Acute transverse myelitis due to Mycoplasma pneumoniae infection.

We examined a woman who had acute transverse myelopathy (ATM) associated with respiratory illness due to Mycoplasma pneumoniae. To our knowledge, only one previously described case documented this relationship with serologic studies of spinal fluid. Since 16% to 35% of ATM patients experience antecedent respiratory illness, evidence of M pneumoniae infection should be sought in all cases.
