Extensive myelitis associated with Mycoplasma pneumoniae infection: Magnetic resonance imaging and clinical long-term follow-up

Myelitis is a severe neurological complication associated with Mycoplasma p neumoniae infections. Little is known about the extent and the reversibilit y of this myelitis, and reports on the value of spinal imaging are inconclu sive. To obtain more information on the diagnostic and prognostic value of spinal magnetic resonance imaging (MRI) we studied the clinical course and MRI long-term follow-up of two patients with extensive myelitis associated with M. pneumoniae infection. The neuroradiological findings were correlate d with the clinical extent of the spinal syndrome, but their reversibility preceded clinical improvement. These preliminary findings indicate that fol low-up spinal MRI may give valuable prognostic information in cases of M. p neumoniae associated myelitis and warrant further more systematic studies t o ascertain the relationship between spinal MRI findings and prognosis.
