Spinal Subdural Abscess in the Cervical Region: A Case Report

The authors present a patient with a spinal subdural abscess (SSA) in the cervical region and review the relevant literature. A 48-year-old man suffering from intractable high fever and back pain was admitted to our hospital with a diagnosis of meningitis. Despite antibiotic therapy, his condition deteriorated and he developed neurological deficits including left hemiparesis, sensory disturbance and bladder dysfunction. MR images of the cervical spine with gadolinium contrast revealed a circumferentially enhancing lesion anterior to the spinal cord that extended from the C4 to C6 level and compressed the spinal cord. After an urgent laminectomy extending from C4 to C6, the subdural abscess that consisted of purulent material and a thick capsule was irrigated and drained. Staphylococcus aureus was cultured from the abscess and he received antibiotic therapy postoperatively for 14 weeks. The high fever and the back pain subsided immediately and his neurologic condition gradually recovered. The majority of SSA cases involve the thoracic or lumbar region and are rarely found in the cervical region. Because they are associated with a high morbidity, early diagnosis with MRI and urgent surgical interventions including decompressive laminectomy, copious irrigation and drainage followed by appropriate antibiotic therapy are vital.
