case_images: Cervical Magnetic Resonance Imaging (MRI) at clinical onset demonstrating a longitudinally extensive signal abnormality involving the cervical spinal cord, extending from the obex to D3. The cord appears markedly swollen, both gray and white matter are involved, and post-contrast sequences demonstrate marked cord enhancement between C3 and C5 (red arrows). Findings are compatible with acute longitudinally extensive transverse myelitis (LETM).

case_images: C3-C5 level which was compatible with acute Longitudinally Extensive Transverse Myelitis (LETM) (Figure 1).
case_images: Follow-up MRI scans at 20 (A) and 55 (B) days, showing progressive reduction of the spinal cord swelling and contrast enhancement. In (B), contrast enhancement has completely regressed, due to blood-brain barrier restoration, and the spinal cord shows a near-normal appearance with no residual disease. No spinal cord atrophy is noted.

case_images: Follow-up MRIs, performed after 20 and 55 days, respectively, (Figure 2), showed progressive improvement of spinal cord oedema and enhancement in parallel with a complete clinical recovery.
