Spinal MRI showed an intramedullary heterogeneous nodule at the T5 level that was associated with extensive thoracic cord edema, while most hyperintense was associated with a marked hypointense core on sagittal T2-weighted image (A). Sagittal (B), coronal (C), and axial (D) T1-weighted images with contrast revealed obvious peripheral enhancement and no central enhancement.

T7 level on T2-weighted imaging. The post-gadolinium imaging indicated peripheral enhancement of the nodule in the dorsal aspect of spinal cord, while no enhancement of the diffuse high-signal lesion was observed on the T2-weighted images (Figures 1A-D).
Spinal MRI performed 1 month after penicillin therapy. Sagittal T2-weighted image (A) and enhanced T1-weighted image (B) showed that the nodule and perilesional edema were reduced.

One month after the onset, spinal MRI showed that the lesion was reduced compared with that before the treatment (Figures 2A,B), and the result of the CSF routine test was approaching normal.
Spinal MRI performed 6 months after penicillin therapy. Sagittal T2-weighted image (A) and enhanced T1-weighted image (B) showed normal spinal cord.

After 6-month follow-up, the symptoms of pain and numbness disappeared, and CSF studies and spinal MRI demonstrated normal results (Figures 3A,B).
