Intramedullary Arachnoid Cyst of Spinal cord


Spinal Arachnoid Cysts are uncommon lesion, divided into intra dural or extra dural.
Intra dural cysts being much less common. Symptomatic spinal Arachnoid Cysts in the pediatric age group are rare.

I am posting an unusual case of intra medullary cyst of Spinal cord in a 19-year-old female who presented with lower dorsal and lumbar region pain and mild quadriparesis.
MRI study shows a solitary intra dural, unilocular, clear, Csf signal intensity cyst on ventral aspect of cord invaginating the cord best depicted on axial sections with focal expansion of cord.
Lesion is non enhancing on post contrast. No any adjacent enhancing nodule or odema.

Imaging wise possibility of an Intramedullary Arachnoid Cyst was given.
Aspiration of cyst attempted but showed recurrence which was expected.
Laminectomy with excision of the cyst done.

Intra operative and histopathological findings were suggestive of an Arachnoid Cyst.

Interesting. As a chiropractor, cases like this can be really helpful for us to gain more knowledge about our field of study and to know what to do during our actual practice.
