Froin's Syndrome Secondary to Traumatic and Infectious Etiology

Abstract

The protein level in the cerebrospinal fluid (CSF) is an important diagnostic tool and, when abnormal, can provide clinicians with clues to the etiology of a patient's condition. Froin's syndrome has been described in previous literature as the combination of xanthochromia, elevated protein, and hypercoagulated CSF. The pathophysiology behind Froin's syndrome is thought to be due to stagnant CSF causing passive and/or active diffusive processes, resulting in hyperproteinosis and hypercoagulation. We present a case of Froin's syndrome in a patient with cervical spine trauma whose extraordinary level of CSF proteinosis helped raise suspicion for underlying obstructive and infectious etiology.
