BACKGROUND: Guillain-Barré syndrome is an acute immune-mediated peripheral polyneuropathy. Neuroimaging findings from patients with this syndrome have revealed gadolinium enhancement in the cauda equina and in the anterior and posterior nerve roots, but intra-spinal lesions have never been described.
AIM: Herein, we report, for the first time, bilateral spinal anterior horn lesions in a patient with an acute motor axonal neuropathy form of Guillain-Barré syndrome.
CASE: The patient was a previously healthy 13-year-old Japanese girl, who exhibited acute-onset flaccid tetraplegia and loss of tendon reflexes.
RESULTS: Nerve conduction studies revealed motor axonal damage, leading to the diagnosis of acute motor axonal neuropathy. Notably, spinal magnetic resonance imaging revealed bilateral anterior horn lesions on T2-weighted imaging at the Th11-12 levels, as well as gadolinium enhancement of the cauda equina and anterior and posterior nerve roots. The anterior horn lesions were most prominent on day 18, and their signal intensity declined thereafter. Although intravenous treatment with immunoglobulins was immediately administered, the motor function was not completely regained.
CONCLUSION: We propose that anterior spinal lesions might be responsible for the prolonged neurological disability of patients with Guillain-Barré syndrome, possibly produced by retrograde progression from the affected anterior nerve roots to the intramedullary roots, and the anterior horn motor neurons.
