A 52-year-old female had acute urinary hesitancy, constipation, crural spastic asymmetric paraparesis and sensory level at T6 (hypopalesthesia left and thermo-algesic hypoesthesia on the right mainly on sacral dermatomes) one week after H1N1-trivalent immunization.

Magnetic resonance imaging showed thoracic intramedullary lesion (Figure) and absence of brain findings. Cerebrospinal fluid was normal including electrophoresis, viral polymerase chain reactions and cultures. HIV-serology, VDRL, and anti-nuclear antibodies were nonreactive.

Brown-Sèquard syndrome commonly results from traumatic or tumor injury and is rarely found in other etiologies1,2. Myelitis constitute possible adverse event temporally related to immunization and his notification contribute to post-marketing studies on the safety of immunobiological extensively used in population3.
