Abstract
Introduction: We present a case of acute non-communicating hydrocephalus due to fat droplet obstruction of the cerebral aqueduct, fifty-one years after resection of a spinal dermoid tumor.
Case Report: A 71-year-old male presented with sudden onset of neck pain and gait instability. He had prior complete surgical resection of a cervical dermoid cyst in 1959. Follow up magnetic resonance imaging (MRI) in 2007 showed intracranial fat signal droplets within the posterior fossa. An MRI examination obtained in 2012 demonstrated hydrocephalus consequent to fat droplet obstruction at the aqueduct of sylvius which was not present in MRI study done in 2007.
Conclusion: To our knowledge there are no published reports of delayed post spinal dermoid resection subarachnoid fat droplet migration leading to acute non-communicating hydrocephalus.

Keywords: Dermoid cyst, Hydrocephalus, Intra-spinal dermoid, Cerebral aqueduct
