Abstract
Acute transverse myelitis (ATM) is a rare, immune-mediated disorder of the spinal cord characterized by sensory, motor, and autonomic dysfunction. Although the human papillomavirus (HPV) vaccine is widely regarded as safe, isolated reports have suggested a potential temporal association with autoimmune neurological events, including ATM. We present a case of a 21-year-old woman who developed ATM two weeks following administration of the first dose of the HPV vaccine (Cervarix). The clinical presentation included rapid-onset paraparesis, sensory deficits, and sphincter dysfunction. An MRI revealed a T2-hyperintense lesion at the Th10-Th12 level. A cerebrospinal fluid analysis showed elevated protein levels. The patient underwent corticosteroid therapy, plasmapheresis, and IVIG, followed by a comprehensive, individualized rehabilitation program. This included balance and stability training, Redcord-based neuromuscular activation, electrostimulation, and pelvic floor therapy. Although no causal link between HPV vaccination and ATM has been established, this case emphasizes the importance of considering post-vaccinal autoimmune phenomena. More importantly, it illustrates the critical role of early, targeted rehabilitation-particularly pelvic floor re-education and neuromodulation-in improving outcomes in patients with significant motor and autonomic deficits.
