Magnetic resonance imaging and computed tomography findings showed pyogenic arthritis of the right L4/5 facet joint with a paraspinal muscle abscess. Based on cultures of samples aspirated from the lesions, we diagnosed the patient with fungal arthritis of the lumbar facet joint. We treated him conservatively with an antifungal agent for a year, and the infection resolved. Conclusion: This is the first report of hematogenous fungal arthritis of a lumbar facet joint.
