catheter within the left scalp subcutaneous tissue

[fat_flying_pigs]

Hi I recently had an MRI done on my head and the results came back saying there is a cantheter within the left scalp subcutaneous tissue. I have no idea how it got there. I have never had any surgury on my head. What would be a reason for having this in my head? Should it have been taken out? Should i be concerned about this?

Thank you in advance for any info.
