Doctor insights on: Basal Ganglia Lesion

Basal Ganglia (Definition)

This is the term for several areas of the brain that work together as a functional unit: the striatum (caudate and putamen), the globus pallidus, the substantia nigra, and the subthalamic nucleus. The most well known function of the basal ganglia is voluntary motor control, but it is also involved in development of routine behaviors; eye movements; and ...Read more

Can operate 14x6x6 lesion lying just inferior to the basal ganglia inferolateral to putamen, possible contiguity wth the claustrum anteroinferiorfly?

Can operate 14x6x6 lesion lying just inferior to the basal ganglia inferolateral to putamen, possible contiguity wth the claustrum anteroinferiorfly?

Is surgery needed?: That area is able to be reached surgically, but the real question is: does this lesion need surgery? Many findings on MRI do not require surgery. Sometimes, watching and waiting (with repeat mris) is the best course. Too many variables here to fully answer this question. Consultation with a neurosurgeon is warranted. ...Read more

Small low-density lesion in left basal ganglia could be due to prior ischemia that the doctor never mentioned should i have this further investigated?

Small low-density lesion in left
basal ganglia could be due to prior ischemia that the doctor never mentioned should i have this further investigated?

Yes- you should: Sometimes findings like this are made incidentally. It is surprising, but people may have these without any symptoms. While they are not normal, they can be benign if the follow up shows this was a small stroke and that all stroke risk factors (like smoking, blood pressure) are well accounted for and minimized. ...Read more

7mm ovoid lesion fluid density shown within posterior inferior aspect of right basal ganglia small vessel coursing through it incidental virchow robin?

7mm ovoid lesion fluid density shown within posterior inferior aspect of right basal ganglia small vessel coursing through it incidental virchow robin?

Difficult to tell: without actually looking at the scan. Virchow Robin spaces are found normally and accompany blood vessels as they penetrate the brain. They contain cerebrospinal fluid and if they expand they can look quite pathological however it would be difficult to tell for sure without looking at the scan and knowing more. Would be happy to provide a virtual consult if needed. Best of luck! ...Read more

I have a lesion on the left side of my brain in the basal ganglia and i also have left leg paralysis. What could be the cause?

I have a lesion on the left side of my brain in the basal ganglia and i also have left leg paralysis.  What could be the cause?

Paralysis: Left basal ganglia lesion would cause right sided weakness. Left leg paralysis would be from a right sided lesion in the brain above the brain stem. A spinal cord lesion on the same side or below where the corticospinal fibers cross in the brain stem would cause left leg weakness. See you neurologist or neurosurgeon to identify the source of the left leg weakness. ...Read more

Is a small (3mm) hyperintensity in the basal ganglia significant or not. Also what are the causes?

Is a small (3mm) hyperintensity in the basal ganglia significant or not. Also what are the causes?

MRI brain: It is likely not significant however the results of your MRI study should be discussed with a neurologist to put into context what the 3 mm spot means relative to the entire MRI study and your medical problems. The causes of the bright spots on MRI studies (T2) of the brain are many and range from aging, migraines, mini-strokes, bleeding, atherosclerosis, multiple sclerosis, and metastatic tumors. ...Read more
