Brief Answer:
There is nothing of concern in MRI report

Detailed Answer:
Hi,

Thank you for posting your query.

I have noted the child's history as well as MRI XXXXXXX report. First of all, I would like to reassure you that there is no need to worry about the findings.

Dermal sinus tract is a congenital (usually present from birth) developmental anomaly. In many cases, other associated abnormalities are found in the brain and spinal cord, which may cause brain infection, weakness of legs, etc. However, in this child's case, there are no associated abnormalities.

In my opinion, no action may be needed. If there is a risk of infection, minor surgery may be needed.

I hope it helps. Please get back if you have any follow up queries.

Best wishes,
Dr Sudhir Kumar MD DM (Neurology) XXXXXXX Consultant Neurologist
