Juxtafacet cyst infection.

Purpose: In the realm of spinal surgery, infections have multiple etiologies and sites of origin. In this case series, we describe a juxtafacet cyst spinal infection that can often be missed or attributed to common symptomology of benign processes despite florid infection.
Methods: In rare instances, the juxtafacet cyst may become infected and require direct intervention. This case report attempts to describe the prodrome leading to such a diagnosis and two different ways to manage an infected facet cyst.
Results: Management of spinal infections varies due to the multiplicity of causes and location of infections. The juxtafacet cyst infection should remain a part of the differential diagnosis for low back pain as their presentation often mimics more common presenting complaints.
Conclusions: In our two patient presentations, both were diabetics and had remote histories of cancer that necessitated chemotherapy or radiation therapy. They also seemingly had de novo onset of infected juxtafacet cyst. The variety of causes and presentations of spinal infections should heighten the astute surgeon to be suspicious of these entities and thus intervene early with appropriate management.
