Abstract
We report our experience with a patient with infective endocarditis complicated by an extensive epidural abscess. The patient was a 55-year-old man who visited the internal medicine department with chief complaints of fever (≥38 °C) and back pain and was hospitalized. Mitral valve vegetation was observed on transesophageal echocardiography, and the patient was given antibiotics based on a diagnosis of infective endocarditis. He was referred to our department after developing lower back pain and pain in both thighs on day 5 of hospitalization. Although he did not have sensory disturbance or reduced leg muscle strength, body movement was difficult due to radiating pain in the legs. MRI revealed an epidural abscess extending from T4 to S1. As symptoms did not improve, surgery was performed. Intervertebral fenestration was performed from T6-7 to L3-4 alternately. The dura mater was compressed by inflammatory granulation tissue, and pale red pus was observed in the dural membrane. The symptoms improved following surgery, and the patient regained his ability to walk independently and was discharged.
