MR imaging in a 24-year-old intravenous drug abuser male shows heterogeneous signal in the subdural space in the lower thoracic spine (yellow arrow in a) on T1 W images. There is peripheral rim enhancement on post contrast T1 W images (red arrows in b and c), consistent with subdural abscess causing anterior displacement of the cord (marked as S in c). Also note the preserved epidural fat suggesting subdural location of the abscess (blue arrows in a and b). Biopsy of the abscess confirmed Pseudomonas aeruginosa infection
