Combined Striatum, Brain Stem, and Optic Nerve Involvement due to Mycoplasma pneumoniae in an Ambulatory Child

Abstract

In children, Mycoplasma pneumoniae encephalitis has been characterized by acute onset of an encephalopathy associated with extrapyramidal symptoms and symmetric basal ganglia with or without brain stem involvement on magnetic resonance imaging. Our case, showing unilateral optic neuritis, ophthalmoplegia, no extrapyramidal symptoms, and typical striatal involvement on magnetic resonance imaging, broadens the spectrum of varying clinical manifestations of childhood M. pneumoniae-associated encephalopathy.
