Presentation
Low back pain. Lower limb weakness.
Patient Data
Anterior T2 hyperintense extradural collection with peripheral enhancement extends from above the imaged vertebrae to the mid-sacrum, with associated mild posterior displacement of the theca.
Hyperintensity of a markedly narrowed L3/4 intervertebral disc is on sagittal T2 fat suppressed images, within destructive change within the posterosuperior aspect of the L4 endplate. Bone marrow edema signal is noted within the L3/4 vertebral bodies.
Conclusion:
Anterior thoracolumbar epidural abscess extending from thoracic-midsacrum likely relating to discitis/osteomyelitis of L3/4.
Case Discussion
Spinal epidural abscess are is a rare but serious condition. MRI is the modality of choice for imaging and has high sensitivity and specificity for detection. Treatment is typically with surgical drainage and IV antibiotics.
