tissue?

Depends where: Excess calcium deposited in the tissues, usually sufficient that it can be seen on a ct scan. Whether it is a problem depends, in part, on where there is calcium. Calcium in the choroid plexus and pineal regions is a normal part of aging, for example. ...Read more

Can you visualize in the MRI views if the cranial nerves are encroaching in the skull base foramen?

Can you visualize in the MRI views if the cranial nerves are encroaching in the skull base foramen?

MRI of cranial nerve: Mri can visualize the origins of the cranial nerves. As the nerves exit the brainstem and enter various canals and foramina, they become smaller and a bit more difficult to visualize directly. Not entirely sure what you mean by "encroaching in" the skull base foramen, but there can be direct/indirect findings on MRI if there is a problem with a cranial nerve at the skull base. ...Read more

Flow-voids in the major vessels in the base of the brain appear grossly patent.low cerebellar tonsils about 5 mm below the foramag?

Flow-voids in the major vessels in the base of the brain appear grossly patent.low cerebellar tonsils about 5 mm below the foramag?

Not Abnormal: Cerebellar tonsils at 5 mm below foramen magnum is a normal variant and would not be expected to have clinical significance. Flow voids mean that blood is indeed flowing in your vessels, a good thing. ...Read more

What are the effects of a tumor in the membrane that surrounds the brain and spinal cord?

What are the effects of a tumor in the membrane that surrounds the brain and spinal cord?

Menigeal: Carcinomatosis (if a cancer) or lymphomtous or leukemic menigitis. The former carries a poor prognosis. It is addressed in children with cranio-spinal irradiation and intr-thecal chemotherapy. In adults with solid tumors, it is a mark of quite advanced disease, causes cranial neuropathy, and weakness. Rarely only site of disease. ...Read more

Erosion of the floor of the anterior cranial fossa and crista galli. What does that mean? Have metastasis to brain and lungs from renal cancer

Erosion of the floor of the anterior cranial fossa and crista galli. What does that mean? Have metastasis to brain and lungs from renal cancer

Sorry to hear this: Suspect there is involvement of skull and brain, and indeed may be presence of carcinomatous meningitis. This is a difficult development and hopefully an oncologist can assist the current difficult issues. ...Read more

Is swelling of brain tissues due to a brain tumor the same as raised intracranial pressure?

Is swelling of brain tissues due to a brain tumor the same as raised intracranial pressure?

Similar: Brain tumors can cause an increase in intracranial pressure but there are other things that can cause this. Increased intracranial pressure is just the pressure inside of the skull. This pressure can be increased by tumors but also by injury, bleeding, swelling and fluid blockages. ...Read more

What is the significance of MRI findings of amount of fat surrounding exiting nerve roots of spine?

What is the significance of MRI findings of amount of fat surrounding exiting nerve roots of spine?

Nerve fat: Each nerve has a ring of protective fat around it on MRI this seen as a bright signal so a ring of brightness around a nerve is normal and good to little fat around the nerve implies crowding or pressure contact of something other than fat like bone or disc. Ouch. ...Read more
