Here, we report a rare case of a patient who developed successive VP shunt malfunction causing spastic muscle weakness in extremities associated cervical epidural venous distension and compressive myelopathy due to over-drainage of CSF through a defective VP shunt valve a decade after the initial shunt was placed. One should be aware and cognizant of this complication and carefully follow the symptoms and potentially utilize brain MRI with and without contrast to look at over drainage stigmata to avoid the development of neurological complications.
