Cerebellitis and acute obstructive hydrocephalus associated with Mycoplasma pneumoniae infection.

Mycoplasma pneumoniae is associated with a variety of extrapulmonary manifestations, including central nervous system inflammation. A 9-year-old boy presented with acute cerebellitis and M. pneumoniae infection, resulting in obstructive hydrocephalus requiring neurosurgical intervention. This case, along with 4 similar ones reported in the literature, suggests a distinct clinicopathologic sequence caused by mycoplasma infection.
