Background:
Froin syndrome is characterized by xanthochromia and hypercoagulability of the cerebrospinal fluid (CSF) due to elevated protein levels. This entity results from blockage of the spinal canal by a mass lesion leading to an isolated caudal CSF space.
Case Description:
A 48-year-old male, who developed spasticity after a C6 spinal cord injury (SCI) 20 years earlier, presented with subobstruction of his intrathecal baclofen pump. A catheter access port aspiration revealed an extremely high protein concentration (38 g/L) with no signs of infection. Froin syndrome was confirmed when magnetic resonance imaging showed a complete obstruction of the spinal canal at the SCI level.
Conclusions:
We report the first case of Froin syndrome after SCI. Froin syndrome can impact intrathecal drug delivery and CSF diagnostics.
