Why Is The Arachnoid Cyst Growing Again After Spinal Chord Surgery?
Hello Doctor, I had undergone spinal cord surgery due to arachnoid cyst (4CM) on last sep 2012. Recently, I went for MRI check-up after surgery review. Now, the cyst(1CM) is growing again. Can you please clarify the below queries? 1. whether CSF fluid is not drained properly from arachnoid layer during the surgery? 2. Why it is regrowing again after surgery? 3. Whether I need to undergo another surgery? Thanks in Advance Regards,

Hello and welcome to HCM,
Arachnoid cyst arises from the arachnoid layer of the meninges.
It does not occur due to improper drainage of CSF.
So, re-appearance of arachnoid cyst does not signify any alteration in CSF drainage.
Arachnoid cyst is mom-neoplastic growth and there is every possibility of re=appearance and regrowth.
Repeat surgery will be required when the lesion becomes symptomatic.
This can occur when the arachnoid cyst becomes large enough to compromise CSF production or drainage, any pressure symptom, etc.
You need to stay in touch with your neurologist/ neurosurgeon.
Thanks and take care
