  • Title: Fluoroscopy-guided percutaneous needle aspiration of posterior epidural abscesses: a report of two cases.
    Author: Ross AB, Tang JY, Rosas HG, Bice MJ.
    Journal: Spinal Cord Ser Cases; 2019; 5():43. PubMed ID: 31632702.
    Abstract:
    INTRODUCTION: Spinal epidural abscesses are most commonly treated with surgical decompression and antibiotics or in specific instances managed medically with antibiotic therapy alone. Image-guided percutaneous aspiration as an alternative to surgery has only rarely been reported in the literature. CASE PRESENTATION: We report two cases of successful fluoroscopy-guided needle aspiration of posterior epidural abscesses. Case 1 is a 48-year-old man who presented with several days of escalating back pain and constitutional symptoms with MRI showing a posterior epidural abscess at L2-L3 causing spinal stenosis. The patient remained neurologically intact. Percutaneous needle aspiration of the collection provided dramatic pain relief with the aspirate growing methicillin sensitive Staphylococcus aureus. The patient made a full recovery on antibiotic therapy. Case 2 is an 81-year-old man who presented with worsening upper back pain and was found to have osteomyelitis/discitis with a large posterior epidural abscess in the thoracic spine. Needle drainage was performed with the sample growing Bacteroides fragilis. This patient also responded successfully to nonsurgical management with full recovery after appropriate antibiotic therapy. DISCUSSION: In carefully selected patients, image-guided needle aspiration of posterior epidural abscesses may be a viable and less invasive alternative to surgery.
