Nocardial spinal epidural abscess with lumbar disc herniation

Abstract

RationaleNocardial spinal epidural abscess is rare. The diagnosis is often difficult to make and, if delayed, poses a high risk of long-term disability. Nocardial spinal epidural abscess with severe lumbar disc herniation has not previously been reported.Patient concernsA 50-year-old man presented with progressive lumbago and leg pain for 6 weeks after receiving acupuncture therapy, and then the patient suddenly occurred urine retention after walking.DiagnosesClinical examination revealed sign of cauda equina syndrome. Magnetic resonance imaging (MRI) revealed a Lumbar(L)4 to L5 disc herniation, L3 to Sacrum(S)1 epidural abscess, and L2 to S1 paravertebral abscess. The causative organism was Nocardia farcinica.InterventionsAn urgent paravertebral abscess debridement and right L4 to L5 laminectomy were performed. Simultaneously, the disc tissue protruding into the spinal canal was removed, as well as irrigation and drainage. And antimicrobial treatment was continued for 12 months.OutcomesFortunately, the patient was able to walk with a cane and urinate autonomously without a catheter, although this remained difficult 7 days after surgery. After 1 year of treatment, the patient has recovered completely and returned to work.LessonsNocardial spinal epidural abscess with severe lumbar disc herniation is extremely rare. Pain from spinal degenerative diseases often masks the early symptoms of spinal infection. It's worth noting that invasive treatment of spine is a way of causing spinal nocardial infection.

“…Authors report an incidence rate of 500–1000 cases per year in the United States [1] , [2] while a recent review found the prevalence varied between 0.4% and 3.6% among immunosuppressed patients [3] .…”

Disseminated Nocardia farcinica involves the spinal cord: a case report and review of the literature

“…Our case is consistent with this pattern, that is multiple cavities occurring and changing over a short period of time. The next is the nervous system, common imaging findings include brain abscess, granulomatous formation or diffuse infiltration [ 16 , 17 ], meningitis, epidural and paraspinal abscesses [ 18 , 19 ]. This case has no typical brain MRI performance.…”

“…It is worth noticing that the patient has a history of liver cancer and his White Blood Cell (WBC) count was lower than normal. FeiMa and John W. Wilson mentioned that solid cancer could induce intervertebral fungal infection [8,12]. It is speculated that the long history of liver cancer suppressed the patient's immune function, thus leading to fungal infection of the spine.…”
