ABSTRACT

Introduction: anterior cervical discectomy is one of the most common procedures performed by spine surgeons, the gold standard in this treatment is the anterior cervical discectomy. Among the complications resulting from discectomy is cerebrospinal fluid (CSF) fistula. Material and methods: this is an observational study that compiles cases of CSF fistulas presented in the last 12 years where the presence of a sign that was very constant in the presentation and clinical evolution of the CSF fistula was observed. Results: all three patients underwent simple magnetic resonance imaging of the cervical spine. In all three patients there was an arrow-shaped hyperintensity. Conclusions: the arrow sign can be a very reliable indicator for the diagnosis and follow-up of CSF fistulas originated in cervical spine discectomy performed via anterior approach. It is best visualized in the T2 sequence in the sagittal section of a simple MRI of the cervical spine. Its identification can help us to make decisions about this minor complication.
