Objective We herein present a case involving a prevertebral abscess complicated by a spinal epidural abscess (SEA) secondary to intradiscal oxygen-ozone chemonucleolysis for treatment of a cervical disc herniation. Methods A 67-year-old woman with a history of intradiscal oxygen-ozone chemonucleolysis developed numbness and weakness in her right upper and bilateral lower extremities followed by urinary retention. Her symptoms did not respond to intravenous antibiotics alone. Magnetic resonance imaging of the cervical region revealed an extensive SEA anterior to the spinal cord, spinal cord myelopathy due to anterior compression by the lesion, and a prevertebral abscess extending from C2 to T1. She underwent surgical drainage and irrigation. Results The patient was successfully treated with surgical drainage and systemic antibiotic therapy without kyphosis. Streptococcus intermedius was detected within the abscess. All clinical symptoms except for the sensory deficit in the left leg were relieved. Conclusions The safety of intradiscal oxygen-ozone therapy requires further assessment. High-dose intravenous antibiotics should be initiated empirically at the earliest possible stage of prevertebral and epidural abscesses. Surgical drainage may be a rational treatment choice for patients with a prevertebral abscess complicated by an SEA and spinal cord myelopathy.
