Thank you for asking Healthcare majic. My name is Dr Ehsan Ullah & I have gone through your query. Well hyperintense foci seen in MRI brain in T2 images are usually seen in normal aging but also in a number of neurological disorders or psychiatric illnesses.For example deep white matter hyperintensites are 2.0 to 3 times more likely to occur in bipolar disorder and major depressive disorder than normal persons. As the scenario mentioned above it suggests the hyperintense lesion showing on your mother s MRI Brain most strongly suggests brain parenchyma ischemia, micro-hemorrhages, gliosis, damage to small blood vessel walls and breaches of the barrier between the barrier of cerebrospinal fluid and the brain, or loss and deformation of the myelin sheath. I would like you to suggest you should take to your mother for neurologist checkup so that the underlying cause can be found and treated accordingly on time. Hope this may help you. Let me know if anything not clear. Thanks.
